Abstract Multimodal force identification by electronic skin (E‐skin) provides comprehensive and precise tactile information that can enhance elaborated functions of fine discrimination, robotic manipulation, gesture recognition. However, it remains a great challenge to realize such complicated from highly simplified E‐skin sensing system. Here, mimicking the multi‐mechanoreceptor synergistic effect in human skin, simple, thin, soft, intelligent sensor composed an asymmetrically arrangement strain units array for multimodal decoding is reported. The type exhibits good performance with excellent sensitivity shear (2.5 N –1 ), vertical (0.11 kPa enables 3D refactoring, as well accurate recognition sliding direction tracking. Another unique feature side screen effect, allows yield accuracy gauge factor 1492 measuring. Furthermore, integration sensors into offers capability capturing dynamic real‐time stress distribution on hand various conditions. This work new route complex force‐sensing simple structure shows potential robotics, human‐machine interface, virtual reality/augmented reality (VR/AR).
