A PVDF Trigger and Tilt Detector for Projectile Impact Experiments

Abstract

A sensor is described which is used as a trigger source for shock wave and projectile impact experiments, and also measures projectile tilt. The piezoelectric device uses plyvinylidene difluoride (PVDF) as the sensor. Two independent signals are produced: one a piezoelectric signal, the other a contact-closure signal. This duality significantly improves the reliability of the trigger. Full experimental details, theoretical analysis, and results are provided. To date this trigger has been used successfully by the authors many times without a single failure.
