Abstract:

Three-dimensional (3D) printing is a promising manufacturing platform in biomedical engineering. It offers significant advantages in fabricating complex and customized biomedical products with accuracy, efficiency, cost-effectiveness, and reproducibility. The rapidly growing field of three-dimensional printing (3DP), which emphasizes customization as its key advantage, is actively searching for functional materials. Among these materials, piezoelectric materials are highly desired due to their linear electromechanical and thermoelectric properties. Polymer piezoelectrics and their composites are in high demand as biomaterials due to their controllable and reproducible piezoelectric properties. Three-dimensional printable piezoelectric materials have opened new possibilities for integration into biomedical fields such as sensors for healthcare monitoring, controlled drug delivery systems, tissue engineering, microfluidic, and artificial muscle actuators. Overall, this review paper provides insights into the fundamentals of polymer piezoelectric materials, the application of polymer piezoelectric materials in biomedical fields, and highlights the challenges and opportunities in realizing their full potential for functional applications. By addressing these challenges, integrating 3DP and piezoelectric materials can lead to the development of advanced sensors and devices with enhanced performance and customization capabilities for biomedical applications.

Abstract:

Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric materials must have a noncentrosymmetric crystal structure. For more than a century, this has remained a major obstacle for finding piezoelectric materials. We circumvented this limitation by breaking the crystallographic symmetry and inducing large and sustainable piezoelectric effects in centrosymmetric materials by the electric field–induced rearrangement of oxygen vacancies. Our results show the generation of extraordinarily large piezoelectric responses [with piezoelectric strain coefficients ( d 33 ) of ~200,000 picometers per volt at millihertz frequencies] in cubic fluorite gadolinium-doped CeO 2− x films, which are two orders of magnitude larger than the responses observed in the presently best-known lead-based piezoelectric relaxor–ferroelectric oxide at kilohertz frequencies. These findings provide opportunities to design piezoelectric materials from environmentally friendly centrosymmetric ones.

Abstract:

The development of new materials and the performance improvement of existing materials become an important subject from different aspects. In this paper, based on the theoretical research results of multiple piezoelectric effects, the influence of multiple piezoelectric effects on elastic coefficient of piezoelectric ceramics is studied. Theoretical analysis indicates that it is multiple piezoelectric effects that make piezoelectrics have two kinds of elastic and they result in the decrease of elastic compliance coefficients. Experimental validation is performed through PZT-5. Experimental results show that elastic compliance coefficient grows decreased by 0.912 times.

Abstract:

Piezoelectronics, as an efficient approach for energy conversion and sensing, have a far-reaching influence on energy harvesting, precise instruments, sensing, health monitoring and so on. A majority of the previous works on piezoelectronics concentrated on the materials that are applied at close to room temperatures. However, there is inadequate research on the materials for high-temperature piezoelectric applications, yet they also have important applications in the critical equipment of aeroengines and nuclear reactors in harsh and high-temperature conditions. In this review, we briefly introduce fundamental knowledge about the piezoelectric effect, and emphatically elucidate high-temperature piezoelectrics, involving: the typical piezoelectric materials operated in high temperatures, and the applications, limiting factors, prospects and challenges of piezoelectricity at high temperatures.

Abstract:

Our 21st century faces to a “sustainable society”, which enhances (a) usage of non-toxic materials, (b) disposal technology for existing hazardous materials, (c) reduction of contamination gas, (d) environmental monitoring system, (e) new energy source creation, and (f) energy-efficient device development in the piezoelectric area. With reducing their size, the electromagnetic components reduce their efficiency drastically. Thus, piezoelectric transducers with much less losses are highly sought recently. Piezoelectric devices seem to be all-around contributors and a key component to the above mentioned five R&D areas. Some of the efforts include: (a) Since the most popular piezoelectric lead zirconate titante ceramics will be regulated in European and Asian societies due to their toxicity (Pb2+ ion), lead-free piezoelectrics have been developed. (b) Since hazardous organic substances can easily be dissolved by the ultrasonic irradiation in water, a new safe disposal technology using piezoelectric transducers has been developed. (c) We demonstrated an energy recovery system on a hybrid car from its engine’s mechanical vibration to the rechargeable battery. (d) Micro ultrasonic motors based on piezoelectrics demonstrated 1/20 reduction in the volume and a 20-time increase in efficiency of the conventional electromagnetic motors. This paper introduces leading piezoelectric materials, devices, and drive/control methods, relating with the above “sustainability” technologies, aiming at further research expansion in this area.

