MEMS hinge device. Coloured scanning electron micrograph of a MEMS (microelectromechanical systems) hinge device. MEMS devices are constructed on a microscopic scale using technologies such as wet and dry etching and thin film deposition. Applications include sensors and optical displays. Materials used to construct MEMS devices include silicon and polymers such as plastics. This device is used to erect structures. Magnification: x790, when printed 10 centimetres wide.
