Description

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.

Learn more about NEMS from the resources available on this site, listed below.
