Wearable electronics, covering a very diverse range of products from smartwatches and headsets to medical sensing/monitoring patches to smart clothing and e-textiles, have become pervasive in our lives, providing us unprecedented convenience and at times even life-saving assistance. While wearable electronics have evolved from niche technologies to main stream necessities, they still need to break away from traditional electronics with new materials and form factors to make them truly portable and wearable. An area needing significant effort is energy, not only with respect to power supply but also regarding power consumptions. Advanced energy solutions require high performing and clean power sources as well as low-power driving circuits and components. The current obstacles to such energy solutions are: a) a lack of high energy density and high power density electrode materials; b) a lack of high performance, non-corrosive, benign, and environmental friendly solid electrolytes to minimize the packaging weight and volume and to enable flexible and wearable form factors; and c) a lack of a dielectric material in transistors to reduce driving voltage. Solutions should also exhibit long term stability and be able to survive the extreme Canadian weather conditions. The proposed research will enable required energy solutions by developing critical material building blocks for solid-state electrochemical energy storage (SEES) systems and for the gate dielectrics of printed organic field-effect transistors (OFET). A SEES device stores and delivers energy in the solid-state, providing safe, clean, and effective means to power next generation consumer and automotive electronics. Electrolyte-gated organic field effect transistors (EGFETs) have emerged as important building blocks for wearable bioelectronics and IoT devices due to their printability, flexibility, and potential for large-scale manufacturing. The proposed research will contribute to resolving pressing energy storage needs for wearable consumer electronics suitable to be deployed under severe environmental conditions such as in Northern Canadian climates. Leveraging the material building blocks successfully developed under previous grants, the scope of the proposed Discovery Grant is to further innovate on those novel material systems through sustainable and low-cost approaches for thin, flexible and light-weight SEES devices that provide high energy and power density and are safe to operate. We will tune polymer electrolytes from previous work and apply them to EGFETs to reduce operation voltage to sub 1V to ensure low power operation. Combining these innovations will lead to thin, flexible and lightweight devices that are critical enablers for the rapidly evolving wearable electronics.

可穿戴电子产品涵盖了从智能手表和耳机到医疗传感/监测贴片到智能服装和电子纺织品的各种产品，已经在我们的生活中无处不在，为我们提供了前所未有的便利，有时甚至是救命的帮助。虽然可穿戴电子产品已经从利基技术发展成为主流必需品，但它们仍然需要用新材料和形状因素摆脱传统电子产品，使其真正便携和可穿戴。需要做出重大努力的一个领域是能源，不仅是关于电力供应，而且关于电力消耗。先进的能源解决方案需要高性能和清洁的电源以及低功耗驱动电路和元件。这种能量解决方案的当前障碍是：a）缺乏高能量密度和高功率密度电极材料; B）缺乏高性能、无腐蚀性、良性和环境友好的固体电解质，以最小化封装重量和体积并实现柔性和可穿戴的形状因子;以及c）缺乏晶体管中的介电材料以降低驱动电压。解决方案还应具有长期稳定性，并能够在加拿大极端天气条件下生存。拟议的研究将通过开发用于固态电化学能量存储（SEES）系统和印刷有机场效应晶体管（OFET）的栅极封装的关键材料构建模块来实现所需的能源解决方案。SEES器件以固态形式存储和输送能量，为下一代消费电子和汽车电子产品提供安全、清洁和有效的供电方式。电解质栅极有机场效应晶体管（EGFET）由于其可印刷性、灵活性和大规模制造的潜力，已成为可穿戴生物电子和物联网设备的重要构建模块。拟议的研究将有助于解决可穿戴消费电子产品的紧迫储能需求，这些电子产品适合在加拿大北方气候等恶劣环境条件下部署。利用在以前的赠款下成功开发的材料构建模块，拟议的发现资助的范围是通过可持续和低成本的方法进一步创新这些新型材料系统，用于薄，灵活和轻质的SEES设备，提供高能量和功率密度，并且操作安全。我们将从以前的工作中调整聚合物电解质，并将其应用于EGFET，以将工作电压降低到低于1V，以确保低功耗运行。结合这些创新将导致薄，灵活和轻便的设备，是快速发展的可穿戴电子产品的关键推动因素。
