Introduction of Basic Information Regarding Piezoelectric Actuator


There can be many different applications of piezoelectric materials in various mechatronic systems. Also, as an actuator too piezoelectric material can have plenty of scope if the designers can think of out of box solutions.

These multilayer piezo actuators can be classified in many different types:

  • Piezoelectric actuators

Generally, these actuators are used in internal combustion engines for controlling fuel injection system.

  • Electrochemical actuators

It has use in airbag expansion systems.

  • Artificial muscles

You can find in humanoid robots this is used for manipulation and mobility features.

  • Shape memory actuators
