Piezoelectric materials generate voltage in response to stress, vibration, and other external sources. Applications include microphones and strain sensorsThe two prime piezoelectric materials have some drawbacks. Applications near motors and engines, in space environments, and on heat transfer piping require piezoelectric materials to perform at above 100°C in hot ambient environments. Toray innovated its piezoelectric polymer by drawing on its polymer molecular design and higher-order structural control technology.
