Abstract:

Flexible grasping robots are needed for enabling automated, profitable and competitive production of small batch sizes including complex handling processes of often fragile objects. This development will create new conditions for value-adding activities in the production of the future world. The paper describes the related research work we have developed for sensor design, exploration and control for a robot gripping system, in order to analyze normal forces applied on the tactile pixels for gripping force control and generate tactile images for gripping positioning and object recognition. Section 1 gives an introduction of principles and technologies in tactile sensing for robot grippers. Section 2 presents the sensor cell (taxel) and array design and characterization. Section 3 introduces object recognition and shape analysis ideas showing a few preliminary examples, where geometrical features of small objects are identified. Slip detection in order to define optimum grasp pressure is addressed in section 4. The paper will conclude by addressing future ideas about how to judge or forecast a good grasp quality from sensory information.

Abstract:

Tactile defensiveness is a common feature in neurodevelopmental disorders (NDDs). Since the first studies, tactile defensiveness has been described as the result of an abnormal response to sensory stimulation. Moreover, it has been studied how the tactile system is closely linked to socio-communicative development and how the interoceptive sensory system supports both a discriminating touch and an affective touch. Therefore, several neurophysiological studies have been conducted to investigate the neurobiological basis of the development and functioning of the tactile system for a better understanding of the tactile defensiveness behavior and the social touch of NDDs. Given the lack of recent literature on tactile defensiveness, the current study provides a brief overview of the original contributions on this research topic in children with NDDs focusing attention on how this behavior has been considered over the years in the clinical setting.

Abstract:

Tactile perception enables people with visual impairments (PVI) to engage with artworks and real-life objects at a deeper abstraction level. The development of tactile and multi-sensory assistive technologies has expanded their opportunities to appreciate visual arts. We have developed a tactile interface based on the proposed concept design under considerations of PVI tactile actuation, color perception, and learnability. The proposed interface automatically translates reference colors into spatial tactile patterns. A range of achromatic colors and six prominent basic colors with three levels of chroma and values are considered for the cross-modular association. In addition, an analog tactile color watch design has been proposed. This scheme enables PVI to explore artwork or real-life object color by identifying the reference colors through a color sensor and translating them to the tactile interface. The color identification tests using this scheme on the developed prototype exhibit good recognition accuracy. The workload assessment and usability evaluation for PVI demonstrate promising results. This suggest that the proposed scheme is appropriate for tactile color exploration.

Abstract:

Specialized grippers used in the industry are often restricted to specific tasks and objects. However, with the development of dexterous grippers, such as humanoid hands, in-hand pose estimation becomes crucial for successful manipulations, since objects will change their pose during and after the grasping process. In this paper, we present a gripping system and describe a new pose estimation algorithm based on tactile sensory information in combination with haptic rendering models (HRMs). We use a 3-finger manipulator equipped with tactile force sensing elements. A particle filter processes the tactile measurements from these sensor elements to estimate the grasp pose of an object. The algorithm evaluates hypotheses of grasp poses by comparing tactile measurements and expected tactile information from CAD-based haptic renderings, where distance values between the sensor and 3D-model are converted to forces. Our approach compares the force distribution instead of absolute forces or distance values of each taxel. The haptic rendering models of the objects allow us to estimate the pose of soft deformable objects. In comparison to mesh-based approaches, our algorithm reduces the calculation complexity and recognizes ambiguous and geometrically impossible solutions.

Abstract:

In early childhood, touch is the fi rst means of communication with the surrounding world. How the parents touch and hold a baby and how frequently they touch it affects the emotional and physical development and health of the child. Studies demonstrate that deprivation of human contact for children usually causes them future anxiety and nervousness. The main assumptions of the MNRI® NeuroTactile therapy modality is to increase and create kinesthetic awareness in the body of a patient; to regulate functions of skin receptors by activation of the sense of touch and proprioception targeted at their neurological aspects – receptors, dermatomes, refl ex circuits and their functions. Techniques of the NeuroTactile Therapy created by Dr. Masgutova rely on providing a controlled amount of sensory stimuli and sensory-proprioceptive information for tactile and also proprioreceptive systems, particularly, to create and facilitate spontaneous physiological adaptive responses. The result is to improve the functions of the neurosensory motor system and overall neuro-development. The aim of this type of tactile training is to activate natural mechanisms for development, regulation and normalization of tactile perception, muscle tension, and also to promote sensory and sensory-motor integration mechanisms, develop kinesthetic awareness while reducing or eliminating stress and increasing neuroplasticity.

