Zusammenfassung:	Systems and methods for passive radio enabled power gating for a body mountable device are disclosed. In one embodiment, a system for power gating includes: a power supply; a Near Field Communication (NFC) antenna to receive NFC signals; a Radio Frequency (RF) rectifier electrically coupled to the NFC antenna to generate a current based on a signal received from the NFC antenna; and an electronic switch coupled between the power supply and a sensor, wherein the RF rectifier is further coupled to the switch to apply the current to the switch to change a state of the switch.
