Piezoelectricity in polymers [PDF]

The Journal of the Acoustical Society of America, 1980
Certain polymer materials, when electrically charged, exhibit a strong piezoelectric effect. Most prominent among these is polyvinylidene fluoride (PVDF) whose piezoelectric behavior was discovered only about a decade ago. In the present paper, the various change storage effects in PVDF and other polymers will be described, and the relation between the
