A ferroelectric sensor operated in the temperature auto-stabilized mode was developed for the measurement of the particle motion in hydroacoustic fields. The sensor is a capacitor-like element constructed from antimony sulfur iodide (SbSI) single crystals and SbSI-polymer composites. The device is operated slightly above the Curie point of SbSI which is approximately 20 C. Using a Schering bridge, the element is heated by driving it through the hystersis cycle. The ...
