MICRODEVICE FOR SENSING A FORCE

摘要

A microsensor or micromechanical device based upon the piezoelectric properties of thin film lead zirconate titanate (PZT) with a thickness of between 0.1 and 5 microns. The thin film PZT is sandwiched between first and second electrodes which are provided with electrical connection means for electrically connecting the electrodes to a voltage sensor or voltage source. The invention also relates to a method for making such microsensor or micromechanical device.
