Abstract Formaldehyde (HCHO), as a common volatile organic compound, has serious impact on human health in the daily lives and industrial production scenarios. Given security issue of HCHO detection danger warning, ZIF‐8/copper foam based pulsed airstream‐driven triboelectric nanogenerator (ZCP‐TENG) is designed to develop self‐powered sensors. By combining contact electrification electrostatic induction, ZCP‐TENG can be utilized for airflow energy harvesting concentration detection. The short‐circuit current output power reach 2.0 µA 81 µW (20 ppm). With high surface area, abundant micro‐nano pores, excellent permeation flux, ZCP‐TENGs exhibit sensing response (61.3% at 100 ppm), low limit (≈2 rapid response/recovery time (14/15 s), which served highly sensitive selective sensor. connecting an intelligent wireless alarm, are construct warning system monitor remind exceedance situations. Moreover, by support vector machine model, difference concentrations quickly identified with average prediction accuracy 100%. This study illustrates that have broad application prospects provide guidance monitoring warnings.

Abstract Wearing face masks is an effective non‐pharmaceutical strategy to inhibit the transmission of airborne diseases. Nonetheless, most commercial lack disinfecting capabilities, posing risks secondary transmission, while those with antimicrobial coatings are incapable instant pathogen inactivation. Herein, a proof‐of‐concept mask demonstrated consisting Cu(OH) 2 ‐nanowire electroporation filter powered by respiration‐driven triboelectric nanogenerator (R‐TENG). The R‐TENG comprises electrospun polyvinyl alcohol (PVA) and polyvinylidene fluoride (PVDF) membranes. A dome‐shaped PVA membrane specifically designed maximize contact area. Coupling novel dome‐shape design maximized β‐phase crystallites PVDF, enhanced generates open‐circuit voltage 120 V under normal breathing rate adult, resulting in amplified electric field 19 MV m −1 at nanowire tips filter. Under this high localized field, inactivation bacteria (>99.9%) achieved via synergy physical penetration. Conversely, when disconnected, only partial (90%–99%) penetration realized. For first time, it shows that viable solution achieve instant, disinfection, paving way for next‐generation masks.

Designing friction materials with high electron storage capacity, work function, low cost, and stability is an important method to improve the output performance of a triboelectric nanogenerator (TENG). Here, we report two kinds based on Keggin-type polyoxometalates (POMs)-modified graphite carbon nitride (g-C3N4), namely, g-C3N4@PMo12 g-C3N4@PW12, form TENG commercial indium tin oxide/poly(ethylene terephthalate) (ITO/PET) electrodes. The test shows that device exhibits voltage about 78 V, current 657 nA, transfer charge 15 nC, which more than 3 times higher unmodified TENG. This improvement attributed fact POM loaded surface g-C3N4 can be used as shallow trap increase capacity through interaction density material by increasing function composite. not only broadens choices but also offers practical means enhancing TENG's performance.
