Piezoelectricity

Posted on 1/25/2016 10:11:28 AM

The piezoelectricity is the characteristic by which some crystals, quartz, topaz, and others, like crystal ceramic (piezo ceramic), can be electrically loaded through a mechanical deformation, or alternatively can change shape when submitted to an electrical field action.

Difference:
Transducers convert a power form into another, for instance: pressure, temperature, etc. into an electrical signal.
Piezo Actuators convert electrical power into mechanical power (motors) or, alternatively,mechanical power into electrical power (generators).
On Piezo Injectors the actuators are used as ‘motors’ and modify their shape under the action of an electrical fields.
