A high speed wearable system for body coupled communication

[摘要] There are currently no ideal methods by which doctors can read bodily signals detected by implanted devices. Methods are either too high power for long-term implants, such as radio transmission, or pose health threats to the patient, such as connection ports piercing the skin. However, a novel method of transmitting and receiving electronic sensor data is emerging known as body coupled communication (BCC). This method of communication utilizes the inside of the body;;s low impedance at frequencies on the order of 100 MHz to send signals over that channel and receive the signals at another location on the body. It is also a lower power and more secure wireless option than radio transmission. This thesis presents a 3 Mbps wearable receiver and transmitter system for BCC that was developed from commercially available electrical components and a custom PCB. Both receiver and transmitter are on the same PCB. They share a digital FPGA system, but have separate analog signal conditioning sections on the board.
