Neural dust is a term used to refer to millimeter-sized devices operated as wirelessly powered nerve sensors. The sensors may be used to study, monitor, or control the nerves and muscles and to remotely monitor neural activity. In practice, a medical treatment could introduce thousands of neural dust devices into human brains. The term is derived from smart dust, as the sensors used as neural dust may also be defined by this concept.
