I saw an interesting article this morning about wireless charging that got me thinking about its possible use in industrial sensing. This technology is being developed by a MIT spin-off WiTricity and it's new partner MediaTek. The wireless charging they are working with is a big step beyond the inductive type charging plates that are currently on the market but, instead can charge devices at a distance. Obviously a cell phone that never needs charging and, perhaps, a much smaller battery geography would be a big deal on the consumer market but I'm thinking it could be a game changer in industrial settings.
Using wireless data transmission solves a lot of sensing problems particularly in equipment that has a lot of moving parts but that still leaves the problem of powering the device. Newer sensors with ultra low power demand and advanced long-life batteries solve some of this but, I suspect that they still leave some sense of concern that a dead sensor battery could idle an entire production line. Some of this concern could be alleviated by energy harvesting and/or solar technology but these are not ideal in all cases. But, if you could eliminate much of the battery size, combine energy harvesting and WiFi type power, you could have a really small wireless sensor that would be ultra-reliable. To me that's a pretty big deal.
