Design of Image Transmission System of Intra-Body Communication Based on Capacitive Coupling

In this paper, a system of the intra-body communication (IBC) based on capacitive coupling is designed for transmitting image data. The system comprises of a transmitter and a receiver, which are powered by separate batteries to avoid short grounding. The transmitter uses a complementary metal oxide semiconductor (CMOS) sensor to capture images, an field-programmable gate array (FPGA) is used to encode and modulate the image data, and the data is coupled into the body by an IBC electrode at a lower power. The receiver demodulates the data, then synchronize and decode the data by the FPGA, and finally display the received image on a display. Our experimental results demonstrate that the designed can transmit image data via single body channel and handshake channel, which will lay a foundation for the application of the IBC technology.
