This device is part of a system under developpment by Professor Eric Vogel and two Irish research teams that uses nanoscale-thick 2-D materials, lamined onto plastic substrates, to produce disposable semiconductors for quickly diagnosing bovine respiratory disease. (Photo: Rob Felt)
Micro-electromechanical systems, or MEMS, may not be on your mind, but there could be some in your pocket.
Your smartphone likely uses a dozen or so tiny — yet powerful — MEMS sensors to support its sophisticated functions. And that late-model car undoubtedly carries scores of devices based on MEMS and other sensing technologies.
Typically sized at the micron scale — millionths of a meter — MEMS devices use minuscule moving parts to perform a broad range of sensing tasks. Small as they are, they can detect sound, motion, position, force, pressure, chemicals, bacteria, and numerous other things worth knowing about. Note that these miniaturized sensors don’t always have moving parts, and a broader term — microsystems — is sometimes used rather than MEMS.
At Georgia Tech, more than 20 research teams focus on MEMS-related research and development. Supporting them is the Institute for Electronics and Nanotechnology (IEN), one of Georgia Tech’s nine Interdisciplinary Research Institutes. IEN’s extensive shared-user facilities, including advanced labs and cleanrooms, are used by as many as 200 Georgia Tech faculty, graduate students, and postdoctoral researchers who work on MEMS and other microsystems.

Professor Farrokh Ayazi has developed tiny gyroscopes that use MEMS technology to track firefighters or other first responders in covered areas where GPS signals are stymied -- in this case, the Krog Street Tunnel, an Atlanta landmark decorated by local artists. (Photo:Rob Felt)
