Abstract:
A novel piezoelectric accelerometer with switch characteristic was introduced. The accelerometer is composed of top head, cross elastic beam, base core, insulation cylinder, mass block, piezoelectric elements, and the base etc. The accelerometers structure and operating principle were presented and its mathematic model was established. Test results show that the accelerometer can filter out high frequency vibration signal, which the out signal is smooth compared with the conventional piezoelectric accelerometer, furthermore with good linearity. It can be used in the smart fuze to take the place of conventional piezoelectric accelerometer in order to recognize the target accurately.

Abstract In this article, reconstructed displacement from the self-mixing signal is compared with the displacement obtained by the ceramic shear mode design piezoelectric accelerometer. Piezoelectric accelerometers are widely accepted due to the low output noise and wide frequency range, but nevertheless it is not contact-free. Self-mixing interferometric signals due to the vibrating target on which an accelerometer is attached are acquired by an external silicon type photodetector. The laser light hits directly the accelerometer as a target which is driven by the sum of two different sinusoidal frequencies of 150 and 300 Hz with different voltage levels.

Abstract:
Microelectromechanical (MEMS) piezoelectric accelerometers are diversely used in consumer electronics and handheld devices due to their low power consumption as well as simple reading circuit and good dynamic performance. In this paper, a tri-axial piezoelectric accelerometer with folded beams is presented. The four beam suspensions are located at two sides of the mass aligned with edges of the mass, and the thickness of the beams is the same as the thickness of the mass block. In order to realize the multi-axis detection, a total of 16 sensing elements are distributed at the end of the folded beams. The structural deformations, stress distribution, and output characteristics due to the acceleration in x-, y-, and z-axis directions are theoretically analyzed and simulated. The proposed accelerometer is fabricated by MEMS processes to form Mo/AlN/ScAlN/Mo piezoelectric stacks as the sensing layer. Experiments show that the charge sensitivity along the x-, y-, and z-axes could reach up to ~1.07 pC/g, ~0.66 pC/g, and ~3.35 pC/g. The new structure can provide inspiration for the design of tri-axial piezoelectric accelerometers with great sensitivity and linearity.

Abstract:
Miniaturized accelerometers are necessary for evaluating the performance of small devices, such as haptics, robotics and simulators. In this study, we fabricated miniaturized accelerometers using well-aligned ZnO nanowires. The layer of ZnO nanowires is used for active piezoelectric layer of the accelerometer, and copper was chosen as a head mass. Seedless and refresh hydrothermal synthesis methods were conducted to grow ZnO nanowires on the copper substrate and the effect of ZnO nanowire length on the accelerometer performance was investigated. The refresh hydrothermal synthesis exhibits longer ZnO nanowires, 12 µm, than the seedless hydrothermal synthesis, 6 µm. Performance of the fabricated accelerometers was verified by comparing with a commercial accelerometer. The sensitivity of the fabricated accelerometer by the refresh hydrothermal synthesis is shown to be 37.7 pA g −1 , which is about 30 times larger than the previous result.

Abstract:
In this paper, we report a novel aluminum nitride (AlN) thin-film piezoelectric resonant accelerometer. Different from the ordinary MEMS (micro-electro-mechanical systems) resonant accelerometers, the entire structure of the accelerometer, including the mass and the springs, is excited to resonate in-plane, and the resonance frequency is sensitive to the out-plane acceleration. The structure is centrosymmetrical with serpentine electrodes laid on supporting beams for driving and sensing. The stiffness of the supporting beams changes when an out-plane inertial force is applied on the structure. Therefore, the resonance frequency of the accelerometer will also change under the inertial force. The working principle is analyzed and the properties are simulated in the paper. The proposed AlN accelerometer is fabricated by the MEMS technology, and the structure is released by an ICP isotropic etching. The resonance frequency is 24.66 kHz at a static state. The quality factor is 1868. The relative sensitivity of this accelerometer, defined as the shift in the resonance frequency per gravity unit (1 g = 9.8 m/s2) is 346 ppm/g. The linearity of the accelerometer is 0.9988. The temperature coefficient of frequency (TCF) of this accelerometer is −2.628 Hz/°C (i.e., −106 ppm/°C), tested from −40 °C to 85 °C.

