Abstract The skin‐like temperature–pressure sensing capabilities are fundamental features for the next‐generation artificial intelligence applications, such as human–machine interactions and soft robotics. previous studies on devices have focused single‐point pressure or temperature sensing, whereas detecting distributions of simultaneously still remain challenging. In this article, a flexible dual‐parameter sensor array based amorphous indium gallium zinc oxide (a‐IGZO) thin film transistors (TFTs) is proposed. proposed array, decoupling perceptions realized by optimizing combination MXene carbon nanotubes in form hybrid films difference coefficient. amplification signal scale achieved using a‐IGZO TFT‐based cross‐active matrix addressing design. After being amplified TFTs, sensors exhibit satisfactory sensitivity. Further, 7 × 4 6 alternately integrated 5 cm area, thus achieving spatial distribution mapping signals without interference. design has potential application field multifunctional electronic skin.
