1. A radio identification system, comprising:
a first computing device configured to emit an information radio signal and a wireless power signal;
a second computing device comprising a first antenna tuned to receive the information radio signal, a radio frequency transceiver, a second antenna tuned to receive the wireless power signal, a wireless power receiver, a sensor controller configured with an analog-to-digital converter, and a microcontroller,
wherein the sensor controller converts analog voltage patterns to a digital form;
non-transitory media storing instructions readable by the radio identification system, that when executed by the radio identification system, cause the radio identification system to:
transmit, by the first computing device, a plurality of wireless power signals;
receive, at the second antenna of the second computing device, the plurality of wireless power signals;
harvest, by the wireless power receiver associated with the second antenna, energy from the received plurality of wireless power signals;
determine, by the sensor controller, an identifier corresponding to an energy pattern of a combination of the received plurality of wireless power signals and
if the identifier matches an identifier associated with the second computing device, initiate a sensor controller interrupt instruction to the microcontroller to transition the microcontroller from a sleep state into a power consuming state wherein the microcontroller in the power consuming state is configured to receive the information radio signal.
