Top Electrical Machinery, Apparatus, Energy Patent – Wireless non-radiative energy transfer – US7741734

U.S. Patent 7741734 was awarded to Massachusetts Institute of Technology on 2010-06-22 and describes a “Wireless non-radiative energy transfer.” This patent has been cited 412 times by other U.S. patents which places it in the top 500 cited patents since 2010 according to our law firm research, and makes it of the most innovative electrical machinery, apparatus, energy patents in the field of electrical engineering. The abstract states:

The electromagnetic energy transfer device includes a first resonator structure receiving energy from an external power supply. The first resonator structure has a first Q-factor. A second resonator structure is positioned distal from the first resonator structure, and supplies useful working power to an external load. The second resonator structure has a second Q-factor. The distance between the two resonators can be larger than the characteristic size of each resonator. Non-radiative energy transfer between the first resonator structure and the second resonator structure is mediated through coupling of their resonant-field evanescent tails.
