Non-invasive medical nanofiber technology, characterized by its high specific surface area, biocompatibility, and porosity, holds significant potential in various domains, including tissue repair biosensing. It is increasingly becoming central to healthcare offering safer more efficient treatment options for contemporary medicine. Numerous studies have explored non-invasive nanofibers recent years, yet a comprehensive overview of the field remains lacking. In this paper, we provide summary applications electrospun fields, considering multiple aspects perspectives. Initially, introduce electrospinning nanofibers. Subsequently, detail their health, health monitoring, personal protection, thermal regulation, wound care, highlighting critical role improving human health. Lastly, paper discusses current challenges associated with offers insights into future development trajectories.

Abstract Waterproof and breathable nanofiber membranes are highly desirable for protective textiles; however, the practical application of is limited by fluorine‐containing material addition or complicated post‐treatment. Herein, we reported unique fluorine‐free polyurethane (PU)/poly(styrene‐ b ‐s‐ ‐styrene) (SBS) a facile direct electrospinning. Owing to SBS, hydrophobicity, waterproofness, mechanical properties PU were dramatically enhanced. Furthermore, interconnective channels constructed after introduction SBS into membrane, which resulted in enhanced breathability. The enhancement comprehensive performance PU/SBS composite membrane might be attributed π–π interactions between PU. By adjusting concentration PU/SBS, optimized systematically, exhibiting satisfactory waterproofness (hydrostatic pressure, 47.4 kPa), acceptable breathability (water vapor transition rate, 5.6 kg m −2 d −1 ), outstanding (breaking strength, 5.7 MPa; breaking elongation, 387.9%). PU/SBS‐14 ideal wearable textiles, especially outdoor clothing, wound dressings, medical gowns.
