The research work presented here shows the progress realized in the studies of the ferroelectric and piezoelectric properties of Polyvinylidene Flouride (PVDF). An attempt has been made to understand the fundamental phenomena of the mechanism responsible for the functioning of the shock loaded ferroelectric PVDF. Fundamental questions have not yet found a sufficient response. The main parameter which must be taken into account in the standardization process, is the polarization which is fixed at a value of 9.15 +- 0.15 ..mu..C/cm/sup 2/. There are different PVDF, but it seems clear that there is only one piezoelectric PVDF which can be used for shock gauge transducers.
