使用人体作为传输介质的体内通信无需向空气中发射无线电波即可实现无线通信。 1~1000 kHz频率范围内信号传输增益的实验结果表明，仅发射器和接收器的两个电极之一附着在人体上的二电极模型比所有四个电极都附着在人体上的四电极模型具有更大的增益。基于两种不同电极布置的四端电路模型计算的增益与实验结果一致。使用为此目的制造的 10.7 MHz 体内正弦波发射器和接收器研究了 MHz 频段四端电路模型的有效性。结果还表明，两电极模型比四电极模型更适合高速体内通信设备。
Intrabody communication using the human body as the transmission medium enables wireless communication without emitting radio waves into the air. Empirical results on signal transmission gain in the frequency range from 1 to 1000 kHz have shown that the two-electrode model, 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 model, in which all four electrodes are attached to the human body. Calculated gains based on four-terminal circuit models of two different electrode arrangements agree with experimental results. The validity of the 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 model is more suitable for high-speed intrabody communication devices than the four-electrode model.
