    Piezoelectric lead-zirconate-titanate was studied by bombarding with silver particles in the mass range from 2 to 100 pg, and the velocity range from 2 to 8 km/s. Output signals were uniquely identified on impact. It was found that incident energies above 100 nJ were measured unambiguously by a single lead-zirconate-titanate element. The detector characteristics were studied with respect to incident particle energy, angular dependence and size effects. Even though we have still unknown processes inherent in this detection method, the piezoelectric element has a potential as a real-time detector, if it is well calibrated.
