High-fidelity acoustic-emission sensor/preamplifier subsystems: modeling and experiments

A computer model is used to evaluate the suitability of five piezoelectric materials for use in broadband (10 kHz-2 MHz) acoustic-emission (AE) 'point' sensors. The computer model accounts for the effects of the electrical loading of the piezoelectric material by the input impedance of the...
