Micro actuators are small devices that convert energy into motion at a microscopic scale. They are commonly used in various applications, including robotics, medical devices, and consumer electronics. These actuators can manipulate tiny components with precision, making them essential for tasks that require fine control. There are several types of micro actuators, including electrostatic, thermal, and piezoelectric actuators. Each type operates based on different principles, such as electrical charge or temperature changes, to create movement. Their compact size and efficiency make them valuable in advancing technology in fields like nanotechnology and MEMS (Micro-Electro-Mechanical Systems).
