遵循摩尔定律，经过50年的持续小型化，随着廉价计算的到来，可穿戴设备正变得越来越流行。这些可穿戴设备通常使用无线体域网络(WBAN)互连。人体通信(HBC)通过使用人体作为传导介质，在身体可穿戴设备之间提供了一种替代的节能通信技术。由于更低的损耗和宽带信令，这使得通信功率比WBAN低数量级。此外，HBC比WBAN安全得多，因为信息包含在人体内，除非身体接触，否则无法窥探。在本文中，我们重点介绍了HBC的应用：(1)社交网络(例如，在会议/聚会中握手时发送的LinkedIn/Facebook好友请求)，(2)使用人机或人机动态HBC的安全认证，以及(3)使用人内HBC的超低功耗、安全的BAN。HBC最大的技术瓶颈之一是人体像天线一样接收到的干扰(例如调频)。在这项工作中，我们首次介绍了一种积分双数据速率(DDR)接收器技术，该技术允许对干扰进行陷波滤波(>；20分贝)，以实现干扰稳健的HBC。
With the advent of cheap computing through five decades of continued miniaturization following Moore's Law, wearable devices are becoming increasingly popular. These wearable devices are typically interconnected using wireless body area network (WBAN). Human body communication (HBC) provides an alternate energy-efficient communication technique between on-body wearable devices by using the human body as a conducting medium. This allows order of magnitude lower communication power, compared to WBAN, due to lower loss and broadband signaling. Moreover, HBC is significantly more secure than WBAN, as the information is contained within the human body and cannot be snooped on unless the person is physically touched. In this paper, we highlight applications of HBC as (1) Social Networking (e.g. LinkedIn/Facebook friend request sent during Handshaking in a meeting/party), (2) Secure Authentication using human-human or human-machine dynamic HBC and (3) ultra-low power, secure BAN using intra-human HBC. One of the biggest technical bottlenecks of HBC has been the interference (e.g. FM) picked up by the human body acting like an antenna. In this work for the first time, we introduce an integrating dual data rate (DDR) receiver technique, that allows notch filtering (>20 dB) of the interference for interference-robust HBC.
