Microactuators are tiny devices that convert electrical energy into mechanical motion. They are often used in applications requiring precise control, such as in robotics, medical devices, and optical systems. These actuators can manipulate small components, enabling functions like movement, positioning, and switching. Typically made from materials like silicon or polymers, microactuators can be found in various forms, including piezoelectric and electrostatic types. Their small size allows for integration into compact systems, making them essential in modern technology. As advancements continue, microactuators are becoming increasingly important in fields like nanotechnology and microelectronics.
