PIEZOELECTRIC POLYMER TRANSDUCER FOR IMPACT PRESSURE MEASUREMENT
Described are development efforts relating to the design, construction, and calibration of a piezoelectric polymer transducer for the recording of pressure transients developed over the interface between two bodies as a result of impact. A bilaminate design was selected which uses electrically poled sheets of 25 micrometer poly(vinylidene fluoride) as the active material. The intended primary response of the transducer is to compression in the thickness direction, which is produced by either hydrostatic or normal pressure; the transducer was also found to respond to extension in the membrane direction.
