Abstract Expanding wearable technologies to artificial tactile perception will be of significance for intelligent human–machine interface, as neuromorphic sensing devices are promising candidates due their low energy consumption and highly effective operating properties. Skin‐compatible conformable features required the purpose realizing perception. Here, we report an intrinsically stretchable, skin‐integrated system with triboelectric nanogenerators organic electrochemical transistors information processing. The integrated provides desired sensing, synaptic, mechanical characteristics, such sensitive response (~0.04 kPa −1 ) low‐pressure, short‐ long‐term synaptic plasticity, great switching endurance (>10 000 pulses), symmetric weight update, together high stretchability 100% strain. With neural encoding, demonstrations capable recognizing, extracting, encoding information. This work a feasible approach wearable, skin‐conformable application prospects in robotics replacement prosthetics.
