Mechanical properties of the nanomesh electrodes. a–c Photographs of nanomesh electrode on flexible PET substrate. The current through the nanomesh switches on the LED a before strain, b with Ɛ = 1.2% and c with Ɛ = 2.5%. d Increase of sheet resistance versus bending radius for bendable transparent electrodes consisting of gold nanomesh networks, for 5 nm Au-Cu film with 17 at.% of Au on PET substrate. e Variation in resistance of the gold nanomesh electrode and Au-Cu film on PET film as a function of the number of cycles of repeated bending to a radius of 6 mm. f Typical SEM images of nanomesh after 10,000 bending cycles. The SEM images are representative of nanomesh bend after 10,000 cycles. White scale bar: 5 μm
