Intra-body communication (IBC) uses the conductive human body as the communication channel for data exchange. As the bio-sensor research is moving towards portable, wearable and implantable designs, IBC has significant potential applications for personal health care. Previous IBC research mainly focused on the electromagnetic (EM) IBC scheme, which resulted in low data rate (kbps). In this paper, we systematically studied the electric field (EF) IBC scheme, which enables 10Mbps data rate. The human body channel is thoroughly measured with attenuation, noise and distortion for the IBC application. High speed EF IBC links are tested with various modulation schemes. The minimum transmission power of different links is measured.
体内通信（IBC）利用人体的导电性作为数据交换的通信通道。随着生物传感器研究朝着便携式、可穿戴和可植入设计方向发展，IBC在个人医疗保健领域具有重要的潜在应用。以往的IBC研究主要集中在电磁（EM）IBC方案上，该方案导致数据速率较低（kbps）。在本文中，我们系统地研究了电场（EF）IBC方案，该方案可实现10Mbps的数据速率。针对IBC应用，对人体通道的衰减、噪声和失真进行了全面测量。使用各种调制方案对高速EF IBC链路进行了测试。测量了不同链路的最小发射功率。
