Energy-efficient Body-channel Communication for Distributed Flexible Sensors

Abstract

The combination of body channel communication (BCC) and flexible electronics has potential to realize long-term, accurate and secure monitoring of the distributed vital signs. In this work, we demonstrate a BCC system, which employs OOK modulation and UART protocol to reduce the system complexity. And a redundancy correction method is adopted to reduce the probability of collision during N-to-1 communication. The maximum data rate achieves 100 kbps during experiment.
