Cheap, washable, and battery-free RFID tags could form the basis for a new type of wearable sensor.
Radio-frequency identification (RFID) tags have become a key component of global commerce, enabling stakeholders to track physical assets quickly and reliably. Deployed properly, the tags could be used in a new class of wearable designed to track physical movement and shape change.
Researchers at Carnegie Mellon University have figured out how RFID tags could be used do things like control virtual avatars or tell slouching users to sit up straight.
RFID tags are cheap, battery-free and washable, which makes them appealing to developers.
“By attaching these paper-like RFID tags to clothing, we were able to demonstrate millimeter accuracy in skeletal tracking,” says Haojian Jin, a Ph.D. student in CMU’s Human-Computer Interaction Institute (HCII).
