US Patent 10088358 Implantable systems and methods for UV dose monitoring

An ultra violet (UV) light dose monitoring system may include an implantable microchip for injection below the surface of a person's skin. The microchip may include a solar cell, a data telemetry transmitter, and a first sensor cell that absorbs UV light that passes through the skin. The system may also include a remote reader. The remote reader may include a data telemetry receiver that receives the data from the microchip and a processor for controlling operation of the remote reader. The data telemetry transmitter may transmit data indicative of a UV light intensity for the UV light absorbed by the first sensor cell to the data telemetry receiver, and the processor may calculate a UV dose based on the data.
