Title: (3,1) Drive PVDF acoustic displacement sensor

Abstract

A (3,1) drive piezofilm vibration sensor is introduced. Operated above the lumped element resonance frequency of 600 Hz, the sensor delivers a voltage signal proportional to displacement over the frequency range of 2 kHz to 8 kHz. It is anticipated that the sensor response is flat above 8 kHz, but calibration has not been performed at higher frequencies. The sensor is very sensitive, detecting acoustic displacements as small as 10{sup {minus}5} nm. Because of its simple design the sensor is robust and easy to assemble. {copyright} {ital 1996 American Institute of Physics.}
