Previous fundamental studies of the response of standardized piezoelectric polymer stress gauges have been largely based on impact experiments in which peak pressures as high as 46 GPa are achieved by ''ringing up'' to peak pressure in times of about 60 nsec. The shock-induced increase in temperature is minimized in this case. In order to study thermal effects and other possible influences in PVDF piezoelectric response, direct shock loading to high pressures have been carried out in high explosive plane-wave loading experiments. Measured piezoelectric charges to pressures up to 10 GPa are found to the the same in both ring-up and direct shock loading. At peak pressures of 32 GPa, the observed charge is reduced by about 20% in the direct shock experiments. 2 refs., 5 figs., 1 tab.
