Abstract

In recent years, major developments in RF based power transmission systems have made a great impact in the progress of wirelessly powered implantable biomedical devices. In this paper, we present a multichannel and multi-wavelength optogenetic stimulator, suitable for chronic and acute implantation in freely moving rodents. Optogenetic stimulators provide a pathway for complex spatiotemporal control of photosensitized neurons in the brain. The design consists of an 8×8 micro light emitting diode array of equally spaced amber and blue LED pairs at alternate positions. The closely packed illumination structure facilitates light delivery at a high spatial (0.5mm) and temporal (0.1 ms) resolution. Low Frequency RFID (Radio Frequency Identification) technique was used for both power delivery and communication with the onboard low power microcontroller via custom built Reader circuitry.
