Beschreibung
Zusammenfassung:	Implantable piezoelectric polymer film microphone apparatus and methods are described for use as an integral component of a hearing augmentation device system. The piezoelectric polymer film can be polyvinylidene fluoride ("PVDF"). Generally, a piezoelectric polymer film serves as the sensor that is well matched to tissue and which directly converts to an electrical signal by the piezoelectric effect vibration signals which are received through the tissue in which the piezoelectric polymer film microphone is implanted.
