摘要

为人体上、周围和内部的生物传感器提供具有物理安全通信的节能传感是当今低成本医疗保健发展的一个主要研究领域,可实现持续监测和/或安全、永久运行。当这些设备作为节点网络使用时,构成了物联网(IoB),这带来了一些挑战,包括严格的资源限制(功率/面积/计算/内存),同时传感和通信,以及DHS和FDA建议所证明的安全漏洞。另一个主要挑战是找到一种有效的身体能量收集方法来支持传感、通信和安全子模块。由于能量收集量的限制,我们需要减少每单位信息消耗的能量,这使得传感器内分析/处理的使用势在必行。在本文中,我们回顾了低功耗传感、处理和通信方面的挑战和机遇,以及未来生物传感器节点可能的供电方式。具体来说,我们分析,比较和对比(a)不同的传感机制,如电压/电流域与时域,(b)低功耗,安全的通信方式,包括无线技术和人体通信,以及(c)可穿戴设备和植入物的不同供电技术。

Bioelectronic Sensor Nodes for Internet of Bodies
Energy-efficient sensing with Physically-secure communication for bio-sensors on, around and within the Human Body is a major area of research today for development of low-cost healthcare, enabling continuous monitoring and/or secure, perpetual operation. These devices, when used as a network of nodes form the Internet of Bodies (IoB), which poses certain challenges including stringent resource constraints (power/area/computation/memory), simultaneous sensing and communication, and security vulnerabilities as evidenced by the DHS and FDA advisories. One other major challenge is to find an efficient on-body energy harvesting method to support the sensing, communication, and security sub-modules. Due to the limitations in the harvested amount of energy, we require reduction of energy consumed per unit information, making the use of in-sensor analytics/processing imperative. In this paper, we review the challenges and opportunities in low-power sensing, processing and communication, with possible powering modalities for future bio-sensor nodes. Specifically, we analyze, compare and contrast (a) different sensing mechanisms such as voltage/current domain vs time-domain, (b) low-power, secure communication modalities including wireless techniques and human-body communication, and (c) different powering techniques for both wearable devices and implants.
