A system and method for wirelessly powering an electrosurgical device using a generator to generate a radio frequency (RF) energy field. A switch on the electrosurgical device sends a wireless signal to the generator, where the generator allows a current to pass through an inductive coil to generate the RF energy field. The RF energy field induces a current to flow across an inductive coil within the electrosurgical device. The current flow is then processed through a RF conditioning circuit and outputted to the end effector assembly of the device.
