PVDF (polyvinylidene difluoride) piezoelectric film has many properties that make it attractive for underwater acoustic applications. In order to utilise these it has been necessary to understand some of the basic mechanisms affecting the performance of this material as an underwater sensor. In order to do this, hydrophones have been constructed using thick film (28 μm) PVDF elements which have been mounted on various substrates and encapsulated in polyure-thane. The effect of the substrate shape and material on the sensitivity and directionality of the hydrophones has been measured at frequencies from 40 kHz to 100 kHz and their useability as an underwater sensor discussed.
