Battery-less computers can be reprogrammed wirelessly
Computation RFID is a small device which converts ambient energy (from nearby radio transmissions) to communicate and obtain power for computing. Their size and perpetual lifetime allows them to be embedded in anything, living organisms included, once for the entire lifetime. And now, for the first time, a team of researchers from Delft University of Technology (TU Delft, The Netherlands) and University of Washington demonstrated that battery-less computers can be reprogrammed wirelessly.
Adapting popular communication protocol used in billions of RFID tags, it is now possible to change completely the functionality of a battery-less computer wherever it is hidden/implanted/sealed without damaging the tissue or a building wall, for instance.
Developed protocol, named Wisent, brings closer a vision of completely autonomous, software defined sensors, battery-less cloud storage and bi-directional battery-less communication.
Results on this work was presented this April at the IEEE INFOCOM conference in San Francisco.
