Abstract
Wireless energy transfer devices and systems for medical environments include, in at least some implementations, a wirelessly powered surgical device including: a device resonator configured to generate an oscillating voltage from a captured oscillating magnetic field; and a surgical tool electrically coupled to the device resonator, the surgical tool having a functional output that is capable of being directly powered by the oscillating voltage, and the surgical tool having a rechargeable battery backup; wherein the oscillating voltage is at least 30 volts and has a frequency of at least 1 kHz. Wireless energy transfer is utilized to eliminate cords and power cables from operating instruments and electronic equipment, facilitating mobility.
