In the case of harnessing vibrations, Chandrakasan and his colleagues use piezoelectric materials, which produce an electric current when subjected to mechanicalpressure.
至于在约束振动上,切卓卡山和他的同事们使用了压电体,在经受力的作用下,它可以产生电流。

The researchers applied varying degrees of mechanicalpressure to hundreds of extracted teeth, and studied what occurred on the surface and deep inside them.
