Abstract: A method of powering a wireless autonomous device having energy harvesting circuitry, on-board electronic circuitry, and RF transmitter circuitry using an RF transmitting profile that includes a plurality of RF pulses. That same profile may also be used to simultaneously communicate information to the wireless autonomous device in a number of ways, including different encoding schemes. A system including a plurality of wireless autonomous devices that employs the methods is also provided. Further, a method of designing a wireless autonomous device system and/or a wireless autonomous device to be used therein is provided that employs an equivalent circuit for the wireless autonomous device that is in the form of a lumped parameter RLC circuit with an energy source.
