In most crystals (such as metals), the unit cell (the basic repeating unit) is symmetrical; in piezoelectric crystals, it isn’t. Crystals which acquire a charge when compresse twisted or distorted are said to be piezoelectric. This provides a convenient transducer effect between . Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress.
This post discusses how you can correctly model the crystal orientation and poling direction of a piezoelectric material in your COMSOL . Piezoelectric Motors — One advantage of using piezoelectric materials is that their characteristics are precise and predictable. Piezoelectric materials all possess different properties. Choose the piezoelectric material appropriate for your application.
