MEMS Actuators are tiny devices that convert electrical signals into mechanical movement. They are part of the Micro-Electro-Mechanical Systems (MEMS) technology, which integrates mechanical and electrical components at a microscopic scale. These actuators are commonly used in various applications, including sensors, optical devices, and medical instruments, due to their small size and efficiency. The operation of MEMS actuators often involves the use of materials that can change shape or position when an electric current is applied. This allows for precise control in applications such as microvalves, micro-mirrors, and inkjet printer heads. Their compact design enables innovative solutions in modern technology.
