The most common piezoelectric polymer is PVDF, based on the monomer CH{sub 2}-CF{sub 2}. Electrical processing with the Bauer cyclic poling method can routinely produce individual samples with a range of remanent polarizations up to 9mC/cm{sup 2}. The behavior of PVDF has been studied over a wide range of pressures with the destructive, but precise, method of very-high-pressure shock loading. It appears that low inductance electrode lead designs prepared via a new poling procedure improve significantly the precision of the piezoelectric response of the PVDF gauges under shock loading. In particular piezoelectric current response of shock compressed PVDF film is of the order of one nanosecond. Studies to pressures of 30 GPa are available which show that the piezoelectric behavior is linearly dependent on volumetric strain to a close approximation as described in a companion paper. Anomalous response of PVDF observed are identified: solutions are given. The first record of detonation profile is presented. {copyright} {ital 1996 American Institute of Physics.}
