Microactuator
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 W = F → ⋅ Δ r → {\displaystyle W={\overrightarrow {F}}\cdot \Delta {\overrightarrow {r}}} since an actuator is to manipulate positions and therefore force is needed.
