CSR: Medium: Systems Abstractions for Self-Powered Smart Textiles

无处不在计算的一个令人兴奋的新方向是将传感器和用户界面元素直接编织到纺织品中的能力。最近的进展已经证明了几种功能，包括能量收集、传感、通信和使用涂有不同聚合物的线程的相互作用。但是，集成这些不同元素的智能纺织品的设计在硬件设计、软件架构和可处理能量变化的自适应算法设计方面提出了挑战。该项目的目标是开发系统原理和构建模块，以实现这种基于自供电纺织品的传感应用。该项目旨在设计一种自供电、基于纺织品的全身传感和交互系统，该系统是无负担和非侵入性的。我们描述了一个垂直集成的堆栈，包括线程级优化、硬件架构设计和运行时系统，以实现我们的愿景。该项目有四个重点：(a)优化基于纺织品的能量收集和传感的方法；(b)基于收割的模块化纺织品的系统架构；(c)自供电纺织品的运行系统；(d)养老环境下应用驱动的评价与表征。这项工作为未来的智能纺织品提供了基础，可以实现真正无处不在的智能计算和传感。我们工作中的使能技术将影响一系列应用，包括人机交互、健康和保健、体育分析和制造业。该项目将为斯普林菲尔德技术社区学院科学、技术、工程和数学（STEM）入门学院的学生提供指导和实习机会，以加强化学和计算机领域代表性不足的学生的数量。该项目还将与马萨诸塞州霍利奥克的girls Inc.合作，为中学女生举办年度研讨会；这些讲习班已经举办了好几年，并将根据该项目的工作继续提供新的模块。作为这个项目的结果产生的所有数据，包括跟踪数据、软件代码、模拟数据和出版物，将在项目存储库中公开提供：http://sensors.cs.umass.edu/projects/textile/。数据和由此产生的研究成果将在项目结束后用适当的方法保存至少五年。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

An exciting new direction for ubiquitous computing is the ability to weave sensors and user interface elements directly into textiles. Recent advances have demonstrated several capabilities including energy harvesting, sensing, communication, and interaction using threads coated with different polymers. But the design of smart textiles that integrate these different elements presents challenges in hardware design, software architecture, and in the design of adaptive algorithms that can deal with energy variability. The project objective is to develop the systems principles and building blocks to enable such self-powered textile-based sensing applications. This project seeks to design a self-powered, textile-based whole body sensing and interaction system that is burden-free and non-intrusive. We describe a vertically integrated stack including thread-level optimizations, hardware architecture design, and run-time systems to enable our vision. The project has four thrusts: (a) methods to optimize textile-based energy harvesting and sensing; (b) system architecture for modular harvesting-based textiles; (c) runtime systems for self-powered textiles; and (d) application-driven evaluation and characterization in the context of elder care. This work provides the foundations for future smart textiles that can enable truly ubiquitous smart computing and sensing. The enabling technologies in our work will impact a range of applications including human computer interactions, health and wellness, sports analytics, and manufacturing. The project will provide mentoring and internship opportunities for students at the Science, Technology, Engineering and Math (STEM) Starter Academy at Springfield Technical Community College to fortify the number of underrepresented students in chemistry and computing. This project will also support an annual workshop for middle school girls in partnership with Girls Inc. of Holyoke, MA; these workshops have been held for several years, and will continue with new modules based on the work on this project. All data produced as a result of this project, including trace data, software code, simulation data, and publications, will be made publicly available at the project repository: http://sensors.cs.umass.edu/projects/textile/. The data and the resulting research outputs will be maintained using appropriate methods for at least five years after the end of the project.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.