Abstract:

By using piezoelectric materials, it is possible to convert clean and renewable energy sources into electrical energy. In this paper, the effect on the piezoelectro-elastic response of piezoelectric-fiber-reinforced nanocomposites by adding silica nanoparticles into the polyimide matrix is investigated by a micromechanical method. First, the Ji and Mori–Tanaka models are used to calculate the properties of the nanoscale silica-filled polymer. The nanoparticle agglomeration and silica–polymer interphase are considered in the micromechanical modeling. Then, considering the filled polymer as the matrix and the piezoelectric fiber as the reinforcement, the Mori–Tanaka model is used to estimate the elastic and piezoelectric constants of the piezoelectric fibrous nanocomposites. It was found that adding silica nanoparticles into the polymer improves the elastic and piezoelectric properties of the piezoelectric fibrous nanocomposites. When the fiber volume fraction is 60%, the nanocomposite with the 3% silica-filled polyimide exhibits 39%, 31.8%, and 37% improvements in the transverse Young’s modulus ET, transverse shear modulus GTL, and piezoelectric coefficient e31 in comparison with the composite without nanoparticles. Furthermore, the piezoelectro-elastic properties such as ET, GTL, and e31 can be improved as the nanoparticle diameter decreases. However, the elastic and piezoelectric constants of the piezoelectric fibrous nanocomposites decrease once the nanoparticles are agglomerated in the polymer matrix. A thick interphase with a high stiffness enhances the nanocomposite’s piezoelectro-elastic performance. Also, the influence of volume fractions of the silica nanoparticles and piezoelectric fibers on the nanocomposite properties is studied.

Abstract:

The anisotropy that is inherent to piezoelectricity is directly tied to the symmetry of domains within the crystals of polycrystalline piezoelectrics. Alloy design for these oxide materials is often focused on influencing pinning of domain walls in polycrystals that have been subjected to high fields and elevated temperatures to introduce the ‘poled’ condition from which most piezoelectric devices operate. We have investigated a wide range of these oxides consisting of single phases or mixtures of phases that may be all or partially piezoelectric in character. Crystal symmetries investigated include tetragonal, orthorhombic, rhombohedral and monoclinic with some phase transitions evolving during high-temperature processing or during poling. Materials investigated include a range of bismuth titanates, lead titanates, lead zirconate titanates and sodium niobates. A variety of texture evaluation techniques, including area detector x-ray diffraction, synchrotron x-ray sources, and neutron sources have been utilized along with Rietveld diffraction modeling tools to enable a deeper understanding of domain textures, domain texture evolution and synergistic relations between crystallographic textures and domain textures. This paper documents an understanding of texture and anisotropy in these materials, and provides insight on approaches to optimize textures for high performance in these materials and demonstrates how these tools can be used to evaluate processing variations from production of these materials.

Abstract:

We analyze coupled flexural vibration of two elastically and electrically connected piezoelectric beams near resonance for converting mechanical vibration energy to electrical energy. Each beam is a so-called piezoelectric bimorph with two layers of piezoelectrics. The 1D equations for bending of piezoelectric beams are used for a theoretical analysis. An exact analytical solution to the beam equations is obtained. Numerical results based on the solution show that the two resonances of individual beams can be tuned as close as desired by design when they are connected to yield a wide-band electrical output. Therefore, the structure can be used as a wide-band piezoelectric power harvester.