Abstract:

Spatial navigation within a real 3-D maze was investigated to study space perception on the sole basis of tactile information transmitted by means of a ‘tactile vision substitution system' (TVSS) allowing the conversion of optical images—collected by a micro camera—into ‘tactile images’ via a matrix in contact with the skin. The development of such a device is based on concepts of cerebral and functional plasticity, enabling subjective reproduction of visual images from tactile data processing. Blindfolded sighted subjects had to remotely control the movements of a robot on which the TVSS camera was mounted. Once familiarised with the cues in the maze, the subjects were given two exploration sessions. Performance was analysed according to an objective point of view (exploration time, discrimination capacity), as well as a subjective one (speech). The task was successfully carried out from the very first session. As the subjects took a different path during each navigation, a gradual improvement in performance (discrimination and exploration time) was noted, generating a phenomenon of learning. Moreover, subjective analysis revealed an evolution of the spatialisation process towards distal attribution. Finally, some emotional expressions seemed to reflect the genesis of ‘qualia’ (emotional qualities of stimulation).

Abstract:

Confronted with the loss of one type of sensory input, we compensate using information conveyed by other senses. However, losing one type of sensory information at specific developmental times may lead to deficits across all sensory modalities. We addressed the effect of auditory deprivation on the development of tactile abilities, taking into account changes occurring at the behavioral and cortical level. Congenitally deaf and hearing individuals performed two tactile tasks, the first requiring the discrimination of the temporal duration of touches and the second requiring the discrimination of their spatial length. Compared with hearing individuals, deaf individuals were impaired only in tactile temporal processing. To explore the neural substrate of this difference, we ran a TMS experiment. In deaf individuals, the auditory association cortex was involved in temporal and spatial tactile processing, with the same chronometry as the primary somatosensory cortex. In hearing participants, the involvement of auditory association cortex occurred at a later stage and selectively for temporal discrimination. The different chronometry in the recruitment of the auditory cortex in deaf individuals correlated with the tactile temporal impairment. Thus, early hearing experience seems to be crucial to develop an efficient temporal processing across modalities, suggesting that plasticity does not necessarily result in behavioral compensation.

Abstract:

The fact that sensory modalities do not become functional at the same time raises the question of how sensory systems and their particular experiential histories might influence one another. Few studies have addressed how modified stimulation to earlier-emerging modalities might influence the functioning of relatively later-developing modalities. Previous findings have shown that enhanced prenatal tactile and vestibular (proximal) stimulation extended and delayed normal patterns of auditory and visual responsiveness to species-typical maternal cues in bobwhite quail respectively. Although these results were attributed to the increased amount of sensory stimulation, these results may be a function of when prenatal augmented proximal exposure took place. To address this issue the present study exposed groups of bobwhite quail embryos to equivalent amounts of augmented tactile and vestibular stimulation either at a time when a later-emerging modality (auditory or visual) was beginning to functionally emerge or when it had already functionally emerged. Results indicate that differences in the timing of augmented tactile and vestibular stimulation led to differences in subsequent auditory and visual responsiveness. Embryos were unable to learn a maternal call prior to hatching when enhanced proximal stimulation coincided with auditory functional emergence implicating a deficit in auditory functioning, but did learn a maternal call when enhanced proximal stimulation occurred after auditory functional emergence. Augmented proximal stimulation that coincided with visual functional emergence did not appear to influence normal visual responsiveness, but when proximal stimulation occurred after visual emergence, chicks displayed an accelerated approach response to species-typical visual cues. These findings support the view that the timing of enhanced stimulation to earlier-emerging modalities is important, and have meaningful implications for intersensory theory and research.<br>Ph. D.

