Abstract: Shock-induced depolarization of ferroelectric generators (FEGs) was used to charge a small capacitor bank. Lateral and longitudinal orientations of the FEG were investigated. The shock was provided by a sheet of explosives sandwiched with steel plates. Two different mounting concepts were explored. The first mounted the FEG to the edge of the sandwich using a machined coupler, and the second mounted the FEG to the face of the sandwich. The peak charge transferred from the PZT 95/5 material was measured to be 26.8 μC/cm2.