Abstract:

Piezoelectric biosensors are a type of analytical equipment that works based on recording affinity interactions. A piezoelectric platform, also known as a piezoelectric crystal, is a sensor component that works on the premise of oscillations changing according to the presence of a mass on the piezoelectric crystal surface. Owing to their high piezoelectricity, biocompatibility, as well as different electrical properties, biomolecular piezoelectric materials are thought to be promising candidates for future piezoelectric biosensors. When biological components in the human body are stressed, they are estimated to produce electric fields that promote cell growth and repair. As a by-product, piezoelectricity research in biological tissues and their elements has drawn much attention recently. This article specifies the principle of the advancement in piezoelectricity research of representative biomolecular materials, which are nucleic acids such as amino acids (DNA, RNA), peptides, proteins, and viruses. We also explored the origins and processes of piezoelectricity in biomolecular materials for biosensor application. Various advantages of using piezoelectric biomolecular materials for biosensor applications are elaborated. Lastly, a comprehensive idea of future challenges and discussion are provided.

Abstract:

The world’s energy crisis and environmental pollution are mainly caused by the increase in the use of fossil fuels for energy, which has led scientists to investigate specific cutting-edge devices that can capture the energy present in the immediate environment for subsequent conversion. The predominant form of energy is mechanical energy; it is the most prevalent energy in the environment and can be harvested for conversion into useful, electrical energy. Compared with electromagnetic, electrostatic, magneto strictive, dielectric elastomer and frictional electric transducers, piezoelectric transducers have higher high electrical and mechanical constants, large electromechanical coupling coefficients, high dielectric numbers and low losses and are currently the most dominant method of mechanical energy acquisition. Therefore, the research of piezoelectric transducers has received great attention from the scientific community. This paper reviews the research progress of piezoelectric energy acquisition technology. The main objective of this paper is to compile, discuss and summarize the recent literature on piezoelectric energy harvesting materials and applications. Piezoelectric catalytic materials, piezoelectric supercapacitors (SCs), piezoelectric self-charging devices and piezoelectric electrochemical energy storage are mainly introduced. This review briefly introduces the recent advances in piezoelectric-based catalysts and electrochemical energy storage, concentrating on the attributes of various piezoelectric materials and their uses.

Abstract:

Piezoelectric materials are important for many physical and electronic devices. Although many piezoelectric ceramics exhibit good piezoelectricity, they often show poor compatibility with biological systems that limits their biomedical applications. Piezoelectric peptide and metabolite materials benefit from their intrinsic biocompatibility, degradability, and convenient biofunctionalization and are promising candidates for biological and medical applications. Herein, we provide an account of the recent progress of research works on piezoelectric peptide and metabolite materials. This review focuses on the growth mechanism of peptide and metabolite micro- and nanomaterials. The influence of self-assembly processes on their piezoelectricity is discussed. Peptide and metabolite materials demonstrate not only outstanding piezoelectric properties but also unique electronic, optical, and physical properties, enabling their applications in nanogenerators, sensors, and optical waveguiding devices.

Abstract:

Abstract In order to maximize the acquisition of vibration energy of a large mechanical shell, the piezoelectric oscillation energy collector model of a twin cantilever beam was built in COMSOL Multiphysics software by finite element analysis based on the piezoelectric effect. The influence of piezoelectric material, substrate material, and size of piezoelectric material in the output features of piezoelectric energy collector is studied. The research shows that the PZT-5 A output features the best maximum output voltage and power up to 5.2 V and 1.1 mW in the 60-80 Hz range with the highest power density. Based on the selection of PZT-5A using brass as the substrate, the output characteristics of the best maximum output power increased by 5% to 1.16 mW. Based on the selection of PZT-5A as the piezoelectric material and brass as the substrate material, the length, width, and height of PZT-5A were simulated. Finally, the length, width, and height of PZT-5A were determined to be (21×6×0.06) mm3. In this case, the maximum output voltage and power were 5.93 V and 1.31 mW, respectively, which increased by 14% and 19% compared with the initial structure model.

