GE’s Battery-Free Sensor is a Breakthrough in RFID Technology

GE’s new battery-free sensor could be just the kick in the pants RFID needs to start living up to its potential. The platform uses a conventional RFID tag coated with a chemically or biologically sensitive film that draws power wirelessly from a handheld reading device. Naturally, eliminating on-board batteries means that manufacturers can make smaller sensors (as you can see in the image above) at a lower cost. So, with any luck, this technology will lead to new tracking and info-swapping applications across a wider range of industries. [Gizmag]
