piezoelectric

• Relatif à l'électricité produite ou à la charge électrique qui s'accumule dans certains matériaux solides (tels que les cristaux, certaines céramiques et des substances biologiques) en réponse à une contrainte mécanique appliquée.

Relating to the electric charge that accumulates in certain solid materials (such as crystals, certain ceramics, and biological matter) in response to applied mechanical stress.