Abstract:
Le misure vibrazionali sono un punto di riferimento nella dinamica strutturale. Lo stesso vale anche per la diagnostica dei guasti e la valutazione della qualità del prodotto in vari campi dell'industria, dalle linee di produzione dei componenti ai prodotti finiti. Queste misure sono solitamente eseguite utilizzando accelerometri piezoelettrici collegati alla struttura in esame. Il collegamento è solitamente realizzato tramite adesivi o cera d'api, magneti o perni filettati. Tuttavia, il processo di installazione di questi sensori può richiedere molto tempo e, in alcuni casi, può essere irreversibile o addirittura non consentito. Le sonde vibrazionali di tipo hand-held sono state ampiamente utilizzate in passato, anche se le loro prestazioni (ad es. gamma di frequenze di lavoro e accuratezza complessiva) risultano inferiori rispetto alle installazioni fisse. Tuttavia, la diffusione dei robot nell'ambito dell'industria 4.0, caratterizzata dall'obiettivo di produzione a zero difetti, ha motivato un nuovo interesse per questo tipo di soluzione. Le sonde di misura vibrazionali tipo hand-held sono costituite da componenti che devono garantirne la linearità entro un determinato intervallo di frequenza e il contatto costante con la struttura in prova. Inoltre, le vibrazioni spurie, dovute alla manipolazione da parte di un operatore umano o di un robot, devono essere evitate introducendo un elemento di disaccoppiamento. Normalmente, vengono impiegati materiali convenzionali come la gomma e il silicone, per via del loro comportamento viscoelastico. Tuttavia, questi materiali possono subire modifiche al loro comportamento dinamico quando soggetti a condizioni ambientali diverse. Lo scopo di questa tesi è dimostrare il vantaggio nell'adottare metastrutture come elementi di disaccoppiamento nelle sonde vibrazionali di tipo hand-held. La metastruttura sviluppata si basa su una ripetizione periodica di celle unitarie caratterizzate da una forte separazione modale. Ne consegue, quindi, un ampio intervallo di frequenze di funzionamento.
Vibrational measurements are a landmark in structural dynamics. This is true also for fault diagnosis and product quality assessment in various fields of industry, from production lines of components to finite products. These measurements are usually performed using piezoelectric accelerometers attached to the structure under investigation. The connection is usually made using adhesive or bees-wax, magnets or threaded pins. However, the process of installing these sensors can be time-consuming and, in some cases, irreversible or even not allowed. Hand-held vibration probes were widely used in the past, even though their performances (i.e. working frequency range and overall accuracy) were lower compared to fixed installations. However, the spread of robots in the framework of industry 4.0, characterized by the zero defect manufacturing target, caused a new interest in this solution. Hand-held vibration measurements probes are made of components that must guarantee linearity within certain frequency range as well as constant contact with the structure being tested. Furthermore, spurious vibrations, due to the handling by a human operator or a robot, need to be avoided introducing a decoupling element. Normally, conventional materials, like rubber and silicon, are exploited, taking advantage of their viscoelastic behavior. However, these materials may undergo changing on their dynamic behavior when subject to different environmental conditions. The aim of this thesis is to demonstrate de advantage of adopting metastructures as decoupling elements in hand-held probes. The design of the metastructure developed is based on a periodic repetition of unit cells characterized by a strong mode separation and, thus, a wide frequency bandgap.

Abstract:
This diploma thesis deals with the possibility of vibration sensing and vibrodiagnostics based on the use of so-called "SMART" materials such as piezoelectric layers or structures. Research studies have examined the general overview of vibrodiagnostic methods and their analysis of the possibility of sensing vibration by piezoelectric structures. This was followed by measuring and evaluating the results using various vibro-diagnostic methods. The results were compared with those obtained by sensing vibration using an accelerometer. We also dealt with the problem of detecting the deformation of the device by sensing vibration with piezoelectric structures. The last part was programming the "Myrio" to capture and evaluate the vibration using Labview.

En vue de la realisation de capteurs accelerometriques, nous avons etudie les proprietes du pvf2 et nous avons analyse le comportement d'une lame de pvf2 soumise a une contrainte de compression. Nous avons developpe des modeles electriques du pvf2 qui nous permettent d'effectuer des simulations a l'aide du logiciel spice. Ces modeles nous ont permis de definir les caracteristiques theoriques de nos capteurs que nous avons pu correler avec les resultats experimentaux. A la suite de ces etudes theoriques nous avons realise des capteurs accelerometriques. Parmi ceux-ci nous retiendrons l'accelerometre sismique et le capteur d'activite. Ces deux capteurs sont interessants car ils presentent des caracteristiques extremes, tant sur le plan metrologique que sur le plan dimensionnel. Enfin, nous avons aussi a partir des etudes faites sur les caracteristiques des accelerometres a masses inertielles developpe un capteur gyrometrique susceptible de delivrer des signaux proportionnels aux grandeurs liees a un mouvement de rotation. En nous basant sur les travaux de modelisation, nous avons explore le domaine des basses frequences.

