Curvature sensing plays an important role in structural health monitoring,damage detection,real-time shape control,modi-fication,etc.Developing curvature sensors with large measurement ranges,high sensitivity,and linearity remains a major chal-lenge.In this study,a curvature sensor based on flexible one-dimensional photonic crystal[1D-PC]films was proposed.The flexible 1D-PC films composed of dense chalcogenide glass and water-soluble polymer materials were fabricated by solution processing.The flexible 1D-PC film curvature sensor has a wide measurement range of 33-133 m-1 and a maximum sensitivity of 0.26 nm/m-1.The shift of the transmission peak varies approximately linearly with the curvature in the entire measurement range.This kind of 1D-PC film curvature sensor provides a new idea for curvature sensing and measurement.
