Abstract :
An energy-autonomous and MRI-compatible CMOS implantable sensor is presented that operates by harvesting the energy of the light which penetrates into the tissue. On-chip P+/N-well diodes are used as on-chip photovoltaic cells and in-vivo physiological data is transmitted neuromorphically to the skin surface.
