The fibrous thermoplastic polyurethane (TPU) scaffold endows the SPRABE‐skin tissue‐like softness (Young's modulus 3.36 MPa) stretchability, good permeability water vapor, self‐protection against adverse loading events. A strain layer composed MXene‐carbon nanotubes@TPU (MXene‐CNT@TPU) composition exhibits ultra‐high sensitivity wide range (gauge factor at 485% reaches 63 494). An electrode made MXene‐waterborne (MXene‐WPU) provides adhesive electrode‐skin interface, which enables biopotentials, such as electrocardiograph (ECG), electromyograph (EMG), electroencephalo‐graph (EEG), improved fidelity even under various dynamic interferences.
