Abstract: Red Acton is an exciting new technology for human area networking. We have developed a transceiver that uses the human body as a data transmission medium based on an electric-field sensor that uses an electrooptic crystal and laser light. Using this transceiver, we succeeded in achieving 10BASE communication in accordance with IEEE 802.3 through a human body from one hand to the other hand. While our immediate objective is to implement a Red Tacton system supporting two-way intra body communication at a rate of 10 M bit/s between any two points on the body, our longer-term plans include developing a mass-market transceiver interface supporting PDA’s s and notebook computers while continuing efforts to reduce the size and power consumption of the transceiver to enhance its portability. In the past, Bluetooth, infrared communications (IrDA), radio frequency ID systems (RFID), and other technologies have been proposed to solve the "last meter" connectivity problem. However, they each have various fundamental technical limitations that constrain their usage, such as the precipitous fall-off in transmission speed in multi-user environments producing network congestion. Thus this problem has been solved by the red tacton and has made it very innovative.
