Piezoelectric Materials

High Sensitivity "Soft" Materials	High sensitivity or "soft" ceramics feature high sensitivity and permittivity, but under high drive conditions are susceptible to self heating beyond their operating temperature range . These materials are used in various pick-ups and sensors, low-power motor-type transducers, receivers, and low power generators.
DOD STD - 1376A (SH) Type II PZT-5A/PC5	This material is used as the receiver or generator element in hydrophones, accelerometers, and vibration pickups. These materials have high sensitivity, permittivity, time stability and can withstand relatively high temperatures in application.
DOD STD - 1376A (SH) Type V PZT-5J	This material is used in fuses, hydrophones, and other applications that require a combination of high energy and high voltage output. PZT-5J has high permittivity and a high piezoelectric voltage constant.
DOD STD - 1376A (SH) Type VI PZT-5H	This material is used in sensitive receivers and applications requiring fine movement control. It has been used in a wide range of applications from hydrophones to ink jet printers. PZT-5H provides extremely high permittivity, coupling, and piezoelectric constant.