Abstract:

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Materials Science and Engineering, 2013.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 82-86).<br>MEMS (Microelectromechanical System) pressure sensor arrays are gaining attention in the field of underwater navigation because they are seen as alternatives to current sonar and vision-based systems that fail to navigate unmanned undersea vehicles (UUVs) in dark, unsteady and cluttered environments. Other advantages of MEMS pressure sensor arrays include lower power consumption and that their passive nature makes them covert. The goal of this work focuses on the development of a flexible pressure sensor array for UUVs, where the sensor array is inspired by the ability of fish to form three-dimensional maps of their surroundings. Fish are able to decipher various pressure waves from their surroundings using the array of pressure sensors in their lateral line sensory organs that can detect minute pressure differences. Similarly, by measuring pressure variations using an engineered pressure-sensor array on the surface of an UUV, this project hopes to aid UUVs in the identification and location of obstacles for navigation. The active material of the pressure sensor array is a porous polydimethylsiloxane (PDMS)-carbon black composite made out of a sugar sacrificial scaffold that shows great promise for satisfying the proposed applications. The proposed device structure is flexible, easily fabricated, cost efficient and can be implemented on a large-area and curved UUV surface. Although hysteresis occurs during the electromechanical test, the piezoresistivity of this porous PDMS-carbon black composite is reversible and reproducible. Compared to its non-porous counterpart, this porous composite shows a six-times increase in piezoresistivity and a greatly reduced Young's Modulus. When tested underwater, this porous composite was able to differentiate water waves that had a frequency of 1 Hz and 2 Hz, which is promising for its underwater application. This porous composite was also extended to the application of tactile sensors using a different device architecture, which showed excellent response under mechanical testing.<br>by Mun Ee Woo.<br>S.M.

Abstract:

This PhD thesis describes the design and development of a new resonator based tactile sensitive probe. This new sensor was proposed because of the increasing need for high-sensitivity, high-speed touch-sensitive probes in coordinate metrology due to the ever-growing demand for precision and reliability at sub-micron level accuracy. Extensive background research on the current development of touch trigger probes has shown that designs based on the resonator principle have potential for minimising lobing effects and the false triggering associated with most commercially available probes. Resonant based sensors have been investigated over many decades and used very successfully in a wide range of applications. However their commercial exploitation in the field of precision engineering has not been particularly successful. One reason for such slow progress is the complexity of the interaction between oscillatory probes and typical engineering surfaces in less than ideal environments. The main aim of this research was to design a high precision resonator based tactile sensitive probe and to investigate the causes of parametric changes on resonant touch sensors both before and during contact with a variety of engineering surfaces in order to achieve a better understanding of contact mechanisms. The four main objectives were: preliminary design and characterisation of a resonator based touch sensor; development of the mathematical model which predicts parametric changes on a resonant probe considering both near surface effects and mechanical contact; experimental verification of mathematical predictions; and an investigation into possible commercial exploitation of the new probe in precision applications. A novel resonator based tactile sensor that utilises the piezoelectric effect was designed and characterised. The design exploits the fact that when a stiff element (probe) oscillating near or at its resonance frequency comes into contact with the surface of another body (workpiece), the frequency of vibrational resonance of the probe changes depending on the properties of the workpiece. The phase-locked loop frequency detection technique was employed to track changes in frequency as well as in the phase of the resonant system. The initial characterisation of the touch sensor has shown a sensitivity to contact of less then 4 mN, a high triggering rate and good repeatability. The potential for application in measuring material properties was also demonstrated. As a result of the characterisation a comprehensive mathematical model was developed. This novel model was based on Hertzian contact mechanics, Rayleigh's approximate energy method and work carried out by Smith and Chetwynd on the analysis of elastic contact of a sphere on a flat. The model predicts that phase and frequency shift of a resonator based sensor can either increase or decrease depending on the dominant phenomena (added mass, stiffness and damping) in the contact region. Observation of dynamic characteristics at either side of the resonant frequency can be used to identify the predominant effect. In order to confirm the model experimentally, another prototype probe was developed. The new sensor was engaged in observations of contact mechanisms with engineering surfaces. The experimental results have showed favourable agreement with the developed mathematical model. This enabled a better understanding of contact phenomena uncovering possibilities for the application of resonant sensors in many other areas. The research has shown that the new probe has potential in contact measurements where it can be used for the quantitative assessment of the physical properties of different materials (modulus of elasticity, density and energy dissipation) and also in non-destructive hardness testing. It was shown that the device can be successfully used in coordinate metrology as a touch trigger probe and as a 3D vector probe. Finally, applications can also be found in surface topography as a surface characterisation instrument. It is intended that the research described in this thesis will make an important contribution in the area of resonator based probes, providing a better understanding of the causes of parametric changes on the oscillatory sensor during contact with the object being measured. Consequently, this will enable a more effective exploitation of resonant probes for a broad range of precision applications.

