ITR: Tailor-Made: Design of e-Textile Architectures for Wearable Computing

[0219809] thomas L. martina Poly研究所：可穿戴计算技术具有随时随地获取信息的潜力。可穿戴计算的三个主要目标是允许用户在持续佩戴设备的情况下进行正常的日常工作，对用户周围的人不可见，并意识到用户。S动作和位置。本研究的目的是研究电子纺织品（e-纺织品）的可穿戴计算用途，这是一种新颖的硬件/软件平台，有可能解决实现这些目标的许多问题，并为基于电子纺织品的可穿戴计算创造一个设计环境。电子纺织品是一种将电子设备和互连编织在其中的织物。电子设备由通用微处理器、数字信号处理器、传感器和执行器组成，在整个织物中有规律地间隔。电子纺织品允许创建具有物理灵活性和尺寸的系统，这是目前可用的电子制造技术无法实现的。组件和互连是织物的一部分，因此不太显眼，更重要的是，不容易缠在一起或被周围的环境卡住。因此，电子纺织品可以在日常情况下穿着，而目前可用的可穿戴计算机会阻碍用户。电子纺织品还具有更大的灵活性，可以适应应用程序的计算和传感要求的变化，以管理功耗和上下文感知。传感器和处理元件的数量和位置可以根据用户和应用的当前需求动态定制，而不是在设计时固定。

ABSTRACT 0219809Thomas L. MartinVa Poly Inst. Wearable computing has the potential to allow access to information anytime and anyplace. Three of the major goals of wearable computing are to allow the user to go about a normal daily routine while constantly wearing a device, to be invisible to those around the user, and to be aware of the user.s actions and location. The purpose of this research is to investigate the wearable computing uses of electronic textiles (e-textiles), a novel hardware/software platform that has the potential to solve many of the problems in achieving these goals, and to create a design environment for e-textile-based wearable computing. E-textiles are fabrics that have electronics and interconnections woven into them. The electronics consist of general-purpose microprocessors, digital signal processors, sensors, and actuators at regular intervals throughout the fabric. E-textiles allow the creation of systems with a physical flexibility and size that cannot be achieved with currently available electronic manufacturing techniques. Components and interconnections are a part of the fabric and thus are much less visible and, more importantly, not susceptible to becoming tangled together or snagged by the surroundings. Consequently, e-textiles can be worn in everyday situations where currently available wearable computers would hinder the user. E-textiles also have greater flexibility in adapting to changes in the computational and sensing requirements of an application for the purpose of managing power consumption and context awareness. The number and location of sensor and processing elements can be dynamically tailored to the current needs of the user and application, rather than being fixed at design time.
