Ok that is fun. Of course its pretty easy to make an FM transmitter, but doing it with Graphene seems pretty cool. I expect this is pretty directly applicable to small RFID tags that you can read at a distance. Basically beam a 2.4Ghz signal at them, have it rectify that for power and return signal at 900Mhz or so (if you wanted to keep it all in the unlicensed bands). |
