* [[Piezoelectricity|Piezoelectric]] materials can produce a voltage when mechanical stress is applied. This effect also applies in a reverse manner, a voltage applied across the material will produce mechanical stress within sample. Therefore structures made from these materials can be designed to bend, expand, or contract when a voltage is applied. |
