体内通信是一种在可穿戴电子传感器和设备之间在个人局域网(PAN)内交换信息的无线手段。通过对信号在人体内传播的多次实验，证实了体内通信的可行性，并设计了一个人体体模，通过反复实验获得了可重复性的结果。在这些实验结果的基础上，构建了一个工作在10.7 MHz调频(FM)频段、由3V直流电源供电的铝电极传输系统。该样机被证明能够在存在外部噪声的情况下通过人体对象传输模拟信号。使用新制造的10.7 MHz频移键控(FSK)发射器和接收器设备也实现了9600bps的数字数据传输。10.7兆赫的载频是调频无线电接收器的中频，这意味着建议的系统可以利用多种廉价的商业无线电频率设备。
Intra-body communication is a wireless means of exchanging information within a personal area network (PAN) between wearable electronic sensors and devices. The feasibility of intra-body communication is confirmed through several experiments on signal propagation within the human body, and a human phantom is designed and used to obtain reproducible results over repeated experiments. Based on the results of these experiments, a prototype transmission system is constructed using aluminum electrodes powered by 3 V DC and operating in the 10.7 MHz frequency modulation (FM) band. This prototype is demonstrated to be capable of transmitting analog signals through the human subjects in the presence of external noise. Digital data transmission at 9600 bps is also achieved using newly fabricated 10.7 MHz frequency shift keying (FSK) transmitter and receiver devices. The carrier frequency of 10.7 MHz is the intermediate frequency of FM radio receivers, meaning that the proposed system can make use of a wide selection of inexpensive, commercial radio frequency devices.
