ABSTRACT Advanced nanofibrous materials with excellent performance and functional integration is highly desired for developing emerging wearable electronics. In this work, carbon quantum dots/poly(vinylidene fluoride) (CDs/PVDF) based composite material proposed acts as a negative to boost output triboelectric nanogenerators (TENGs). The nanometer‐sized surface‐functionalized CDs acting nucleating inducers facilitate the polarized β ‐phase transition of PVDF polymer. more surface charge density CDs/PVDF membrane generated through PVDF, thereby leading larger electrostatic potential difference enhance transfer. Besides decreased beaded defects, uniform morphology fibers are yielded improve effective contact area. Moreover, nanofibers demonstrate unique multicolor fluorescence effect enabling promising applications in visualized displays sensing. Finally, fabricated TENG features short‐circuit current ~61.8 mA/m 2 maximum peak power ~11.7 W/m , exceeding that most state‐of‐the‐art nanofiber‐based reported date. As demonstration application potential, shows energy‐harvesting ability capacitors light up 125 green LEDs self‐powered sensing capability human motion monitoring. This work provides insights exploiting novel tribomaterials high‐output TENGs biomechanical energy harvesting, sensing, so forth.

Abstract Human civilization hinges on the capability to manipulate continuous flows. However, flows are often regulated in closed‐pipe configurations address their instability, isolating from environment and considerably restricting functionality. Manipulating open systems remains challenging. Here, capillary‐driven 3D fluidic networks (OFNs) composed of connected polyhedral frames reported. Each frame acts as a fluid chamber with free interfaces that enable entry exit; connecting rods function valves, allowing precise control over direction, velocity, path flow. The OFNs seamlessly adapt various systems, enabling manipulation multiple Leveraging these distinctive features, series applications, including selective metallization, programmable mixing diagnostics, spatiotemporal multi‐step reactions, achieved. OFNs’ also facilitate controlled drug release efficient heat exchange. These versatile will significantly advance technological innovations engineering, microfluidics, interfacial chemistry, biomedicine.

Gas-solid triboelectric nanogenerators (GS-TENGs) based on porous elastomers provide a promising avenue for the design of self-powered sensors. However, intrinsic limitation low electric output in GS-TENGs could affect accuracy and sensitivity sensing systems. Here, we develop composite by integrating an adhesive poly(siloxane-diphenylglyoxime-urethane) (PSDU) elastomer with ferroelectric (3,3-difluorocyclobutylammonium) 2 CuCl 4 [(DF-CBA) ] fillers. PSDU, intrinsically negative material alternating hard-soft segments supramolecular bonds, imparts excellent compressibility, adhesion, self-healing properties to composite. Simultaneously, incorporation (DF-CBA) as functional fillers leverages formation hydrogen bonding network enhance charge transfer processes. These facilitate accumulation through poling process, resulting power improvement that surpasses 1400 times higher than dense PSDU-based GS-TENG. Tapping onto versatile poly(siloxane-diphenylglyoxime-urethane)-perovskite (PSDU-PK) GS-TENGs, applications such hand gesture/food recognition dual-mode system have been demonstrated, suggesting their potential wearable electronics smart agriculture.
