piezoelectric devices
Various piezoelectric devices, which form an inseparable part in the progress of modern communication devices, television, radars, and several kinds of defence technology are being produced by the thousands in developed countries all over the world.
      
Analysis of the insulating, piezoelectric, and mechanical properties of the samples demonstrates that there is a group of solid solutions that are promising materials for high-temperature piezoelectric devices operating in the medium-frequency band.
      
Simulating the response of piezoelectric devices requires solving coupled electrical and mechanical partial differential equations.
      
A shape-memory-alloy actuator which memorizes the linear shape was used to realize a driving amount larger than those of electrostatic actuators and piezoelectric devices.
      
The films thus produced show a step forward in developing piezoelectric devices using more economic routes.
      
Piezoelectric devices for the detection of NH3, H2S, SO2 and CO in the parts per milliard range have been developed.
