PIEZOELECTRIC EFFECT

Piezoelectric Effect is the ability of certain materials to generate an electric charge in response to applied mechanical stress.

REVERSE PIEZOELECTRIC EFFECT

The Reverse Piezoelectric Effect is the opposite. It's when you apply an electrical charge to produce a mechanical strain.

PRINCIPLE

Inside a quartz clock or watch, the battery sends electricity to the quartz crystal through an electronic circuit. The quartz crystal oscillates (vibrates back and forth) at a precise frequency: exactly 32768 times each second. The circuit counts the number of vibrations and uses them to generate regular electric pulses, one per second. These pulses can either power an LCD display (showing the time numerically) or they can drive a small electric motor (a tiny stepping motor, in fact), turning gear wheels that spin the clock's second, minute, and hour hands.
