Piezoceramic material—non-conductive piezoelectric ceramic or crystal—is placed between the two metal plates. For piezoelectricity to be generated, it needs that material to be compressed or ...

For example, ideas to underlay roads with piezoelectric materials and produce large amounts of power from cars driving over the top, or electricity-producing shoes draw publicity now and then.

Since the crystal is piezoelectric, he wondered if using a high DC voltage to bend the crystal to move the frequency to create a variable crystal oscillator (sometimes called a VXO).

A PROPERTY of many semiconductors which so far has not been exploited is that of piezoelectricity. So 63 years ago started a story in Electronics Weekly’s edition of May 3rd 1961 Many of the crystal ...
