One of the first commercial applications of MEMS (micro-electro mechanical systems) technology was for sensors used in automotive safety systems. MEMS technology has spread to other applications including microphones for mobile phones and acceleration sensors and gyroscopes for portable gaming devices and tablets. Now MEMS technology is successfully used in timing devices such as resonators, oscillators and clock generators used in a wide variety of electronics systems. MEMS timing is now bringing new benefits to systems that use touchscreen technology. Touchscreens, used for human-machine interface, have become widely used in many devices especially in portable consumer devices that use capacitive touch sensing as the primary method of user interface.
