AbstractPiezoelectric lead–zirconate–titanate (PZT) elements were studied by directly bombarding hypervelocity silver and iron particles in the velocity range of 2–63km/s. This report focuses on the concept of “immediately after collision”. This concept was realized in the leading part of a pulsed signal that exhibited no effects due to reflection. The signal form was discussed from the viewpoint that information on impact was recorded by the waveform. The results indicated that the output amplitude was independent of the thickness of a PZT element, and that the waveform was explicitly related to the velocity at collision. Further, it appeared as an oscillating form at velocities less than 6km/s. As the velocity increased, it gradually changed to a solitary pulse. The rise time of the single solitary waveform was linearly related to velocities above 6km/s. The potential of a single PZT element is discussed as a real-time detector for hypervelocity microparticles.
