本文描述了一种用于体内通信的近场传感收发器，其中人体是传输介质。收发器的关键部件是由电光晶体和激光实现的电场传感器。该传感器具有极高的输入阻抗，适合于检测人体产生的微小且不稳定的电场。该收发器能够在双手之间约150 cm的操作范围内通过人体进行10 Mb/s的IEEE 802.3半双工通信。在数据包大小为1070个八位字节时，获得了0.04%的数据包错误率。本文介绍了收发器的配置和性能，并提出了通信测试的结果。
This paper describes a near-field-sensing transceiver for intrabody communication, in which the human body is the transmission medium. The key component of the transceiver is an electric-field sensor implemented with an electrooptic crystal and laser light. This sensor is suitable for detection of the small and unstable electric fields produced by the human body because it has extremely high input impedance. This transceiver enables IEEE 802.3 half-duplex communication of 10 Mb/s through a person's body in an operating range of about 150 cm between the hands. The packet error rate of 0.04% is obtained at packet size of 1070 octet. This paper explains the configuration and performance of the transceiver and presents results of a communication test.
