Ni‐CAT‐1‐on‐SLG construct on transparent flexible substrates for personal electronics. A) Photograph of CAT‐1‐on‐SLG‐25 nm construct on attaching to the skin of a human hand using PDMS as the substrate. B) Photograph of Ni‐CAT‐1‐on‐SLG‐25 nm construct on PET substrate at bending state with a bending radius of 3 mm. The construct was connected to a circuit to light up a LED, where the resistance stability of this construct was demonstrated at the bending state. C) Photograph of Ni‐CAT‐1‐on‐SLG‐25 nm construct on PET substrate in large size, 3 cm × 5 cm, revealing the excellent transparency of this MOF‐on‐SLG construct. Blue square in the inner circle marks the area of Ni‐CAT‐1‐on‐SLG‐25 nm construct, while the out circle marks the edge of PET. D) Illustration of the flexible device composed of Ni‐CAT‐1‐on‐SLG construct. E) In situ resistance variation of the transparent and flexible device alone 205 bending cycles. F) Electrical response to NH₃ using this device based on the Ni‐CAT‐1‐on‐SLG‐25 nm construct on PET substrate at both flat and bending state.
