The present invention relates to a device and a method to supply power and transmit data through body-combined communication. According to the present invention, in a device to supply power and transmit data through body-combined communication, when bio data need to be collected, RX supplies power to TX, which does not include an extra power supply, through the body-combined communication so that the TX is operated, and the operated TX collects the bio data to transmit the data to the RX. According to the present invention, a sensor node (TX) is manufactured as small and light as possible so that a wearer of the invention is not constrained by weight or volume, and especially, when multiple electrodes for TX and RX are applied to a human body, only the TX, which is selected for each of the electrodes at an intended timing, is able to be activated by power supply so that only a single channel is formed at a specific moment. Thus, cross talk, caused by the mixture of various channels, is prevented, and the RX relays multichannel communication to maximize the utilization of the body-combined communication. |
