MEMS neural interface chip. Coloured scanning electron micrograph of a concave electrode array from a MEMS (microelectromechanical systems) neural interface 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 designed to connect to the brain to allow direct electrical communication with the brain's neurons. Magnification: x45, when printed 10 centimetres wide.
