Applications of Ferroelectric CVD Materials

The major piezoelectric applications are sensors (pickups, keyboards, microphones, etc.), electromechanical transducers (actuators, vibrators, etc ), signal devices, and surface acoustic wave devices (resonators, traps, filters, etc ). Typical materials are ZnO, AIN, PbTiOg, LiTaOg, and Pb(Zr.Ti)03 (PZT). 

The maj or pyroelectric applications are those related to infrared sensing such as cooking controls, fire or heat alarms, door openers, etc. Typical materials are LiTa03, PbTi03, andPb(Zr.Ti)03.
