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.
