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