Abstract:

Piezoelectric materials, which can couple electrical and mechanical displacements, are one of the most important functional materials nowadays. They comprises piezoelectric monocrystals, piezoelectric polycrystals (piezoelectric ceramics), piezoelectric polymers, and piezoelectric composites. Sensors made of these materials can convert pressure, acceleration, flow rate, etc. to surface charge (voltage) that can be easily processed, and at the same time generate their own energy instead of consuming it. Compared to other electromechanical transduction technologies, piezoelectric sensors have the advantages of high environmental and chemical stability, broad temperature and frequency band, as well as self-sufficiency. Piezoelectric materials can also be used in various applications such as energy harvesters, actuators, transducers, and capacitors. This paper reviews the piezoelectric materials and their recent application progress on sensors and others. These published results show the developing trend of piezoelectric sensors to become lead-free, flexible, and with high performance.

Abstract:

Piezoelectric thin films are extensively used as sensing or actuating layers in various micro-electromechanical systems (MEMS) applications. However, most piezoelectrics are stiff ceramics, and current polymer piezoelectrics are not compatible with microfabrication due to their low Curie Temperature. Recent polymer-composite piezoelectrics have gained interest but can be difficult to pattern. Photodefinable piezoelectric films could resolve these challenges by reducing the manufacturability steps by eliminating the etching process. But they typically have poor resolution and thickness properties. This study explores methods of enhancing the manufacturability of piezoelectric composite films by optimizing the process parameters and synthesis of SU-8 piezo-composite materials. Piezoelectric ceramic powders (barium titanate (BTO) and lead zirconate titanate (PZT)) were integrated into SU-8, a negative epoxy-based photoresist, to produce high-resolution composites in a non-cleanroom environment. I-line (365 nm) light was used to enhance resolution compared to broadband lithography. Two variations of SU-8 were prepared by thinning down SU-8 3050 and SU-8 3005. Different weight percentages of the piezoelectric powders were investigated: 5, 10, 15 and 20 wt.% along with varied photolithography processing parameters. The composites’ transmittance properties were characterized using UV-Vis spectroscopy and the films’ crystallinity was determined using X-ray diffraction (XRD). The 0–3 SU-8/piezo composites demonstrated resolutions < 2 μm while maintaining bulk piezoelectric coefficients d33 > 5 pm V−1. The films were developed with thicknesses >10 μm. Stacked layers were achieved and demonstrated significantly higher d33 properties.

Abstract:

Active materials are a group of solid-state materials whose geometric shape can be related to an energy input in the form of heat, light, electric field, or magnetic field. In the application of active materials to electromechanical energy conversion, electrical energy may be input to the material and the resulting deformation of the material can be used to move a load. The most common active materials used in actuators are piezoelectrics, magnetostrictives, and SMAs. In this paper, a piezoelectric actuation concept is presented that uses a new feed-screw motion accumulation technique. The feed-screw concept involves accumulating high frequency actuation strokes of a piezoelectric stack (driving element) by intermittently rotating nuts on an output feed-screw. The main parts of piezoelectric actuation such as clamp mechanism, rotary mechanism and “L type” driving mechanism are investigated. From the analysis, the deformation and stress of it are all under allowed value of 65Mn. The mathematics model of upside of rotary mechanism rotation motion is established. The results indicate that, the mechanisms of actuator all are satisfy the need of design

Abstract:

The properties of piezoelectric materials due to the effect of electrical, mechanical, thermal, radiation, and chemical parameters are systematized. On the basis of Maxwell's relations (obtained from expressions for thermodynamic functions) and the application of the system analysis methodology, it made it possible to develop an analytical model of the relationship between the parameters and properties of piezoelectrics in the form of a system of equations. The results of the metrological analysis of an analytical model, which made it possible to identify the sources of additional errors in the measurement of parameters, to derive formulas for their calculation, which in turn contributes to an increase in the accuracy of measurements of the piezoelectrics parameters and products based on them, are presented.

Abstract:

The ANSYS finite element techniques were used for modeling and analysis of piezoelectric materials. The single piezoelectric sheet model was presented. The basic characteristic of the piezoelectric materials were analyzed and the affecting factors of characteristics were derived. The high frequency simulation results showed that the displacement responses of piezoelectric materials were very large delay in boost and buck under the high frequency voltage signal, and that was adverse to the vibration control. The low frequency voltage simulation results showed that the displacement response frequency and voltage signal frequency were exactly the same. The model thickness greatly affected its stiffness and indirectly affected its output characteristics.

