A 2Mbps Human Body Communication Transceiver Based on Body Antenna Effect

Abstract

This paper presents a human body communication (HBC) transceiver for wireless body network applications. The transceiver employs on frequency shift keying (FSK) modulation and operates in 40 MHz–60 MHz which is the resonant frequency of the human body as an antenna. It achieves high performance and stability through establish passive microstrip line and via models and active device-models. The proposed transceiver is designed and fabricated by FR4 printed circuit board (PCB) process, the transceiver has the ability of configurable data rate up to 2 Mbps and it achieves –86 dBm receiving sensitivity at 2 Mbps data rate. Meanwhile, the transceiver output power dynamics range is 34 dB. Furthermore, with a visual interaction interface, the transceiver can be agility use in a variety of scenarios. Its measurements are verified on human body. The result shows that the transceiver has ability to send data from person to person by relying on human body antenna radiation. The transceiver shows great prospect in wireless body area networks (WBAN) for telemedicine and emergency communication.
