Self-Regulated Wireless Power and Simultaneous 5MB/S Reverse Data over One Pair of Coils

A system of coupled resonators delivers wireless power of up to 93 mW to a biomedical implant, self-regulating the received voltage over coil separation and large changes in load current. A new modulation method, L-RSK, enables concurrent data transfer at up to 5 Mb/s in the reverse link.
