Caption

This is a demonstration of a stretchable crumpled graphene photodetector. The movie demonstrates stretchability under cyclic uniaxial tensile strains reaching a maximum strain of 200 percent, together with dynamic photoresponse of the device to cyclic on-and-off illumination of 405 nm-wavelength light at 0 percent (blue curve) and 200 percent (red curve) strains.
