Nano Electro-Mechanical Systems (NEMS) are tiny
machines built at the nanometer scale. Current
NEMS applications are simple machines, such as
the tiny cantilever shown at the right. An electrical circuit measures the deflection
of the lever. A larger version of this device,
with dimensions at the micrometer or millimeter
scale, is commonly used as an airbag sensor in
automobiles. A sudden stop causes a strong
deflection of the lever, which signals that
the airbags should be deployed. At the nano
scale, such a lever is sensitive enough to
measure the weight of individual atoms or
molecules resting upon it.

Nanotribology, Nanomechanics and Materials Characterization Studies
08 Jun 2009 | | Contributor(s):: Bharat Bhushan
Fundamental nanotribological studies provide insight to molecular origins of interfacial phenomena including adhesion, friction, wear and lubrication. Friction and wear of lightly loaded micro/nano components are highly dependent on the surface interactions (few atomic layers). Nanotribological...

Experiences with nonintrusive polynomial Chaos and stochastic collocation methods for uncertainty analysis and design
out of 5 stars
13 Mar 2009 | | Contributor(s):: Michael S. Eldred
Non—intrusive polynomial chaos expansion (PCE) and stochastic collocation (SC) methods are attractive techniques for uncertainty quantification due to their abilities to produce functional representations of stochastic variability and to achieve exponential convergence rates in statistics of...

High-Aspect-Ratio Micromachining of Titanium: Enabling New Functionality and Opportunity in Micromechanical Systems Through Greater Materials Selection
18 Jun 2008 | | Contributor(s):: Masa Rao
Traditionally, materials selection has been limited in high-aspect-ratio micromechanical applications, due primarily to the predominance of microfabrication processes and infrastructure dedicated to silicon. While silicon has proven to be an excellent material for many of these applications, no...
