Connecting the Future: Energy-Efficient and Environmentally Resilient Transceivers for Body Channel Communication

Body-Channel Communication (BCC) has emerged as a promising interconnect technology in Wireless Body-Area Networks (WBANs), offering advantages such as low transmission loss and enhanced physical security. This tutorial provides a comprehensive overview of BCC transceivers (TRXs), beginning with the fundamental principles of BCC and channel modeling techniques. It then delves into design methodologies for highly energy-efficient and environmentally robust TRX circuits, covering both narrowband and wideband implementations. Additionally, measurement techniques and future research directions will be explored. This tutorial aims to equip designers of wearable healthcare SoCs and other low-power WBAN devices with practical insights and technical expertise.
