Project description
Flexible near-infrared photodetectors for wearable healthcare devices
Wearable healthcare devices use high-performance near-infrared (NIR) photodetectors to gather real-time data and offer personalised medical diagnostics. These monitors can measure vital signs and physiological parameters like blood oxygenation, heart rate, and pulse rate. Although there has been progress in developing rigid self-powered NIR photodetectors, the exploration of flexible self-powered NIR photodetectors and their integration into wearable devices remains necessary. The MSCA-funded SPINIP project aims to address this gap by developing flexible and efficient NIR photodetectors capable of operating in self-powered mode and seamlessly integrating into wearable healthcare devices. The project will use eco-friendly tin-based perovskite-inspired materials (PIMs) with the ability to detect light across the UV-visible-NIR regions and maintain good air stability.
Objective
Wearable healthcare devices have disrupted health monitoring with personalized medical diagnostics and real-time data collection. An essential component of such devices are high-performance near-infrared (NIR) photodetectors, which facilitate the non-invasive measurement of vital signs and physiological parameters such as blood oxygenation, heart rate, and pulse rate. Significant progress has been made in exploring functional materials for self-powered NIR photodetectors on rigid substrates. However, the development of flexible self-powered NIR photodetectors and their integration into wearable device applications are largely overlooked in the literature. In SPINIP, we aim to develop efficient and stable flexible NIR photodetectors operating in self-powered mode (or zero bias) based on non-toxic and cost-effective semiconductors tailored for seamless integration into wearable healthcare devices. In particular, we will leverage eco-friendly tin-based perovskite-inspired materials (PIMs), starting from A2SnI6, owing to their broadband photodetection from UV-visible-NIR regions, good air stability, and low-temperature solution processing. The mechanical flexibility of photodetectors is a paramount feature, enabling seamless adherence to various surfaces and conforming to the dynamic movements of the human body. The mechanical flexibility of the device will be investigated via in-situ nanoindentation in FE-SEM. To ensure flexibility, we will perform thorough composition engineering of photoactive PIMs films and explore the synergetic effects of polymer scaffolds and hybrid annealing. The performance of NIR photodetectors will be enhanced by understanding the defect chemistry of PIMs, the charge transport within the device components, and the device physics. The reliability of the photodetectors will be verified in different conditions (environmental, thermal, and mechanical) and will be improved by reducing the ion migration and device engineering approaches.
