Indigenous piezoelectric Polyvinylidene Fluoride (PVDF) films have been developed successfully. The know-how for the processing and characterization of PVDF films to achieve higher piezoelectric properties has been attained. These films have been used to develop indigenous accelerometer devices for vibration applications
