1. A reception (RX) node using mutual resonance, the RX node comprising:
- a target resonator configured to receive power via mutual resonance with a source resonator;
a sensor configured to sense information in response to the received power;
a controller configured to, in response to the received power;
generate a data packet comprising the sensed information; and
transmit the data packet to the source resonator via the target resonator at a timing selected to prevent the RX node from colliding with any other RX node.

Abstract
A reception (RX) node using mutual resonance includes a target resonator configured to receive power via mutual resonance with a source resonator; a controller configured to wake up in response to the received power, determine a point in time at which the controller woke up to be a point in time at which synchronization with other RX nodes is performed, and generate a data packet, and a sensor configured to wake up in response to the received power, sense information.
