I know it's possible to transmit power over very short distances with 2 pieces of coiled wire.
I don't know the science behind it,but I'm assuming that even if you applied a DC input you would get an AC output that would need rectifying for a DC circuit.
Is it possible to modulate and demodulate this?
I'm thinking along the lines of FSK rather than OOK/ASK due to the receiver being powered by the transmitter.
I would have considered NFC, but I need to supply about 200mA at 5v and I only need to transmit a few bytes of data.
