Micro-Electro-Mechanical Systems, or MEMS, are tiny devices that combine mechanical and electrical components at a microscopic scale. They are often made using semiconductor manufacturing techniques, allowing for the creation of sensors, actuators, and other components that can perform various functions. Common applications of MEMS include accelerometers in smartphones, pressure sensors in automotive systems, and micro-mirrors in projectors. MEMS technology enables the development of highly efficient and compact devices that can sense and respond to their environment. These systems can be found in everyday products, enhancing functionality and performance. As technology advances, MEMS are expected to play an increasingly important role in fields like healthcare, automotive, and consumer electronics.
