A device for brain stimulation using radio frequency harvesting is
disclosed. The device includes a circuit implantable under a scalp of a
patient, the circuit comprising a radio frequency harvesting power
circuit and a stimulation circuit, and a plurality of electrodes coupled
to the circuit, the plurality of electrodes providing brain stimulation
to targeted areas of the brain. The electrodes may provide stimulation to
targeted areas of the brain including deep brain stimulation for the
treatment of Parkinson's disease and cortical stimulation for the
