ABSTRACT
Polymer-ferroelectric ceramic composites, after poling, control as much as they can for both theoretical and practical reasons. On the one hand, they are becoming increasingly more important as materials for the study of charge transport and its storage phenomena in multicomponent systems; what is more, there has been a rapid development in their applications in a wide range of devices. The most well-known applications of such composites include electromechanical transducers, above all microphones and hydrophones, as well as pyroelectric detectors in infrared sensors and microcalorimeters.
