Flexible piezoelectric composite transducers

摘要

A flexible, low-density piezoelectric transducer utilizing a PZT-polymer composite that is formed with the two phases three-dimensionally interpenetrant. The ceramic PZT microstructure, which is produced by a replication process that in one embodiment reproduces the structure of a coral species, is filled with silicone rubber and thereafter its transverse connectivity is broken by a light shearing deformation to give it flexibility.