Abstract:
The widespread use of vehicles has led to an increase in traffic accidents. In these accidents, motorcyclists are exposed to more risks because they are more vulnerable than car drivers. With the development of technology, manufacturers have increased their work on vehicle security systems. Advancements in these studies which are being applied in daily life resulted in a reduction of risks in accidents. In this thesis, Zero-Power Fall Detection System is developed for smart helmets, which is a safety system for motorcycles. Since the lifetime of electronic devices has become one of the most important features of today, the aim of this study is to design a self-sustainable fall detection system that consumes as low power as possible. First, the system is designed with Piezoelectric Wake-up Circuits, a microcontroller unit with bluetooth low energy communication and a self-sustainable battery management system with high efficiency power recovery. Then, a fall detection algorithm is designed to send a message to a smartphone, tablet or etc. through bluetooth low energy connection when hazardous situations are detected. Based on this algorithm, the software of the system is prepared. Finally, field tests have been carried out and according to the results, it has been shown that the fall detection system developed is functional and has a very low power consumption.

This work presents contributions to the sinusoidal acceleration control of electrodynamic shakers applied in vibration testing. Considering the importance of sine tests to identify critical frequencies of operation and to determine mechanical weakness in the specified performance of specimens, vibration controllers are designed to reproduce the amplitude and the frequency of the reference acceleration specifically at the interface between the shaker and the structure under test. Two distinct approaches are considered to solve the control problem: time domain control, where the acceleration instantaneous value is adjusted to track the sinusoidal reference, and frequency domain control, in which only the amplitude or the root mean square value of the acceleration is compensated to follow the reference magnitude. The solutions developed based on these two different approaches are implemented in a digital control platform and experimentally evaluated. The development of vibration controllers is complemented by contributions to the study of the shaker dynamic model, as well as to the instrumentation applied to measure and feedback the acceleration and to the voltage control of switching-mode power amplifiers designed to drive the shaker. Regarding the vibration machine dynamic model, a method is proposed to experimentally identify the mechanical parameters of a two degrees of freedom system that represents the suspension resonance and the finite armature stiffness of the electrodynamic shaker. A procedure is developed to design and implement charge mode preamplifiers and signal conditioning circuits for piezoelectric accelerometers. A robust model reference adaptive algorithm is applied to control the output voltage of an industrial switching-mode power amplifier. The experimental analysis of the adaptive controller considers not only the improvements on the power amplifier performance, but also the of impact over the behavior of a commercial digital vibration control system.
Este trabalho apresenta contribuições ao controle de aceleração senoidal de vibradores eletrodinâmicos utilizados em ensaios de vibração. Considerando a importância de testes com aceleração senoidal para identificar freqüências críticas de operação e determinar a resistência de materiais e estruturas, são desenvolvidos controladores para a máquina de vibração com o propósito de garantir que a amplitude e a freqüência da aceleração imposta à estrutura sob teste correspondam aos valores de referência. Na solução do problema, admitem-se duas abordagens distintas: controle no domínio do tempo, onde o valor instantâneo da aceleração é ajustado para seguir a referência senoidal, e controle no domínio da freqüência, no qual apenas a amplitude ou o valor eficaz da aceleração é regulado conforme a magnitude de referência. As técnicas propostas com base nestas abordagens são implementadas numa plataforma de controle digital e avaliadas experimentalmente. O desenvolvimento dos controladores de vibrações é complementado por contribuições ao estudo do modelo dinâmico do vibrador, à instrumentação aplicada para realimentar a aceleração e ao controle da tensão de amplificadores de potência que utilizam inversores com modulação por largura de pulso para acionar a máquina. Com relação ao modelo do vibrador, é descrito um método que permite determinar experimentalmente os parâmetros mecânicos de um modelo com dois graus de liberdade, o qual representa o comportamento da máquina devido à suspensão e à rigidez finita da armadura. Um procedimento de projeto e realização prática de pré-amplificadores de carga e de um circuito de condicionamento para acelerômetros piezoelétricos é apresentado. Um algoritmo adaptativo robusto por modelo de referência é avaliado no controle da tensão de saída de um amplificador industrial projetado para excitar o enrolamento da armadura do vibrador. A análise experimental do impacto do controlador adaptativo é realizada considerando não apenas a melhoria no desempenho do amplificador, mas também em termos dos reflexos na performance de uma plataforma comercial de controle de ensaios de vibrações.

