MEMS (micro electro mechanical systems) are miniaturized 3D devices consisting of microelectronic components (integrated circuits) and micromechanical, optical, chemical, biochemical, or micro-optical components. MEMS technology is a rapidly emerging field with a high-growth rate. Motion sensors, micro mirrors, microphones, gyroscopes, and accelerometers are just a few types of the MEMS devices that are found in consumer applications such as cell phones, television sets, digital cameras, gaming consoles and laptops.