Abstract:

Glaucoma is a group of diseases that lead to a progressive loss of vision in the majority of the cases due to elevated intraocular pressure (IOP). Glaucoma is the second leading cause of blindness after cataract. According to the National Eye Institute's report, there were almost 2.7 million detected cases in the United States in 2010.Everybody older than 40, African Americans and Hispanics at any age, are at high risk and would need frequent IOP measurement in order to diagnose the disease at an early stage. Majority of the existing tonometers measure the IOP through the cornea and their operation requires clinical professionals. As a result, the measurement has to take place at the doctor's office and requires local anesthesia. This work demonstrates a novel multi-probe tactile-tonometer, which is operated by the patients and measures the IOP through their eyelid. Finite element (FE) models were used to estimate the static, mechanical response of the eye, due to indentation at different IOPs. The models include hyperelastic behavior of the sclera and cornea. The thickness variation of the sclera, throughout the geometry was also considered. Volumetric constraint was applied on the eye cavity, but its actual anatomic structure was neglected. In-vitro indentation tests were performed on enucleated porcine eyeballs, as a proof of concept of tactile-tonometry. Eye/patient specific calibration method was demonstrated, in order to further improve accuracy ("Forward Biomechanics"), and in-vivo estimation of biomechanical properties of the eye ("Inverse Biomechanics"). The method uses simplified FE models and a feed forward artificial neural network (ANN). The tactile-tonometer was implemented for human use, and clinical studies were performed on a small number (10) of human subjects. Based on the measurements from the recruited 10 patients (3 females, 7 males) with a mean age ±SD of 43±19.33 and the measured IOP range of 9.25-21.25mmHg, the novel technique has a mean of differences of ≈ 0mmHg and its 95% limits of agreement are ±4.84mmHg with respect to the Goldmann Applanation Tonometer.

Abstract:

Early life history in marine benthic crustaceans often includes externally brooded eggs that hatch into free-swimming planktonic larvae. These larvae are relatively strong swimmers, and movement in the vertical plane provides a number of advantages, including modulation of horizontal transport and assurance of favorable predator–prey interactions. Swimming behavior in larval crustaceans is regulated by predictable external cues in the water column, primarily light, gravity, and hydrostatic pressure. Light-regulated behavior depends upon the optical physics of seawater and the physiology of light-detecting sensory structures in the larvae, which overall vary little with ontogeny. Swimming in response to light contributes to ecologically significant behaviors in planktonic crustacean larvae, including shadow responses, depth regulation, and diel vertical migration. Moreover, the photoresponses themselves, and in turn the evoked behaviors, change with the needs of larvae as development progresses. Regarding other sensory modalities, crustacean embryos and larvae respond to chemical cues using bimodal sensilla (chemosensory and mechanosensory) as contact receptors, and aesthetascs for detection of water-soluble cues. Processes and behaviors are stimulated by larval detection of chemical cues throughout ontogeny, including egg-hatching, avoidance of predators during free-swimming stages, and, ultimately, settlement and metamorphosis in juvenile habitats. The latter process can also involve tactile cues. The sensory-mediated behaviors described here for crustacean larvae have parallels in numerous arthropod and nonarthropod taxa. Emerging directions for future research on sensory aspects of behavior in crustacean larvae include multimodal sensory integration and behavioral responses to changing environmental stressors.

Abstract:

