Flexible Quantum Dot Photosensor for Visible–Infrared Spectrum

Team: Hyung Min Ko

Collecting meaningful information from the body is essential in human-oriented technologies, such as bioimage sensors, soft robotics, and healthcare monitoring. Quantum dots, tiny semiconducting particles in a few nanometers, have unique optoelectronic properties such as bandgap tunability and high light absorption. Our group aims to develop a thin-film photosensor device based on quantum dots with enhanced sensitivity and response time. Specifically, we utilize non-toxic quantum dot materials for biocompatible applications in collaboration with Prof. Sungjee Kim at Chemistry Department, POSTECH.
