Structurally stretchable CNT-TFT backplane enabled by honeycomb mesh structure. a Photograph of the CNT-TFT backplane conformally covering a baseball. Inset shows the micrograph of one transistor. b Transfer characteristics measured at various tensile strains up to 10 %. c, d Mechanical simulation of hexagonal mesh structures with side lengths of 1.25 (c) and 1.85 mm (d) when stretched by 2 mm in horizontal direction. The white dashed circles mark the locations of active devices. Reproduced from ref. [68]
