Piezoelectric composites with high sensitivity and high capacitance for use at high pressures


A type of piezoelectric composite has been developed for oceanographic applications. The composites have a large figure of merit (d/sub h/*g/sub h/ or d/sub h/*g/sub h//tan delta , where d/sub h/ is the hydrostatic piezoelectric voltage coefficient), a large dielectric constant (K) and low dielectric loss, and great mechanical strength. A shallow cavity… (More)
