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.

Abstract Flexible electromechanical sensors frequently suffer from unexpected impact loadings caused by slipping, collisions and falling objects, to name a few. Without sufficient protection, these undesired impacts would lead critical mechanical instability even damage flexible sensors, resulting in restricted measurement range imprecise sensing.
