项目摘要

Material degradation is a primary concern to every material scientist and engineer, not only does degradation lead to failure, but results in the need for repair - a very costly endeavour. In this perspective, it is of interest to develop self-healing materials that will make maintenance redundant. As opposed to inorganic semiconductors, organic semiconducting materials are soft, which makes them ideal to be used in flexible and stretchable electronic devices, which can be directly applied to the human skin. Wearable electronics, however, are particularly prone to mechanical damage and fatigue, which is why it is paramount to develop more robust materials, like self-healable semiconductors.This fellowship will, for the first time, make it possible to synthesise intrinsic self-healing organic semiconductors and incorporate them into fully flexible, stretchable and wearable electronic devices, respectively bionic skin, to measure biological metabolites associated with diabetes (glucose), fatigue (lactate) and stress (cortisol). The electric charges will be transported via the conjugated polymer backbone, while additional supramolecular functionalities (i.e. non-binding interactions) will be incorporated into the chemical structure to ensure self-healing via the formation of dynamic bonds. The study of the new self-healing polymers will then be extended to other dynamically bonding functional groups to evaluate which chemistry is best suited for organic semiconductors. Subsequent steps will focus on the self-healing dynamics and rates, and the incorporation of the new materials into flexible electronic prototype devices.The realisation of healable organic semiconductors, for the first time, will allow the fabrication of lightweight, -wearable sensors directly applied to the human skin. This will make it possible to continuously monitor medically relevant body functions and present a significant step forward in the development of affordable biological sensors and continuous patient monitoring, ultimately enhancing medical diagnostics and opening-up new treatment possibilities.

材料退化是每位物质科学家和工程师的主要问题，不仅降解会导致失败，而且导致需要维修 - 这是一项非常昂贵的努力。从这个角度来看，开发自我修复的材料将使维护多余的材料很有趣。与无机半导体相反，有机半导体材料柔软，这使得它们适用于柔性和可拉伸的电子设备，可以直接应用于人类皮肤。 Wearable electronics, however, are particularly prone to mechanical damage and fatigue, which is why it is paramount to develop more robust materials, like self-healable semiconductors.This fellowship will, for the first time, make it possible to synthesise intrinsic self-healing organic semiconductors and incorporate them into fully flexible, stretchable and wearable electronic devices, respectively bionic skin, to measure biological metabolites associated with糖尿病（葡萄糖），疲劳（乳酸）和胁迫（皮质醇）。电荷将通过共轭聚合物主链运输，而其他超分子功能（即非结合相互作用）将纳入化学结构中，以确保通过动态键的形成自我修复。然后，对新的自我修复聚合物的研究将扩展到其他动态粘结官能团，以评估哪种化学最适合有机半导体。随后的步骤将集中在自我修复动力学和速率上，并将新材料掺入柔性电子原型设备中。可治愈的有机半导体的实现将首次允许制造轻质，可磨损的传感器，直接施加到人类皮肤上。这将使连续监测医学相关的身体功能并在开发负担得起的生物传感器和连续的患者监测方面迈出了重要一步，最终增强了医学诊断并开放新的治疗可能性是可能的。
