The energy efficiency of microelectronics has been improving exponentially for decades. It is becoming possible to operate low power sensing, computing and communication platforms in a perpetual, battery-free fashion, with all power provided by Radio Frequency (RF) signals or other energy harvesting. The Wireless Identification and Sensing Platform (WISP) is an open source battery-free platform that the present investigators originally introduced in 2006. Hundreds of WISPs have been manufactured and distributed to researchers around the world. This infrastructure has enabled research in diverse areas of computer science, including networking, Human-Computer Interaction, Ubiquitous Computing, Robotics, and other areas. The present proposal will allow the researchers to integrate the latest research results, such as Ambient Backscatter Communication, into the WISP family, and also to reap the benefits of the most recent improvements in low power microelectronics. The proposal will allow us to produce a new generation of the infrastructure and mature it to the point that it becomes self sustaining, via sales of hardware or other means. We expect that the sustained infrastructure will support research in backscatter communication, low power systems and networking, and applications of ultra-low-power platforms. Battery-free sensing systems are expected to enable a wide array of new capabilities, which will generate substantial commercial impact in a wide variety of markets.Computing is becoming connected more and more deeply to the physical world, a transformation that can enable smart environments, better medical care, more efficient manufacturing, and more. However, the need to power physically embedded microelectronic systems is a key challenge. This project will allow us to sustain the WISP infrastructure for battery-free, RF-powered computing and communication. The infrastructure will enable research in several areas. In recent years, the PI and co-PI introduced Ambient Backscatter Communication, and backscatter-based WISP cameras, which have been widely recognized in the research community. Making these tools widely available will enable research on topics such as (ambient) backscatter networking, applications of battery-free cameras, and algorithms for interactive compression and computer vision in battery-free camera systems. This research would likely remain inaccessible for a long time to many computer and information science and engineering researchers, since there are no widely accessible platforms that support research on these topics. The sustained infrastructure will also enable novel application research, in areas such as improved human activity detection systems, battery-free input devices, and also research on body-implanted electronics, and long term structural health monitoring.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.

几十年来，微电子的能源效率一直在指数级增长。以永久性，无电池的方式运行低功率传感，计算和通信平台，并使用射频（RF）信号或其他能源收集提供的所有功率。 无线识别和传感平台（WISP）是一个没有开源电池的平台，当前的调查人员最初在2006年推出。数百个WISP已被制造并分发给了世界各地的研究人员。 这种基础设施已使计算机科学不同领域的研究能够进行研究，包括网络，人为计算机的互动，无处不在的计算，机器人技术和其他领域。 本提案将使研究人员能够将最新的研究结果（例如环境反向散射通信）整合到WISP家族中，并从低功率微电学中获得最新改善的好处。 该提案将使我们能够生产新一代的基础架构，并通过硬件或其他方式来使其成熟到自我维持。我们预计，持续的基础架构将支持反向散射通信，低功率系统和网络的研究以及超低功率平台的应用。 预计无电池的传感系统将使各种各样的新功能能够在各种市场中产生重大商业影响。编写越来越深入地连接到物理世界，这种转型可以实现智能环境，更好的医疗保健，更高效的制造业等。但是，为物理嵌入的微电子系统提供动力是一个关键挑战。该项目将使我们能够维持无电池，供电的计算和通信的WISP基础架构。 基础设施将在多个领域进行研究。近年来，PI和CO-PI引入了环境反向散射通信，以及基于反向散射的WISP摄像机，这些摄像头在研究界广泛认可。将这些工具广泛使用将使有关（环境）反向散射网络，无电池摄像机的应用以及用于交互式压缩和计算机视觉的算法等主题的研究。对于许多计算机，信息科学和工程研究人员来说，这项研究可能会在很长一段时间内无法访问，因为没有广泛访问的平台支持这些主题的研究。持续的基础架构还将在改善人类活动检测系统，无电池输入设备以及对人体内置电子设备的研究以及长期结构健康监控等领域进行新的应用研究。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识优点和广泛的crietia crietia的评估来通过评估来进行评估。
