In an embodiment, the present disclosure pertains to an organ-specific
wireless optogenetic device. In some embodiments, the device includes an
electronic circuit, such that the
electronic circuit is configured to harvest and convert
radio frequency (RF) energy into
optical energy and a tether having a μLED, where the μLED illuminates targeted regions in the organ. In an additional embodiment, the present disclosure pertains to a method of treating
obesity. In general, the method includes implanting an organ-specific
wireless optogenetic device into a subject, activating an RF-power
system to produce RF energy, harvesting, by the organ-specific
wireless optogenetic device, the RF energy, converting, by the organ-specific wireless optogenetic device, the RF energy into
optical energy, illuminating, by the μLED, targeted regions in the
stomach of the subject, and stimulating nerve endings to thereby suppress
appetite in the subject.
