Unlimited, stable, and reliable power is an assumption upon which most traditional computing systems and abstractions are designed. This project explores new techniques and tools for developing sophisticated sensing applications that do not rely on batteries and are powered by a variety of environmental energy sources. Replacing batteries with capacitors has many advantages for system designers. Capacitors have smaller size, lower cost, and the potential for deployments lasting decades longer than batteries - which wear out after two to five years. But even with energy harvesting advances, current capacitor-based devices are difficult to program, test, and deploy due to fluctuating energy supplies, limited energy storage, and frequent loss of power. This project will explore and prototype hardware techniques, software systems, programming languages, and tools that will enable application designers to quickly prototype sophisticated applications, focusing on application goals instead of avoiding and recovering from power failures. This project focuses on a research agenda to: 1) design and develop a novel computing platform specifically for transiently-powered sensing devices; 2) prototype techniques for managing harvested energy in hardware in order to simplify software design; 3) develop a new programming model that allows programmers to represent applications in a simple disruption-tolerant form; 4) develop runtime techniques that schedule computing tasks in order to work effectively towards achieving application goals in spite of unpredictable power outages; 5) create novel tools that help developers predict how their transiently-powered applications will perform when deployed; and 6) evaluate these contributions in the context of real pilot deployments. The project, which includes broad k-12 outreach, will provide experiences conducting innovative research and working with biologists and other domain scientists for graduate and undergraduate students around the development of devices that provide useful data for decades in spite of frequent power failures while providing.

无限、稳定和可靠的功率是设计大多数传统计算系统和抽象的假设。该项目探索新的技术和工具，用于开发不依赖电池的复杂传感应用，并由各种环境能源供电。 用电容器代替电池对系统设计人员有很多好处。电容器体积更小，成本更低，部署时间可能比电池长几十年-电池在两到五年后就会磨损。但是，即使在能量收集方面取得了进展，由于能源供应波动、能量存储有限以及经常断电，目前基于电容器的设备也难以编程、测试和部署。该项目将探索和原型硬件技术，软件系统，编程语言和工具，使应用程序设计人员能够快速原型化复杂的应用程序，专注于应用程序目标，而不是避免和从电源故障中恢复。 该项目的研究重点是：1）设计和开发一种专门用于瞬时供电传感设备的新型计算平台; 2）在硬件中管理收集能量的原型技术，以简化软件设计; 3）开发一种新的编程模型，允许程序员以简单的中断容忍形式表示应用程序; 4）开发调度计算任务的运行时技术，以便在不可预测的停电情况下有效地实现应用目标; 5）创建新颖的工具，帮助开发人员预测他们的瞬时供电应用在部署时将如何执行;以及6）在真实的试点部署的背景下评估这些贡献。该项目，其中包括广泛的k-12外展，将提供经验进行创新研究，并与生物学家和其他领域的科学家为研究生和本科生围绕设备的发展，提供有用的数据，尽管几十年来频繁的电源故障，而提供工作。
