Advanced Solid Energy Solutions for Wearable Electronics

从智能手表和耳机到医疗传感/监测贴片，再到智能服装和电子纺织品，可穿戴电子产品涵盖了各种各样的产品，在我们的生活中无处不在，为我们提供了前所未有的便利，有时甚至是挽救生命的帮助。虽然可穿戴电子产品已经从小众技术发展成为主流必需品，但它们仍然需要用新的材料和外形因素来摆脱传统电子产品，使其真正便携和可穿戴。一个需要大力努力的领域是能源，不仅是在电力供应方面，而且在电力消耗方面。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组件。目前这种能量解决方案的障碍是：a)缺乏高能量密度和高功率密度的电极材料；B)缺乏高性能、无腐蚀性、良性和环保的固体电解质，以尽量减少包装重量和体积，并实现灵活和可穿戴的外形因素；c)晶体管中缺乏介电材料来降低驱动电压。解决方案还应表现出长期的稳定性，并能够在加拿大的极端天气条件下生存。拟议的研究将通过开发固态电化学能量存储（SEES）系统和印刷有机场效应晶体管（OFET）的栅极介电体的关键材料构建块，实现所需的能量解决方案。see设备以固态形式存储和传输能量，为下一代消费和汽车电子产品提供安全、清洁和有效的动力。电解门控有机场效应晶体管（egfet）由于其可印刷性、灵活性和大规模制造潜力，已成为可穿戴生物电子和物联网设备的重要组成部分。拟议的研究将有助于解决可穿戴消费电子产品的紧迫能源存储需求，这些电子产品适合在加拿大北部气候等恶劣环境条件下部署。利用在以前的资助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，以提供高能量和功率密度并且安全操作的薄，灵活和轻质see设备。我们将对先前工作中的聚合物电解质进行调整，并将其应用于egfet，将工作电压降低到1V以下，以确保低功耗工作。结合这些创新将带来轻薄、灵活和轻便的设备，这些设备是快速发展的可穿戴电子产品的关键推动者。

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.
