An exciting new paradigm for wearable health sensors is one where sensors and batteries need not be integrated within the same device. This project seeks to realize this vision by utilizing human tissue as a medium for transferring power and data between different device pairs. The project objective is to develop hardware and software mechanisms that allow heterogeneous networks of sensors that are largely battery-free. The key working principle is the design of a system where energy transmitters that include batteries, provide power to relatively many battery-free sensors while simultaneously serving as an endpoint for data collection from the sensors. The project has three thrusts: 1) quantifying the performance and safety issues of the use of human tissue as a propagation medium for power and communications; 2) the design of hardware and software primitives needed to facilitate energy sharing between networks of battery-free devices; 3) the operating system, run-time support, and tools needed to coordinate devices that in turn enable higher level health applications.The technologies developed in this work will impact a range of potential health applications including remote rehabilitation, nutrition monitoring, and other real-time sensing tasks enabled by distributed sensors worn for long time periods. The technologies developed as part of this project have the potential to greatly optimize the design of the wearable health sensors themselves. Additionally, the elimination of batteries in remotely powered sensors will eliminate the growing waste stream that is a consequence of battery wear out. Outcomes of this project will be integrated into a number of ongoing outreach activities that expose K-12 and undergraduate students to the potential benefits of wearable health technologies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

可穿戴健康传感器的令人兴奋的新范式是传感器和电池不必集成在同一设备中的一种。该项目试图通过利用人体组织作为传输功率和不同设备对之间数据的媒介来实现这一愿景。该项目的目标是开发硬件和软件机制，这些机制允许在很大程度上无电池的传感器网络。关键的工作原理是设计系统的设计，其中包括电池在内的能量发射器，为相对无电池传感器提供电源，同时用作传感器数据收集的终点。该项目具有三个推力：1）量化使用人体组织作为电力和通信的传播媒介的性能和安全问题； 2）所需的硬件和软件原始功能的设计，以促进无电池设备网络之间的能源共享； 3）操作系统，运行时间支持以及协调设备所需的工具，而设备又可以实现更高级别的健康应用程序。这项工作中开发的技术将影响一系列潜在的健康应用程序，包括长期佩戴的分布式传感器启用了远程康复，营养监测以及其他实时感应任务。作为该项目的一部分开发的技术有可能极大地优化可穿戴健康传感器本身的设计。此外，消除远程动力传感器中的电池将消除不断增长的废物流，这是电池磨损的结果。该项目的成果将集成到许多正在进行的外展活动中，这些活动将K-12和本科生暴露于可穿戴健康技术的潜在好处。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响来评估来获得支持的。
