项目摘要

Wearable technologies such as smart watches, smart glasses or even smart pacemakers have caused a paradigm shift in consumer electronics with huge potential in areas such as healthcare, fashion and entertainment (e.g. augmented reality glasses). Currently these devices are still powered by batteries needing frequent replacement or recharging, a key challenge holding back wearable electronics. Thermoelectric generators (TEGs) are an attractive alternative to batteries as they can generate up to several 100 microwatts power from heat (e.g. radiated from the human body), are safe and long-lasting with zero emissions. Current TEGs however are plagued by low efficiencies, high manufacturing costs, and are fabricated onto rigid substrates which makes it difficult to integrate them into many applications that require conformal installation. There is therefore considerable interest in the fabrication of flexible TEGs that can harvest energy from body heat for wearable applications and other heat sources. This project seeks to develop a new generation of thermoelectric (TE) hybrid materials for flexible TE energy harvesting applications by combining inorganic materials with controlled 3D nanostructures and organic conducting polymers (OCPs). The materials have not been realized to date and will be optimized to yield enhanced TE power factors (PFs).

智能手表、智能眼镜甚至智能起搏器等可穿戴技术已经导致了消费电子产品的范式转变，在医疗、时尚和娱乐等领域具有巨大的潜力(例如增强现实眼镜)。目前，这些设备仍然由电池供电，需要频繁更换或充电，这是阻碍可穿戴电子产品的一个关键挑战。热电发电机(TEG)是电池的一种有吸引力的替代品，因为它们可以从热量(例如来自人体的辐射)中产生高达100微瓦的电力，并且安全且持久，零排放。然而，目前的TEG存在效率低、制造成本高的问题，而且是在刚性基板上制造的，这使得它们很难集成到许多需要保形安装的应用中。因此，人们对制造可从可穿戴应用和其他热源的人体热能中获取能量的柔性热垫有相当大的兴趣。该项目旨在通过将具有可控3D纳米结构的无机材料与有机导电聚合物(OCP)相结合，开发用于柔性热电(TE)能量收集的新一代热电(TE)杂化材料。到目前为止，这些材料还没有实现，将进行优化，以产生增强的TE功率因数(PFS)。
