The current $16B flexible electronics market is growing at an annual rate of 14.5% and is predicted to reach $67B in 2024. Research and development activities related to this technology have been a focus of work conducted at the University Of Waterloo (UW) over the past decade, during which time researchers have made significant contributions to the field. This program will further expand these efforts to create opportunities to lead this rapidly emerging technology cluster and enable the next generation of flexible nanotechnology for a wide range of applications in large-area electronics.***The goals of this program are to develop and combine novel and conventional processing techniques with nano-materials to create functionally enhanced devices for flexible electronics. The program will investigate the use of three-dimensional (3-D) nanowires in tandem with two-dimensional (2-D) electronic materials to develop nanoelectronics that will take advantage of mechanical bending to enhance the functionality of the electronic system. ***In one focus, the integration of nanowires onto plastic will take advantage of the movement of nanowires protruding from the surface during mechanical bending. As the nanowires move closer together the optical absorption of light within the nanowires is enhanced. This effect can be exploited in nanowire-based solar cells and sensors for enhancing cell efficiency or creating optical sensors with high sensitivity. A second study will explore the effect of bending on low-dimensional transition metal dichalcogenides to create high-performance electronics that are also mechanically forgiving. ***The combination of the 3-D sensors and 2-D electronics will lead to functionally enhanced sensor systems. The program will demonstrate an integrated technology for conformal sensor arrays. Existing imaging technology, such as digital cameras, have a series of optics in front of a flat sensor to minimize distortion of the captured image. A flexible array can conform to a more functional shape, such as the form of an eye, allowing low distortion and higher sensitivity using simple optics.***The program will impact the solar energy, flat-panel display, and medical imaging industry, and will have a long-term influence on emerging applications for high-performance, mechanically robust, and energy-efficient portable electronic devices. Each of the research components can also be used for a variety of applications, permitting easy dissemination of technology to industry. The range of technical areas to which students will be exposed will provide them with in-depth training in the field of nanotechnology; this training will allow them to conduct future research activities to impact the field as a whole, and to provide to them a fundamental understanding of how this technology will influence and impact emerging commercial applications. **

目前160亿美元的柔性电子市场正以每年14.5%的速度增长，预计到2024年将达到670亿美元。在过去的十年中，与该技术相关的研究和开发活动一直是滑铁卢大学（UW）开展的工作的重点，在此期间，研究人员对该领域做出了重大贡献。该项目将进一步扩大这些努力，创造机会，引领这一迅速崛起的技术集群，并使下一代柔性纳米技术在大面积电子领域的广泛应用成为可能。该计划的目标是开发和结合新颖和传统的加工技术与纳米材料，以创造功能增强的柔性电子设备。该项目将研究三维（3-D）纳米线与二维（2-D）电子材料的结合使用，以开发纳米电子学，利用机械弯曲来增强电子系统的功能。其中一个重点是，将纳米线集成到塑料上将利用纳米线在机械弯曲过程中从表面伸出的运动。当纳米线靠近时，纳米线内的光吸收增强。这种效应可以用于纳米线太阳能电池和传感器，以提高电池效率或制造高灵敏度的光学传感器。第二项研究将探索弯曲对低维过渡金属二硫族化合物的影响，以创造高性能的电子产品，同时也具有机械宽恕性。3-D传感器和2-D电子设备的结合将导致功能增强的传感器系统。该项目将演示保形传感器阵列的集成技术。现有的成像技术，如数码相机，在平面传感器前面有一系列光学元件，以尽量减少捕获图像的失真。灵活的阵列可以适应更多功能的形状，比如眼睛的形状，使用简单的光学元件就可以实现低畸变和高灵敏度。***该项目将影响太阳能、平板显示器和医疗成像行业，并将对高性能、机械坚固、节能的便携式电子设备的新兴应用产生长期影响。每一个研究组成部分也可用于各种应用，使技术易于向工业传播。学生将接触到的一系列技术领域将为他们提供纳米技术领域的深入培训；这种培训将使他们能够开展未来的研究活动，以影响整个领域，并使他们对这项技术将如何影响和影响新兴的商业应用有一个基本的了解。**
