MEMS (Microelectromechanical Systems) is a field of engineering and technology that involves the design and fabrication of extremely small mechanical and electromechanical devices that are integrated with electronic components on a silicon substrate. These devices typically range in size from a few micrometers to a few millimeters, and can include sensors, actuators, switches, and other types of devices. MEMS devices have a wide range of applications, including in consumer electronics, automotive systems, medical devices, and aerospace technology. They are known for their small size, low power consumption, and high reliability, making them ideal for use in devices where size and performance are critical. Research in the field of MEMS focuses on improving the performance, functionality, and reliability of MEMS devices, as well as exploring new applications and technologies that can benefit from MEMS technology. This research often involves developing new fabrication techniques, materials, and design methods to create more advanced and integrated MEMS devices.
