Electro Quasi-Static Human Body Communication (EQS-HBC) is an emerging communication technique that utilizes the conductive medium of the human body to achieve enhanced energy efficient and physically secure communication in comparison to traditional radio wave-based technologies like Bluetooth. This work presents 1) a thorough characterization of interference on the human body in day-to-day life and 2) develops a human body interference coupling biophysical model. The measurements provided in this paper can serve as a guide for device designs or future EQS-HBC studies as it provides understanding into coupling modalities of interference and accurate interference measurement techniques. read more
