Researchers devise wireless power scheme for charging devices anywhere in a room
You may someday be able to just walk into a room and have your mobile device recharge while it sits in your pocket if researchers from Disney Research perfect their new charging-at-a-distance scheme. They say quasistatic cavity resonance (QSCR) can let special structures such as cabinets, rooms, and warehouses, generate magnetic fields that safely deliver […]
Cryptographic authentication could be coming to wireless chargers
Researchers from the Massachusetts Institute of Technology’s Microsystems Technology Labs have built a chip that blocks attempts to wireless charging unless the charger first provides cryptographic authentication. The MIT researchers say their work is in response to a counterfeit goods problem that now plagues consumer electronics. The researchers presented the new chip at the recent […]
