Micro-Electro-Mechanical Systems, or MEMS, is a new technology that marries mechanical and electronic systems at microscopic levels, hence the name. MEMS are used in accelerometers, digital micromirrors, and more.  Accelerometers are electronic devices that measure acceleration, popular applications of which include automobile crash sensors and wireless gaming controls.

This video from the MEMS Industry Group provides an introduction to MEMS. Shown were examples of MEMS applications in manufacturing, automotive, life sciences, and consumer electronics.