Abstract:

Vibration sensor technology, particularly piezoelectric vibration sensors, is extensively utilized across various fields due to their excellent dynamic response, linearity, wide bandwidth, high sensitivity, large temperature range, simple structure, and stable performance. They are widely applied in sectors such as nuclear power, aerospace, rail transportation, and defense industries. However, most piezoelectric vibration sensors are limited to operating temperatures below 500 ℃, which restricts their use in extreme high-temperature environments encountered in nuclear reactors, aircraft engines, missile systems, and internal combustion engines. These application scenarios impose higher demands on the reliability of piezoelectric vibration sensors for long-term service in extreme environments. How to improve the operating temperature of piezoelectric vibration sensors to meet the application needs in extreme environments is currently an urgent problem to be solved.<br>High-temperature piezoelectric materials, as the core components of piezoelectric vibration sensors, play a decisive role in determining the overall performance of the sensor. Common high-temperature piezoelectric materials include piezoelectric ceramics and single crystals. To ensure stable operation and excellent sensitivity in extreme environments, it is essential to select piezoelectric materials with high Curie temperatures, high piezoelectric coefficients, high resistivity, and low dielectric losses as the sensing elements of the sensor. Piezoelectric vibration sensors typically come in three main types: bending, compression, and shear. In addition to selecting the appropriate piezoelectric material, it is also crucial to choose the optimal sensor structure tailored to the specific application scenario.<br>Based on the urgent demand for ultrahigh-temperature vibration sensors, this paper primarily reviews the current research progress on high-temperature piezoelectric materials and high-temperature piezoelectric vibration sensors, summarizes the structures, advantages and disadvantages, and application scenarios of different types of high-temperature piezoelectric vibration sensors, explores the current problems and future development trends of high-temperature piezoelectric vibration sensors, and provides ideas for developing the next generation of ultrahigh temperature vibration sensors for extreme environmental applications, which is expected to promote the further development of high-temperature piezoelectric vibration sensing technology.

Abstract:

Piezoelectric materials are a group of important functional building blocks that interfacing the human body by coupling biomechanical energy and electricity. So far, many technology innovations have advanced piezoelectric materials and composites toward a broad range of biomedical applications, which possess unique biocompatibility and flexibility. Fundamentally, materials design and engineering draw the boundary where this technology may advance. In this talk, I introduce our most recent development of piezoelectric materials and composites that are particularly designed for implantable nanogenerator applications. First, I present our wafer-scale approach to creating piezoelectric biomaterial thin films based on γ glycine crystals. The self-assembled sandwich film structure enabled both strong piezoelectricity and largely improved flexibility. Then, new ferroelectric composites are presented as a new material used in 3D printing for directly manufacturing of piezoelectric architectures with tunable piezoelectric and mechanical properties. Toward the end, novel applications of implantable piezoelectric materials are introduced, which enable the closed-loop electrostimulations for many biomedical therapeutics.

Abstract:

This paper examines the selection and performance evaluation of a variety of piezoelectric materials for cantilever-based sensor applications. The finite element analysis method is implemented to evaluate the relative importance of materials properties such as Young's Modulus (E), piezoelectric stress constants (e31), dielectric constant (ε) and Poisson's ratio (υ) for cantilever-based sensor applications. An analytic hierarchy process (AHP) is used to assign weights to the properties that are studied for the sensor structure under study. A technique for order preference by similarity to ideal solution (TOPSIS) is used to rank the performance of the piezoelectric materials in the context of sensor voltage outputs. The ranking achieved by the TOPSIS analysis is in good agreement with the results obtained from finite element method simulation. The numerical simulations show that K 0.5 Na 0.5 NbO 3– LiSbO 3 (KNN–LS) materials family is important for sensor application. Young's modulus (E) is most influencing material's property followed by piezoelectric constant (e31), dielectric constant (ε) and Poisson's ratio (υ) for cantilever-based piezoelectric sensor applications.

