Abstract Tactile sensing in high‐temperature environments remains a critical challenge for robotic systems operating in industrial manufacturing, food processing, and other high‐temperature assembly operations. Herein, we report a heat‐resistant flexible tactile sensor with comprehensive high performance, featuring a hierarchical architecture comprising polyimide foam/carbon fiber composite as the sensing layer, flexible graphite paper electrodes, and fiberglass‐reinforced silicone rubber encapsulation. The sensor exhibits ultra‐high sensitivity (414.86 kPa −1 in the range of 1–500 kPa), wide detection range (0.0023– 1200 kPa), rapid response/recovery times (30 and 7 ms), and outstanding cyclic stability (12 000 cycles at 200 kPa). Remarkably, the sensor maintains stable operation at continuous temperatures up to 320°C and survives direct flame exposure at 727°C for 30 s. Integrated into a five‐fingered robotic hand, the sensor achieves intelligent high‐temperature object recognition of heated cookies at 150°C with 100% classification accuracy using 1D‐CNN. Furthermore, implementation in a two‐finger robotic arm demonstrates precise gravimetric sensing and droplet‐level mass detection capabilities (30–50 mg) for safe handling of high‐temperature liquids. This work demonstrates heat‐resistant flexible tactile sensors with comprehensive high‐performance characteristics, enabling reliable intelligent sensing and safe operation in extreme thermal environments previously inaccessible to flexible electronics.
