Detailed in a new study published in Nature Electronics, the technology can deliver 50 watts of power using magnetic fields.
Study author Alanson Sample, U-M professor of computer science and engineering, says that in addition to untethering phones and laptops, the technology could also power implanted medical devices and open new possibilities for mobile robotics in homes and manufacturing...
