Abstract
The advantages of using piezoelectric polymer (plastic) materials as the sensitive element in miniature ultrasonic hydrophone probes are described, and proposed designs are critically reviewed. A novel needle type of probe design is described in detail, together with calibration results of the sensitivity and directivity of 0.6 mm and 1 mm diameter probes. The former typically have an end of cable sensitivity of −271 dBV μPa
−1 ± 2 dB between 1 and 10 MHz, the latter of −264 dBV μPa
−1 ± 1.5 dB. The linearity, temporal stability and thermal stability of those probes are also discussed. They are shown to be small and reliable instruments for obtaining good spatial and temporal resolution in ultrasonic field measurements.
