Biodegradable and renewable poly(lactic acid) (PLA) fibrous membranes have emerged as a promising approach to replace traditional polymeric air filters, but are still challenged by relatively low electroactivity poor electret properties. Herein, we disclose an effective electrospinning strategy substantially promote the extreme orientation of stereocomplexed PLA (OSC-PLA), conferring significant alignment refinement electrospun nanofibers (diameter ∼370 nm), well facilitate formation electroactive phases (i.e., β-phase, phase, stereocomplex crystals). Benefiting from well-tailored morphology remarkable electroactivity, OSC-PLA nanofibrous (NFMs) were characterized largely improved dielectric properties, surface potential (over 3.64 kV), PM0.3 filtration properties (93.33% at 85 L/min) compared pure PLLA membrane (2.01 kV 80.21%). It enabled assembly triboelectric nanogenerator (TENG) filters using NFMs active layer, yielding excellent charge regeneration mechanisms output current nearly 80 nA, driven respiratory vibrations L/min, thus permitting high humidity resistance, exemplified removal efficiency 95.02% RH 90%. Moreover, deep machine learning man–machine interaction integrated with OSC-PLA-based TENGs, demonstrating long-term monitoring high-precision diagnosis (accuracy 96.88%) various patterns. The proposed ecofriendly ultrafine highly appealing for sustained healthcare self-powered intelligent diagnosis.

Abstract Air pollution is a silent killer. It poses significant health threat, affecting over 80% of the global population and leading to respiratory cardiovascular diseases. Electrospun nanofiber filtration membranes have made tremendous progress due their large surface areas, adaptable structures, self‐polarizing properties. This review explores recent developments in across four key areas: principles, material design, structural innovations, functionalities. Initially, classical mechanisms discussed, followed by an overview sustainable materials green technologies for advanced filtration. then delve into advancements, highlighting nanofibers with high roughness, ultra‐fine diameters, bimodal distributions. Inspired nature, these innovations led creation high‐performance membranes. Current research focuses on anti‐bacterial antiviral membranes, as well intelligent systems capable sensing physiological signals. Last, existing challenges membrane development, such new mechanisms, preparation technologies, reusable highlighted. anticipated that solutions problems will open up possibilities functional biodegradable smart wearables, upscale healthcare.
