Beschreibung
Zusammenfassung:	The present invention provides a process for the preparation of semi-conducting polymer film containing beta crystalline phase of polyvinylidene fluoride with application in piezoelectric devices viz. electro-mechanical sensors, tactile sensors for robotics, touch sensitive switches and the like, and which can be easily made at low temperatures and at low electric fields and having low resistivity/semi-conducting range.
