APC International Releases eBook: First Steps Towards Piezoaction

Piezo stack actuators are used as linear electromechanical drives or motors. They act mainly like an expanding element ("pusher") generating a compressive force. The complete motion cycle is nearly proportional to the voltage signal input from DC up to high frequencies. From an electrical point of view, piezo-actuators behave like electrical capacitors. The induced motion can also be described as the consequence of the variation of the electrical charge content of the piezo actuator. Piezo actuators are based on special smart materials: The electo-active piezoeceramic material is known as PZT...To read more, download a free copy of APC's eBook: First Steps Towards Piezoaction.
