MEMS Switch Extends Life of Cellphones

A new type of microelectromechanical system (MEMS) was developed that uses electrostatic levitation to provide a more robust system. All cellphones use MEMS switches for wireless communication, but traditionally there are just two electrodes. The switches open and close numerous times during just one hour,...
