Abstract:

Micro/Nano
-
Electro
-
Mechanical Systems (MEMS/NEMS) are miniature devices which integrate mechanical
elements, sensors, actuators, and electronics with multi
-
functional characteristics. The manufacture
of MEMS
has been facilitated by the integrated circuit (IC) and micromachining processes, which were originally
developed for the electronics industry. This lecture begins with definition and overview of nanotechnology and
MEMS. The common manufacturing t
echniques employed in the fabrication of MEMS are introduced. The
application of engineering principles in the design of MEMS is highlighted. A number of applications where
these principles are utilized including transducers (pressure, acceleration), mecha
nical devices, mechanisms, and
digital displays are presented. Recent advances in research leading to novel advances in enhancing the
performance and reliability of MEMS are discussed.

Guruswami Ravichandran is the John E. Goode, Jr. Profes
sor of Aeronautics and Mechanical Engineering and
the Director of Graduate Aerospace Laboratories (GALCIT) at the California Institute of Technology. He
received his B.E. (Honors) in Mechanical Engineering from the University of Madras, Sc.M. in Engineerin
g and
Applied Mathematics, and Ph.D. in Solid Mechanics and Structures from Brown University. He is a Fellow of
American Society of Mechanical Engineers (ASME) and Society for Experimental Mechanics (SEM). His
