In this study, piezoelectric based compressive type accelerometer has been de-signed by using PZT-5A ceramics with bellewasher type spring. FEA analysis were carried out by using COMSOL. According to COMSOL simulation, reso-nance frequency is nearly 42500 Hz. Sensitivity of the designed sensors were measured and compared each other. Frequency spectrum was between 100Hz-10 kHz. The effects of piezodisk thickness, stiffness of the spring and seismic mass on the sensitivity of the designed sensor were investigated. Voltage output is in-creasing from 4.1 mV/g to 12.7 mV/g while seismic mass is raised from 3 gr to 10 gr. Linearity depending on the frequency of the designed accelerometer was dis-torted above 5.5 kHz like commercial accelerometer. In addition, real-time tests were performed using a calibrated accelerometer and a designed accelerometer on the internal combustion engine and drivetrain. Vibration profiles were carried out randomly. According to the results obtained here, it is observed that all the peaks were matched with a coefficient about 1.3.

“…Piezocomposites with piezoelectric ceramic (PZT-5A) as piezoelectric phase and epoxy resin as the polymer phase are used extensively in underwater and biomedical applications, due to its superior electromechanical coupling coefficient and broad bandwidth compared to piezoceramics [1]. There are various configurations of piezocomposites available, the most commonly used configuration is 1-3 type with active piezoelectric fibers (one-dimension) embedded in a polymer matrix (three-dimension) due to tailor made electromechanical properties, tunable acoustic impedance etc [2,3].…”

The effect of loading rate on ferroelectric and ferroelastic behavior of 1-3 piezocomposites is presented in this work. Experiments are conducted for various loading rates under different loading conditions such as electrical and electromechanical to measure the rate dependent response of 1-3 piezocomposite compared with bulk piezoceramics. A thermodynamic based rate dependent domain switching criteria has been proposed to predict the ferroelectric and ferroelastic behavior of homogenized 1-3 piezocomposites. In this model, volume fraction of six distinct uni-axial variants are used as internal variables to describe the microscopic state of the material. Plasticity based kinematic hardening parameter is introduced as a function of internal variables to describe the grain boundary effects. Homogenization of 1-3 piezocomposite material properties are obtained by finite element (FE) resonator models using commercially available FE tool Abaqus. To evaluate the possible modes of vibration of 1-3 piezocomposite four different configuration of FE resonators are modeled. The FE resonator model is validated with the impedance spectra obtained experimentally for length extensional and thickness extensional resonator models. The predicted effective properties using the resonance based technique are incorporated in the proposed rate dependent macromechanical model to study the behavior of 1-3 piezocomposites. The simulated results are compared with the experimental observations.

“…23 Various applications studies were also carried out to find out the performance when compared to the bulk PZT. [24][25][26] Electrical fatigue loading on 1-3 piezocomposites for high bipolar electric field shows the strong dependence on the degradation of material properties for various volume fraction of PZT fiber. The damages are more for decreasing fiber volume fraction which results in deterioration of material performance.…”

1-3 type piezocomposites are very attractive materials for transducers and biomedical application, due to its high electromechanical coupling effects. Reliability study on 1-3 piezocomposites subjected to cyclic loading condition in transducer application is one of the primary concern. Hence, this study focuses on 1-3 piezocomposites for various PZT5A1 fiber volume fraction subjected to electrical fatigue loading up-to 106 cycles and at various elevated temperature. Initially experiments are performed on 1-3 piezocomposites, in order to understand the degradation phenomena due to various range in amplitude of electric fields (unipolar & bipolar), frequency of applied electric field and for various ambient temperature. Performing experiments for high cycle fatigue and for different fiber volume fraction of PZT5A1 is a time consuming process. Hence, a simplified macroscopic uni-axial model based on physical mechanisms of domain switching and continuum damage mechanics has been developed to predict the non-linear fatigue behaviour of 1-3 piezocomposites for temperature dependent electrical fatigue loading conditions. In this model, damage effects namely domain pinning, frozen domains and micro cracks, are considered as a damage variable (ω). Remnant variables and material properties are considered as a function of internal damage variable and the growth of the damage is derived empirically based on the experimental observation to predict the macroscopic changes in the properties. The measured material properties and dielectric hysteresis (electric displacement vs. electric field) as well as butterfly curves (longitudinal strain vs. electric field) are compared with the simulated results. It is observed that variation in amplitude of bipolar electric field and temperature has a strong influence on the response of 1-3 piezocomposites.
