This project aims to develop software and hardware techniques required to distribute intelligent computations across a network of batteryless, intermittent sensor nodes. Rather than relying on traditional ultra-low-power chips that assume they have ready access to bulk energy (e.g., wired power or a battery), the project investigates approaches where nodes operate using power supplied solely by energy harvested from their operating environment and, thus, spend a significant fraction of time without sufficient power to operate at all. Specifically, the project focuses on investigating the following novel directions: (1) adaptive hardware design techniques to support a responsive, communication- and energy-harvesting-driven paradigm; and (2) application-specific computation scheduling approaches to efficiently offload computation across a network of batteryless, intermittent sensor nodes.Liberating batteryless, intermittent sensor nodes from needing to be closely-connected to a computationally-capable device (e.g., edge server or data-center) fundamentally extends their potential for impact in fields such as industrial automation, infrastructure monitoring, agriculture, environmental sciences, healthcare, defense, and space exploration. Indeed, the results of the project can benefit any field that needs pervasive long-duration intelligence at the edge that remains robust to poor or limited connection to cloud infrastructure. An inherent aspect of this project is a co-curricular experience that promotes students to follow the entire design process of a chip, thus replicating the real-world complexity of computer chip design as well as facilitating student leadership, ownership, and interpersonal skills in preparation for internships and the workforce. The resulting software and hardware systems, experimental data, and educational prototypes from this project will be made publicly available for scientists, engineers, educators, and industry to use.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.

该项目旨在开发在无电池、间歇性传感器节点网络中分配智能计算所需的软件和硬件技术。而不是依赖于传统的超低功耗芯片，假设他们已经准备好获得大量的能量（例如，有线电源或电池），该项目研究了节点仅使用从其操作环境中收集的能量提供的电源进行操作的方法，因此，在没有足够电源的情况下花费很大一部分时间来操作。具体而言，该项目侧重于研究以下新的方向：（1）自适应硬件设计技术，以支持响应，通信和能量收集驱动的范例;以及（2）应用特定的计算调度方法，以在无电池、间歇性传感器节点的网络上有效地卸载计算。间歇传感器节点不需要紧密连接到具有计算能力的设备（例如，边缘服务器或数据中心）从根本上扩展了其在工业自动化、基础设施监控、农业、环境科学、医疗保健、国防和空间探索等领域的影响潜力。事实上，该项目的结果可以使任何需要在边缘处普及长期智能的领域受益，这些智能对于与云基础设施的不良或有限连接保持稳健。该项目的一个固有方面是一个共同的课程体验，促进学生遵循芯片的整个设计过程，从而复制计算机芯片设计的现实世界的复杂性，以及促进学生的领导力，所有权和人际交往能力，为实习和劳动力做准备。该项目产生的软件和硬件系统、实验数据和教育原型将公开提供给科学家、工程师、教育工作者和工业界使用。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
