Abstract: Exemplary embodiments of this disclosure include apparatus, systems and methods utilizing a passive, power-efficient backscattering communication system that enables transmitting data wirelessly between implantable magnetoelectric (ME) devices and an external base station. Certain embodiments encode the transmitted data through modulating the resonance frequency of a ME film by digitally tuning its electric loading conditions.

Abstract: The disclosure describes new apparatus, systems and methods utilizing magnetoelectric neural stimulators with tunable amplitude and waveform. Specific embodiments of the present disclosure include a magnetoelectric film, a magnetic field generator and an electrical circuit coupled to the magnetoelectric film, in particular embodiments, the electrical circuit comprises components configured modify an electrical output signal produced by the magnetoelectric film. In certain embodiments, the electrical circuit is configured to modify the electric signal to charge a charge storage element, to transmit data to an implantable wireless neural stimulator, and to provide a stimulation output to electrodes.
