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.
