Nanoelectromechanical systems

Nanoelectromechanical systems will be very tiny machines, with dimensions thousands of times thinner than the human hair, that could be used as motors or sensors. The technology is very new and still in the laboratory stage, but may replace microelectromechanical systems.

Compared to human scale, things work very differently at nano dimensions. For example, attractive forces between materials of the same type may push together moving parts and block a motor.

This short article about technology can be made longer. You can help Wikipedia by adding to it.

A die shot (after metallization/ IC interconnect removal) of the digital die of the SiTime SiT8008, a programmable oscillator reaching quartz precision with high reliability and low g-sensitivity. The nanoscale transistors and nanoscale mechanical components (on a separate die) are integrated on the same chip package.
