“…Lead zirconate titanate materials (Pb(Zr,Ti)O 3 ; PZT) having perovskite-type ABO 3 are well known for their good piezoelectric properties and are ideal candidates for use as position ultrasonic transducers, hydrophones, speakers, fish finders, sensors, actuators, electrical resonators, and wave filters [1][2][3][4][5]. It has been reported that fabricating PZT through an improved synthesis process and appropriate substitutions at A and/or B sites can modified the microstructures and properties of PZT [6][7][8][9][10][11].…”

“…This has limited its application to micro robots and other small load applications. Numerous strain amplifying mechanisms have been presented in the literature, for example [12], [14], but such PZT amplification mechanisms achieve less than 2% strain. Recently, an effective mechanism for amplifying strain has been found that achieves an order of magnitude higher amplification in a compact structure [13].…”

This paper presents the dynamic analysis of an artificial muscle actuator designed for high-bandwidth, powerlaw strain amplification. The actuator is based on a nested cellular architecture of PZT stack actuators. Most smart material actuators have seen limited use in mobile robotic applications because of their small strain, low stress capacity, low bandwidth, and stringent input requirements. The proposed actuator design overcomes these limitations and can serve as a high-bandwidth multifunctional artificial muscle. The dynamic characteristics of the actuator design are derived analytically and validated experimentally. A test system mimicking flapping flight is then used to illustrate the actuator dynamics.

“…Piezoelectric materials have been widely studied and utilized in the applications of smart structures [4,5]. Piezoelectric ceramics such as lead titanate (PT) and lead zirconate titanate (PZT) are commonly used because they have high electromechanical coupling coefficient k t and high piezoelectric d coefficients.…”

To improve the compatibility between the sensor material and civil engineering structural material, a new functional cement-based composite for smart structure applications has been studied. Piezoelectric lead zirconate titanate (PZT) fibres, fabricated using a slurry method, are embedded in a cement matrix to form PZT/cement 1-3 composites. By incorporating PZT fibres into the cement matrix, composites with low PZT volume fractions ranging from 0.05 to 0.22 have been fabricated. The 1-3 composites have good piezoelectric properties that agree quite well with theoretical modeling. The thickness electromechanical coupling coefficient of the composites could reach ∼0.5 even for low volume fraction of PZT. These composites have potential to be used as sensors in civil structure health monitoring systems.
