Categories Related to Electrostatic Actuators
An electrostatic actuator is a device that moves object by converting energy generated by electrostatic forces into motive force.
Actuators are mainly used in the field of optics, including components such as variable focus lenses, shutters, and displays.
Characteristics include light weight, flexibility, thinness, and transparency.
Examples of research include artificial muscles, hands, and legs for robots, with ongoing development to enable movements similar to actual human parts.
These actuators operate based on parallel plate capacitors. The electrostatic force generated is proportional to the plate area and inversely proportional to the square of the distance between the plates. Their small size leads to a lower absolute driving force, which is often compensated by increasing the area of the actuators or using thin films.
In addition to electrostatic types, other actuators include:
