Intrinsically stretchable CNT-TFTs. a Schematics of the fabrication process where CNT film is transferred to prestrained (50 %) PDMS substrate, forming buckled structure after the prestrain in PDMS is released. b In situ SEM images of the buckled CNT film obtained after prestretched to 25, 50, and 65 %. c, d Photographs of the TFTs before (c) and after (d) stretched to 30 %. e, f Stretching test showing the transfer characteristics (e), mobility, on-current, and off-current (f) of the CNT-TFTs at various tensile strains up to 57.2 %.