Abstract:

Piezoelectric biomaterials can generate piezoelectrical charges in response to mechanical activation. These generated charges can directly stimulate bone regeneration by triggering signaling pathway that is important for regulating osteogenesis of cells seeded on the materials. On the other hand, mechanical forces applied to the biomaterials play an important role in bone regeneration through the process called mechanotransduction. While mechanical force and electrical charges are both important contributing factors to bone tissue regeneration, they operate through different underlying mechanisms. The utilizations of piezoelectric biomaterials have been explored to serve as self-charged scaffolds which can promote stem cell differentiation and the formation of functional bone tissues. However, it is still not clear how mechanical activation and electrical charge act together on such a scaffold and which factors play more important role in the piezoelectric stimulation to induce osteogenesis. In our study, we found Poly(l-lactic acid) (PLLA)-based piezoelectric scaffolds with higher piezoelectric charges had a more pronounced osteoinductive effect than those with lower charges. This provided a new mechanistic insight that the observed osteoinductive effect of the piezoelectric PLLA scaffolds is likely due to the piezoelectric stimulation they provide, rather than mechanical stimulation alone. Our findings provide a crucial guide for the optimization of piezoelectric material design and usage.

Abstract:

In this study, structural vibration control using semi-active shunt piezoelectric damping circuits is presented. A piezoelectric patch with an electrical shunt circuit is bonded to a base structure. When the structure vibrates, the piezoelectric patch strains and transforms the mechanical energy of the structure into electrical energy, which can be effectively dissipated by the shunt circuit. Hence, the shunt circuit acts as a means of extracting mechanical energy from the base structure. In this study, a pulse-switching circuit is imposed as the semi-active shunt piezoelectric damping to reduce the structural vibration. The switch-law for the pulse-switching circuit is discussed in detail, and the detailed numerical calculations are given and discussed. It is found that the pulse-switching circuit is more stable than passive piezoelectric circuit (such as RL series circuit) with regard to structural stiffness variations.

Abstract:

An outstanding challenge in the nascent field of materials informatics is to incorporate materials knowledge in a robust Bayesian approach to guide the discovery of new materials. Utilizing inputs from known phase diagrams, features or material descriptors that are known to affect the ferroelectric response, and Landau–Devonshire theory, we demonstrate our approach for BaTiO3-based piezoelectrics with the desired target of a vertical morphotropic phase boundary. We predict, synthesize, and characterize a solid solution, (Ba0.5Ca0.5)TiO3-Ba(Ti0.7Zr0.3)O3, with piezoelectric properties that show better temperature reliability than other BaTiO3-based piezoelectrics in our initial training data.

Abstract:

According to the resonant characteristics of piezoelectric materials, in order to get the parameters of piezoelectric materials under DC bias voltage by calculate the impedance spectrum of piezoelectric materials, and the changes of the parameters of piezoelectric materials under DC bias were discussed. This paper measured the impedance spectrum of piezoelectric materials under different DC bias voltage with TH2828S Impedance Analyzer, and found that DC bias voltage made the material impedance spectrum drifted. Various parameters of materials were calculated by the resonance method, it was found that the parameters of piezoelectric materials under varied bias voltage were different, and the behaviours of each parameters under DC bias voltage were obtained.It was consider that the elastic constant and dielectric constant were changed due to the inverse piezoelectric effect of the piezoelectric materials which were under DC bias voltage,so that other parameters were changed.Then the resonant frequent formula of piezoelectric materials under DC bias voltage was deduced.

Abstract:

A piezoelectric microactuator for minimally invasive surgery procedures was developed using the piezoelectric tube actuator. The tube was fabricated by electrophoretic deposition of a doped PZT powders on the graphite rod substrate and co-sintering. The obtained tube shows maximum strain 0.045% in 31 mode and coercive field 1.5 kV/mm under static condition. Under dynamic condition, bending and longitudinal vibration modes can be identified from impedance spectrum and simulation. Theoretical analysis indicates that the displacement of the two modes depends on the geometry, material property, driving condition and damping conditions. The developed device uses bending mode to create rotation mechanical motion, and longitudinal mode to produce ultrasonic energy to soften and break up the target into fragments.
