使用人体作为传输介质的体内通信可以在不向周围环境发射无线电波的情况下进行无线通信。在1kHz到1000kHz频率范围内信号传输增益的实验结果表明，发射器和接收器的两个电极中只有一个电极贴附在人体上的二电极布置比所有四个电极都贴在人体上的四电极布置具有更大的增益。此外，基于两种不同电极布置的四端电路模型计算的增益与经验结果一致。使用为此目的制造的 10.7 MHz 体内正弦波发射器和接收器来研究这些四端电路模型在 MHz 频段的有效性。结果还表明，两电极布置比四电极布置更适合高速体内通信设备。两个人之间的体内通信可以通过握手来建立，这有许多实际应用，例如在可穿戴电脑之间交换个人数据或电子现金。 (c) 2006 Elsevier B.V. 保留所有权利。
Intrabody communication using the human body as the transmission medium enables wireless communication without emitting radio waves into the surrounding environment. Experimental results on signal transmission gain in the frequency range from I to 1000 kHz have shown that the two-electrode arrangement, in which only one of the two electrodes of the transmitter and receiver are attached to the human body, has greater gain than the four-electrode arrangement, in which all four electrodes are attached to the human body. In addition, calculated gains based on four-terminal circuit models of two different electrode arrangements agree with empirical results. The validity of these four-terminal circuit models in the MHz frequency band was investigated using a 10.7-MHz intrabody sine-wave transmitter and receiver fabricated for this purpose. The results also indicate that the two-electrode arrangement is more suitable for high-speed intrabody communication devices than the four-electrode arrangement. Intrabody communication between two persons can be established by shaking hands, which have numerous practical applications, such as the exchange of personal data or e-cash among wearable PCs.
