Human body communication (HBC) is a wireless transmission method that utilizes the human body as part of the transmission medium. In HBC, a high-frequency signal is transmitted by a current flowing through the body surface and via the near-field electric field around it. Due to the lack of specific equipment and tools to measure HBC transmission characteristics, HBC systems are still in the development...
In order to prototype applications and evaluate characteristics of human body communication (HBC), transmitter/receiver modules were designed. A transmitter module incorporated a direct digital synthesizer (DDS) to provide a modulated signal. A receiver module utilized the 10.7-MHz intermediate frequency part of the low-power radio receiver module. These newly designed modules are compatible with...
