Electronics or devices, which are flexible, wearable, rollable and/or foldable, will bring us completely different user experience and even change the way of our life. Making flexible and stretchable electronics and devices has become an important direction of advanced manufacturing. Recent advances in materials and manufacturing processes have enabled many new applications of flexible electronics/devices, for example, electronic paper, curved screens, foldable or rollable displays, flexible solar cells, tunable lens, artificial muscles, skin sensors and wearable biomedical devices for health monitoring. The market demand for flexible, printed, and organic electronics dramatically increases. Currently the global market is over $1B, and will grow up to $45B by 2016. Recently material or inkjet printing has emerged as a very promising technique for mass production of large-area flexible and stretchable electronics at relatively low cost. Inkjet printing is a versatile technique that places conductive inorganic or organic materials in a direct-writing manner to designated locations on elastomeric substrates. In spite of its many advantages, current inkjet printing technology still faces a number of technical challenges such as low conductivity of printed metallic circuits, weak adhesion between conductive materials and the substrate, low resolution compared to the conventional IC processes, and limited choices of conductive materials and substrate materials. In this project, we will develop new inkjet printing technologies that can overcome the abovementioned technical challenges and significantly improve performance of the printed electronics/devices. For example, the printed copper circuits by our technologies can achieve a breakthrough high conductivity up to 75% of bulk copper. Potentially our technologies can also achieve a breakthrough high resolution that allows for printing high-density integrated circuits. With many applications proposed to develop, this project will show significant benefit to Canada's economy and provide excellent training opportunities to Canada's young engineers.

柔性、可穿戴、可卷曲和/或可折叠的电子或设备将为我们带来完全不同的用户体验，甚至改变我们的生活方式。制造柔性、可拉伸的电子器件已成为先进制造的重要方向。材料和制造工艺的最新进展使柔性电子/设备的许多新应用成为可能，例如电子纸、曲面屏幕、可折叠或可卷曲显示器、柔性太阳能电池、可调镜头、人造肌肉、皮肤传感器和用于健康监测的可穿戴生物医学设备。市场对柔性、印刷和有机电子产品的需求急剧增加。目前全球市场规模超过 $1B，到 2016 年将增长到 $45B。 最近，材料或喷墨印刷已成为一种非常有前途的技术，可以以相对较低的成本大规模生产大面积柔性和可拉伸电子产品。喷墨印刷是一种多功能技术，可将导电无机或有机材料以直写方式放置到弹性体基材上的指定位置。尽管具有许多优点，当前的喷墨印刷技术仍然面临许多技术挑战，例如印刷金属电路的导电率低、导电材料与基板之间的附着力弱、与传统IC工艺相比分辨率较低、导电材料和基板材料的选择有限等。 在这个项目中，我们将开发新的喷墨印刷技术，可以克服上述技术挑战并显着提高印刷电子/设备的性能。例如，采用我们技术的印刷铜电路可以实现突破性的高导电率，高达块状铜的75%。我们的技术还可能实现突破性的高分辨率，从而可以打印高密度集成电路。该项目拟开发许多应用程序，将为加拿大经济带来显着效益，并为加拿大年轻工程师提供极好的培训机会。
