Abstract Large-area metamorphic stretchable sensor networks are desirable in haptic sensing and next-generation electronics. Triboelectric nanogenerator-based self-powered tactile sensors single-electrode mode constitute one of the best solutions with ideal attributes. However, their large-area multiplexing utilizations restricted by severe misrecognition between nodes high-density internal circuits. Here, we provide an electrical signal shielding strategy delivering a untethered triboelectric electronic skin (UTE-skin) ultralow rate (0.20%). An omnidirectionally carbon black-Ecoflex composite-based layer is developed to effectively attenuate electrostatic interference from wirings, guaranteeing low-level noise matrices. UTE-skin operates reliably under 100% uniaxial, biaxial, 400% isotropic strains, achieving high-quality pressure imaging multi-touch real-time visualization. Smart gloves for recognition, intelligent insoles gait analysis, deformable human-machine interfaces demonstrated. This work signifies substantial breakthrough sensing, offering previously challenging issue arrays.
