摘要：
人体通信（Human Body Communication, HBC）作为无线体域网（WBAN）的一种替代方案而出现，推动了体积小、能效高且更安全的可穿戴和植入式设备的发展，这些设备在人体内及人体周围构成网络。以往研究表明，尽管HBC相比WBAN更安全，但HBC在10MHz以上频段的电磁（EM）辐射特性使信息容易被窃听。此外，由于40–400MHz范围内的人体天线效应，人体可能会拾取干扰。与之相对，HBC的电准静态（electro-quasistatic, EQS）模式通过使信号被限制在人体内部，为10MHz以下频段的隐蔽数据传输提供了一种有吸引力的方式。然而，目前对该频段内干扰的机制和来源仍缺乏认识，而这对于正确选择数据传输频段至关重要。本文解释了EQS频段中的干扰耦合模态及其可能来源。可穿戴设备在实际场景中所经历的干扰是一个非平凡问题；为此，本文设计了合适的EQS HBC测量装置，通过采用具有小接地平面、尺寸与可穿戴设备相当的测量装置来重现该干扰。本文首次提出了人体生物物理干扰拾取模型，并展示了在不同环境设置下，使用可穿戴设备在最高250kHz频率范围内获得的干扰测量结果。
英文摘要：
The emergence of Human Body Communication (HBC) as an alternative to wireless body area networks (WBAN) has led to the development of small sized, energy efficient and more secure wearable and implantable devices forming a network in and around the body. Previous studies claim that though HBC is comparatively more secure than WBAN, nevertheless, the electromagnetic (EM) radiative nature of HBC in >10MHz region makes the information susceptible to eavesdropping. Furthermore, interferences may be picked up by the body due to the human body antenna effect in the 40-400MHz range. Alternatively, electro-quasistatic (EQS) mode of HBC forms an attractive way for covert data transmission in the sub 10MHz region by allowing the signal to be contained within the body. However, there is a gap in the knowledge about the mechanism and sources of interference in this region (crucial in allowing for proper choice of data transmission band). In this paper, the interference coupling modality in the EQS region is explained along with its possible sources. Interferences seen by the wearable in the actual scenario is a non-trivial problem and a suitable measurement EQS HBC setup is designed to recreate it by employing a wearable sized measurement setup having a small ground plane. For the first time, a human biophysical interference pickup model is proposed and interference measurement results using a wearable device are presented up to 250kHz in different environmental settings.
