A microactuator is a microscopic servomechanism that supplies and transmits a measured amount of energy for the operation of another mechanism or system. As a general actuator, following standards have to be met:
- Large travel
- High precision
- Fast switching
- Low power consumption
- Power free force sustainability
For microactuator, there are two in addition
- Microstructurability
- Integrability
Principle of microactuators
The basic principle can be described as the expression for mechanical work
[math]\displaystyle{ W=\overrightarrow{F}\cdot \Delta \overrightarrow{r} }[/math]
since an actuator is to manipulate positions and therefore force is needed. For different kind of microactuators, different physical principles are applied.
Classes of microactuators
- Electrostatic
- Electromagnetic
- Piezoelectric
- Fluid
- Thermal
