Wearable technologies such as smart glasses have recently caused much excitement in the business and technology spheres. However, these examples use relatively conventional technologies. The real breakthrough in wearable technologies will come when we can manufacture materials and components that are flexible and non-intrusive enough to be integrated into everyday items, such as our clothes. The main challenges to achieving this are the lack of reliability, performance limitations of (opto)electronics on flexible substrates, and the lack of flexible power sources. Much of the necessary device technology exists in some nascent form; our proposal will provide the technological innovation to allow its manufacture in a form compatible with wearable technology. In this project we aim to solve a key technological challenge in wearable technologies, namely that of scalable and cost-effective manufacturing by taking advantage of the following areas of UK technological excellence in components and scale-up technologies:1) The assembled consortium has an emphasis on inventing and demonstrating the key wearables technologies required on flexible substrates for displays, energy harvesting and sensing. 2) The consortium consists of key researchers in the fields of modeling prediction, metrology, systems integration and design for reliability, all required to complement the device engineering.3) Importantly, by integrating, right from the word go, the aspect of Roll-to-Roll (R2R) scale-up of manufacturing such flexible technologies, we will create the manufacturing know-how to allow fundamental science to translate into manufacturing.The deposition processes for all wearables face similar challenges such as low material yield, high waste (important for functional films where minimizing waste saves costs substantially) and lack of in-situ process monitoring. Additionally, for our targeted applications, there is currently no scalable cost-effective manufacturing technology. Roll-to-roll processing fulfills this crucial need and our aim will be to enable this scalable manufacturing technology for inexpensive production on flexible substrates, an area very much underexplored in terms of advanced functional materials, but one with huge potential.

智能眼镜等可穿戴技术最近在商业和技术领域引起了很大的兴奋。然而，这些示例使用相对传统的技术。可穿戴技术的真实的突破将在我们能够制造出足够灵活和非侵入性的材料和组件时到来，这些材料和组件可以集成到日常用品中，比如我们的衣服。实现这一目标的主要挑战是缺乏可靠性、柔性基板上的（光）电子器件的性能限制以及缺乏柔性电源。许多必要的设备技术以某种新生形式存在;我们的提案将提供技术创新，使其以与可穿戴技术兼容的形式制造。在这个项目中，我们的目标是解决可穿戴技术中的一个关键技术挑战，即通过利用英国在组件和放大技术方面的以下领域的技术优势，实现可扩展和具有成本效益的制造：1）组合的财团重点是发明和展示用于显示，能量收集和传感的柔性基板上所需的关键可穿戴技术。2)该联盟由建模预测、计量学、系统集成和可靠性设计领域的关键研究人员组成，所有这些都是补充器件工程所需的。3）重要的是，通过从一开始就集成制造这种灵活技术的卷到卷（R2 R）放大方面，我们将创造制造技术，使基础科学转化为制造。所有可穿戴设备的沉积工艺都面临着类似的挑战，例如材料产量低，高浪费（对于功能性膜很重要，其中最小化浪费显著节省成本）和缺乏原位工艺监测。此外，对于我们的目标应用，目前还没有可扩展的具有成本效益的制造技术。卷对卷加工满足了这一关键需求，我们的目标是使这种可扩展的制造技术能够在柔性基板上进行廉价生产，这是一个在先进功能材料方面探索不足但潜力巨大的领域。