A condition for the effectiveness of sensory development of primary school students is a critical study of the pedagogical experience of its organization. The importance of solving this problem is caused by the fact that school practice lays the foundation of pedagogical science and must take into account both modern scientific achievements and requirements of regulatory state documents. The purpose of the study is to highlight the mass pedagogical experience of sensory development of primary school students. To achieve this goal, written and oral interviews with teachers (questionnaires, interviews, talks) and observation of professional activities were used. It has been revealed that teachers are aware of the meaning of sensory development and distinguish its leading areas – the forming of vision, hearing and touch of schoolchildren; identify students’ typical difficulties in distinguishing mixed colors, complex shapes of objects, sonorous, hissing and whistling consonants, as well as in reproducing the nuances of coloring of objects, the relationship between size and spatial arrangement, inclined and rounded elements of letters, sequence of sounds in an audible word. At the same time, teachers are poorly oriented in the program material of perceptual development, admit insufficient awareness of the laws of sensory processes, and want to know more about the latest techniques and technologies of their forming. Observation of the real educational process allowed to establish a wide range of didactic influences used by educators in order to form different types of students’ perception. Teachers organize studies of colored objects, correcting children's verbal designations of colors and their shades; suggest exercises for superimposing objects of different shapes and sizes (arranging by size, placing figures in given proportions, etc.); form students' ideas about speech sounds (observation of the work of speech organs, modeling the properties of sounds with conditional chips, analysis of the phonetic structure of words, etc.); provide perception of musical works, demonstrate sounds of musical instruments and singing voices, use symbols to record the gradations of sounds in pitch, duration and volume, encourage students to reproduce the properties of musical sounds in singing and rhythmic movements; create conditions for touching objects made of different materials. However, teachers do not pay enough attention to distinguishing and naming color nuances, three-dimensional geometric shapes, symbols of voicedness and voicelessness of consonants, comparison of musical sounds by timbre qualities, and verbal characteristics of tactile sensory impressions. The conducted research proves that the mass pedagogical experience ensures the implementation of program requirements for improving the sensory sphere of primary school students, but shows a lack of teachers’ awareness of children's sensory processes and unstable motivation to solve problems of developing students’ perception. The prospect for further scientific research is to study the program, educational and methodological resources of forming the processes of perception in primary school students.

Abstract:

Abstract Adding sensing capability to a robot provides the robot with intelligent perception capability and flexibility of decision making. To perform intelligent tasks, robots are highly required to perceive their operating environment, and react accordingly. With this regard, tactile sensors offer to extend the scope of intelligence of a robot for performing tasks which require object touching, recognition, and manipulation. This paper presents the design of an inexpensive pneumatic binary-array tactile sensor for such robotic applications. The paper describes some of the techniques implemented for object recognition from binary sensory information. Furthermore, it details the development of software and hardware which facilitate the sensor to provide useful information to a robot so that the robot perceives its operating environment during manipulation of objects.

Abstract:

An electromagnetic micro-actuator operating on the principle of voice-coil actuators is presented. Using finite element analysis of several conceptual designs of actuators [1–3], it was established that the voice-coil type device (where the coil is the moving part) has most beneficial characteristics for the envisioned application. These include sufficient force over a relatively large distance, allowing tactile stimulation of surfaces with irregular shape, fast response, and small footprint that matches the density of the tactile sensory neurons in the finger. Finite element analysis based on ANSYS was used to determine the dimensions of the components of the actuator. In comparison to earlier designs [3–5], this novel device has smaller sizes (2.28 mm in diameter and 7 mm in length), which makes it suitable for use in an array to be worn on the fingertip. Based on the static measurements of a test prototype, it is estimated, that the micro-actuator can produce at least 26 mN of repulsive force on the fingertip over a stroke of 2100 μm with a peak force of 34 mN. The driving circuit operates with 13.5V and generates a vibration frequency of up to 265 Hz without significant change of the force-displacement characteristics. In the higher frequency range (above 100 Hz) the actuator provides at least 15 mN of force over a stroke of 2300 μm, and a peak force of 21mN. The perceivability of the device on human fingertip approves the expectations drawn from the fact that all of the above parameters meet the required values of the thresholds of the human perception known from [4] and [5]. Due to its increased stroke, the voice-coil micro-actuator proved to be very suitable for the envisioned application allowing contact with the curved surface of the fingertip.

Abstract:

The importance of Human-Centered Design (HCD) drives research toward the development of new UIs (User Interfaces) in order to predict human interaction with products at the early design stages. Virtual Reality (VR) allows carrying out usability tests on virtual prototypes to investigate users’ cognitive and affective response. Application problems regard with the reproduction of synaesthesia qualities in order to make the information processing similar to the one obtained by real sensory stimulation. While visualization technologies seem to be mature enough to overcome the above mentioned limitation, tactile devices are still far from properly simulating materials properties. In this context, the present work aims at structuring and applying a systematic approach to conceive, define and develop a novel VR-based technology, called I-perTouch. The goal is to stimulate the skin mechanoreceptors to generate a meaningful tactile sensation about materials softness, friction and roughness. The system can be also integrated with imaging and sound technologies to create a multi-sensorial product experience. The preliminary architecture results from the analysis of human tactile perception and the benchmark of available simulation devices and techniques. This paper contributes to discuss current issues of existing VR-based technologies in supporting HCD applications and to address technical developments toward the creation of a reliable system for texture perception.

