In this study, Polyvinylidene fluoride (PVDF)/MXene composite nanofiber membranes containing different mass ratios of MXene powder were prepared via electrospinning technology and subsequently encapsulated with polyurethane to develop PVDF/MXene‐based electronic skin. The electronic skin exhibited remarkable mechanical strength, with a breaking stress of 1.04 ± 0.02 MPa and elongation at break of 96.73% ± 2.50% that were 2.04 and 1.25 times higher than those of pure PVDF nanofiber membranes, respectively. It also showed outstanding piezoelectric performance (output voltage 13.45 V, sensitivity 0.145 V/N). Furthermore, the electronic skin demonstrated excellent stability over 1000 periodic tests. Additionally, the PVDF/MXene‐based electronic skin has been successfully employed to monitor various human movements, such as finger, wrist, elbow, and foot movements, demonstrating its potential for applications in smart wearables, medical health monitoring, and human–computer interaction. 10.1002/app.70070 http://onlinelibrary.wiley.com/termsAndConditions#vor |
