N2 - In this paper, we present an audio transmission system based on capacitive coupling intra-body communication (IBC). The system consists of a transmitter and a receiver, which are powered by separate batteries. In the transmitter, Field Programmable Gate Array (FPGA) is used to encode and modulate the digital audio data. The data is converted into analog signal and finally coupled into the human body by the IBC electrode. In the receiver, signal transmitting within human body is detected by the IBC electrode and converted into digital data. An FPGA is used to demodulate, synchronize and decode the data, and finally the data is recovered to the sound signal by audio chip. Our experiments show that the system can continuously transmit data at the rate of 1536 kbps on the human body, which lays a foundation for the application of IBC technology in wireless headphones.
