Flexible sensor detects near-infrared light with higher response after repeated bending

A research team has developed a flexible near-infrared (NIR) photodetector that delivers photoresponsivity more than five times higher while maintaining its performance under repeated bending. The technology is expected to serve as a core platform for next-generation flexible optoelectronic devices, including wearable health care devices, medical diagnostic sensors and optical communication receivers.
