Casimir and van der Waals interactions in RF MEMS Switching Devices
Microelectromechanical systems (MEMS) struggle with surface interactions, called van der Walls forces, which can make nanomaterials sticky to the point of permanent adhesion, a phenomenon known as "stiction". To defeat stiction, many MEMS devices are coated with Teflon or similar low-friction substances or are studded with tiny springs that keep the surfaces apart. Materials that did not require such fixes could make nanotechnology more reliable. Such materials could skirt another problem posed by adhesion: Because surface stickiness at the Nanoscale is much greater than it is for larger objects, MEMS designers resort to making their devices relatively stiff. That reduces adhesion (stiff structures do not readily bend against each other), but it reduces flexibility and increases power demands.

Casimir and van der Waals interactions in RF MEMS Switching Devices
The Casimir force, which rapidly increases as the surface separation decreases, is the dominant interaction mechanism between neutral objects at sub-micron distances. In light of the miniaturization process that is moving modern technology towards smaller electromechanical devices, it is reasonable to ask what role the zero-point energy might play in the future development of micro-and nano-electromechanical systems (MEMS and NEMS).
