Magnetoelectric film on top of rice

From Rice University neuroengineers: “The neural stimulator draws its power from magnetic energy and is about the size of a grain of rice. It is the first magnetically powered neural stimulator that produces the same kind of high-frequency signals as clinically approved, battery-powered implants that are used to treat epilepsy, Parkinson’s disease, chronic pain and other conditions.”  MORE
