a Current–voltage relationship of Cu mesh/PVA film (45 mm × 45 mm) in its flat and bent state with a bending radius of 5 mm. b Changes in the sheet resistance of the Cu mesh/PVA film and ITO/PVA films as a function of the bending radius. The inset shows an optical microscope image of the ITO film after the bending test. c Changes in the sheet resistance of the Cu mesh/PVA film with ~ 50 µm thick PVA substrate with respect to the bending cycles at a fixed bending radius of 4 mm
