MEMS combines angular rate, acceleration sensors

What is a sensor?
A device that receives and responds to a stimulus or signal. Sensors measure real-world conditions, such as heat or light, and then convert this condition into an analogue or digital representation.

What does MEMS stand for?
MEMS stands for microelectromechanical systems. They are tiny mechanical devices that are built onto semiconductor chips and are measured in micrometers. They are used to make pressure, temperature, chemical and vibration sensors, light reflectors and switches as well as accelerometers for airbags, vehicle control, pacemakers and games.
