A multi-piezoelectric structure: the stacked transducer
IEEE 1991 Ultrasonics Symposium, 2002A new piezoelectric structure made of several ceramic plates stacked together is proposed. With such an arrangement a gain in sensitivity can be obtained via constructive addition of the different ceramic signals appropriately delayed. Conversely, a reduction of the pulse duration can be achieved with destructive interference.

Development of a piezoelectric proton exchange membrane fuel cell stack (PZT-Stack)
Journal of Power Sources, 2013Abstract Previous studies report that bi-cell piezoelectric proton exchange membrane fuel cells with a nozzle and a diffuser have been successfully developed, and this pseudo-bipolar design is expected to benefit the future development of the piezoelectric stack (PZT-Stack). In this study, an innovative PZT-Stack design composed of three L-PZT-D-type

Review of Scientific Instruments, 2016
For the piezo-driven microgripper, one issue is to enlarge the grasping stroke and realize parallel grasping movement in the compact design. Piezoelectric stack actuator (PSA) and piezoelectric cantilever actuator (PCA) are two kinds of typical piezoelectric actuators. In this study, a novel microgripper hybrid driven by a PSA and two PCAs is proposed,

Modeling for Piezoelectric Stacks in Series and Parallel
2013 Third International Conference on Intelligent System Design and Engineering Applications, 2013Piezoelectric energy harvesting is a new type technology of green energy. To increase energy harvesting efficiency from below frequencies, which exist mostly in ambient, the piezoelectric stack assembled electrically in series and parallel is used as the energy harvester.

Sling-shot buckling in stacked piezoelectric structures
2014A stacked structure consisting of two beam-plates, each being a different piezoelectric material, subject to a uniformly increasing electric field is analyzed. One beam-plate is perfectly adhered over the central portion of the other. We consider the limiting boundary conditions for the bottom layer, the baseplate: clamped-fixed and hinged-fixed ...
