Sony is patenting a new technique that enables wireless power exchange between nearby devices, including smartphones, computers, microwave, washing machine, fridges, and TVs. The patent doesn’t detail how well this technology would actually work and has no word over the distance for which this technology might work between two devices. It doesn’t specify that these devices would necessarily be smartphones or computers; instead, it uses the term “portable consumer electronic device” The patent does not necessarily mean we will ever see the idea come to life, but if succeeded, your phone will automatically start charging while you walk into a room.