Abstract:

This article describes a novel method of indirect estimation of intra-ocular pressure using tactile sensors. Two sensor calibration methods have been demonstrated: an artificial neural network (ANN) model and a phenomenological reduced-parameter model based on finite element analysis. The ANN method showed superior performance with an accuracy of +/− 0.7 mmHg, while the reduced order method showed an accuracy of +/− 3.11 mmHg. The latter method however allows calibration of the tactile tonometer from a single pressure measurement if the geometry of the probes is known and satisfying certain solvability conditions. The ANN method was demonstrated using experiment data, while the reduced-order model was tested numerically. Due to its indirect and non-invasive nature, the proposed tactile measurement method can be used in the development of a self-administered home tonometer for management of glaucoma, however the presence of an eye lid might require modification of the calibration procedure outlined here.

Abstract:

In recent years, surgical assisting robots and nursing care robots are being introduced to medical and nursing fields due to the rapid increase of the aging society. In order to assure the safety and reliability of these robots, a highly sensitive tactile sensor is necessary to detect the state of contact between these robots and human body. The target specifications of this sensor are spatial resolution of less than 1 mm, and the pressure sensitivity of less than 10 kPa. Since the tactile sensor is expected to be attached on the tip of a surgical assisting robot or the arm of a nursing care robot, it should be small and flexible and highly sensitive to contact pressure. In this study, high quality MWCNT (Multi-Wall Carbon Nanotube) has been synthesized to develop two types of tactile sensors which consisted of a MWCNT film and the area-arrayed MWCNT bundles. Thermal CVD (Chemical Vapor Deposition) method was applied to the growth of MWCNT and PDMS (Polydimethylsiloxane) was used for a flexible substrate. It was found that MWCNT bundles showed elastic deformation in the compressive strain range from 0% to 60%. The PDMS substrate showed elastic deformation under the application of bending strain of about 20%. In addition, it was confirmed that the detecting resolution of the force was lower than 1 mN, and the obtained gauge factor of the developed sensor was about 3.5.

Abstract:

Alfenol (FexAl100−x) is an alloy similar to Galfenol (Fe-Ga alloys) in crystal lattice structure and magnetostriction trend (peaking at ∼20% composition). Although single-crystal Fe80Al20 exhibits lower magnetostriction (∼184 ppm, about half of Fe80Ga20), its magneto-elastic coupling coefficient is on par with that of Fe-Ga. In addition, characteristics such as machinability and rollability are superior to that of Galfenol, making it possible to achieve textured sheets (thickness∼200 μm) which, while having a high elastic modulus, are very flexible. Furthermore, Aluminum is non toxic, cheap (∼1% the cost of Ga) and is available in abundance. These attributes make Alfenol an ideal candidate for a bio-inspired whisker-like tactile sensor (mimicking mystacial vibrissae of cats, sea lions, etc.). This work deals with the design and development of an accurate, cost efficient, real-time, and non-invasive sensor prototype that tracks displacements, vibrations and scour on bridge piers with minimal signal conditioning. Making such a sensor is possible thanks to Alfenol’s linear response to strain in the presence of appropriate bias magnets. The change in its magnetic state due to inverse magnetostriction from applied bending stresses will be observed using Hall Effect sensors to derive deflection information. A protocol to manufacture rolled and textured Alfenol whisker samples will be presented in this research. The effect of bias conditions on sensor performance will be studied empirically and by using multi-physics simulations. Optimization of the sensor by varying the dimensions of the whisker, and its correlation to flux leakage will also be examined followed by an effort to understand the micro-magnetic response of Alfenol to mechanical stimulation. Finally, results from using this biomimetic sensor to measure displacements and vibrations, and its viability to be used as a flow sensor will be discussed. The robustness of this sensor has been exploited to develop a novel real-life application to provide an early warning system for bridge pier scour due to soil transportation during a weather event. The effectiveness of these sensors for scour detection in riverbeds will subsequently be simulated in a water flume and analyzed.
