ABSTRACT The development of bio‐inspired electronic skin equipped with a functionally integrated perception‐processing‐response mechanism is critical for achieving natural interaction in humanoid robots. While organic electrochemical transistors show great promise in biosensing and neuromorphic computing due to their unique ion‐electron coupling, existing studies have largely focused on optimizing single functional units. Achieving system‐level synergy remains a challenge; traditional monolithic integration is hindered by material and electrolyte incompatibilities, which inevitably leads to performance trade‐offs among multimodal sensing, synaptic simulation, and logic operations. Furthermore, the resulting fixed hardware architectures lack the adaptability required for complex robotic tasks. Here, we present a function‐oriented modular integration strategy utilizing ultra‐thin SEBS elastomers to build a reconfigurable “artificial peripheral nervous system.” Taking advantage of the native self‐adhesiveness and exceptional flexibility of SEBS, we enable the Lego‐like assembly and interconnection of independently optimized modules, including high‐sensitivity ion (K + and Na + ) and temperature sensors, artificial synapses, and logic gates. This approach not only decouples the fabrication processes to preserve the performance of each device but also facilitates on‐demand system reconfiguration. Thereby, we demonstrate a unified platform capable of multimodal signal acquisition, brain‐like computing, and preliminary decision‐making, offering a novel hardware solution for future intelligent and customizable human‐machine interfaces.
