Preventing fracture in materials and devices integrated on largely bending film substrates has attracted much attention due to the rapid development of flexible electronics and soft robotics. We propose the surface-labeled grating method that is the fundamental and efficient technique for measuring surface bending strains with a single-nanoscale (<1.0 nm) in real time.