This work presents the development of a novel digital acceleration controller for sinusoidal vibration tests using switching-mode AC power source (ACPS) fed electrodynamic vibration machines. The proposed scheme is based on the interaction of two control loops: one for the shaker's acceleration regulation and another for the ACPS output voltage control. A robust model reference adaptive algorithm (RMRAC) is used in the voltage control loop. To reduce the effects caused by the plant's parameters variations as well harmonic vibrations and resonances of the test specimen, the acceleration feedback controller is augmented with a feedforward and a robust controller. Experimental results show that the proposed system is capable to achieve excellent acceleration reference tracking performance and robustness in the closed loop control from 20 Hz to 200 Hz. Investigations shall be performed to evaluate the response of this scheme when controlling vibrations as fast as 2000 Hz. A specific instrumentation system has been developed to feedback the electrodynamic vibration machine's acceleration. The proposed solution employs piezoelectric accelerometers, voltage mode preamplifiers, circuit for signal conditioning, analog to digital conversion and filtering. A study concerning the commonly used vibration measurement techniques and the design procedure, simulation, implementation and experimental results are described in detail.
Esse trabalho apresenta o desenvolvimento de um novo tipo de controlador digital de aceleração para ensaios com vibrações senoidais em máquinas de vibra ção eletrodinâmicas supridas por fontes de potência CA com comutação. O esquema proposto é baseado na interação entre duas malhas de controle: uma para regulação de aceleração da máquina de vibração e outra para ajuste da tensão de saída da fonte de potência CA. Um algoritmo adaptativo robusto por modelo de referência (RMRAC) é utilizado na malha de controle de tensão. Os efeitos de variações paramétricas existentes na planta bem como de vibrações harmônicas e ressonâncias do objeto ensaiado são minimizados com o uso de um controlador feedforward e um controlador feedforward robusto na malha de aceleração. Resultados experimentais demonstram que o sistema proposto é capaz de garantir excelente rastreamento da aceleração de referência e robustez em malha fechada entre 20 Hz e 200 Hz, necessitando ainda de investigação para controle de vibrações tão rápidas quanto 2000 Hz. A realimentação da aceleração da máquina é realizada com o desenvolvimento de uma instrumentação adequada a esse fim. A solução proposta utiliza acelerômetros piezoelétricos, pré-amplificadores modo tensão, circuito para condicionamento de sinais, conversão analógico-digital e filtragem.

Abstract:
Significant advances in wind turbine technology have increased the need for maintenance through condition monitoring. Indeed condition monitoring techniques exist and are deployed on wind turbines across Europe and America but are limited in scope. The sensors and monitoring devices used can be very expensive to deploy, further increasing costs within the wind industry. The work outlined in this thesis primarily investigates potential low-cost alternatives in the laboratory environment using vibration-based and modal testing techniques that could be used to monitor the condition of wind turbine blades. The main contributions of this thesis are: (1) the review of vibration-based condition monitoring for changing natural frequency identification; (2) the application of low-cost piezoelectric sounders with proof mass for sensing and measuring vibrations which provide information on structural health; (3) the application of low-cost miniature Micro-Electro-Mechanical Systems (MEMS) accelerometers for detecting and measuring defects in micro wind turbine blades in laboratory experiments; (4) development of an in-service calibration technique for arbitrarily positioned MEMS accelerometers on a medium-sized wind turbine blade. This allowed for easier aligning of coordinate systems and setting the accelerometer calibration values using samples taken over a period of time; (5) laboratory validation of low-cost modal analysis techniques on a medium-sized wind turbine blade; (6) mimicked ice-loading and laboratory measurement of vibration characteristics using MEMS accelerometers on a real wind turbine blade and (7) conceptualisation and systems design of a novel embedded monitoring system that can be installed at manufacture, is self-powered, has signal processing capability and can operate remotely. By applying the conclusions of this work, which demonstrates that low-cost consumer electronics specifically MEMS accelerometers can measure the vibration characteristics of wind turbine blades, the implementation and deployment of these devices can contribute towards reducing the rising costs of condition monitoring within the wind industry.

Abstract:
Traditional piezoelectric accelerometers used for machine condition monitoring are expensive and represent a capital risk when placed in the harsh environment of a cutting process. Additionally, these components require signal conditioning hardware and are sampled on a PC via an independent data acquisition interface (DAQ card). The goal of the research discussed herein is to test an industrial-friendly electret-based accelerometer that can perform tasks similar to a traditional piezoelectric accelerometer. The sensor will be adapted to utilize Bluetooth wireless data capabilities, further enhancing the sensors industrial practicality. The output of this electret-based sensor will be compared to the output of a traditional piezoelectric accelerometer and accompanying DAQ. More specifically, the study will focus on the effects of elevated temperature on the sensor. To achieve this, a comparison of both the electret and piezoelectric accelerometer response spectra will be observed over a range of 21°C to 77°C. To further validate the sensor, turning data is collected wirelessly from the sensor and compared to the output of the traditional piezoelectric sensor. Finally, the performance of the sensor for monitoring a tool’s condition during turning is evaluated and presented. The generated trend is contrasted to the comparable trend developed from the piezoelectric-based accelerometer.
