Abstract The unique selective ion‐transport characteristics of nanofluids make them applicable in energy harvesting and sensing. However, developing scalable, self‐powered nanofluidic devices remains challenging due to high cost, processing complexity, reliance on external power sources. In this work, surface‐twisted, internally aligned algae fibers (twisted fibers) are fabricated using an asymmetric flow field regulate the assembly process cellulose nanofibers. Unlike from symmetrical process, flow‐mediated twisted exhibit a significantly reduced diameter (33.6–20.4 µm), increased packing density (0.87–1.47 g cm −3 ), superior fractured stress (249.4–468.5 MPa), enhanced Herman's orientation parameter (from 0.77 0.89). Importantly, demonstrate energy‐harvesting up 12.87 W m −2 under 50‐fold salinity gradient can serve as urine monitors, effectively distinguishing infants' urination motility behaviors alerting saturation ionic conductivity (7.8 mS −1 ) at dilute electrolyte concentrations. This study provides novel design concept for biomass‐based health sensing system.

Abstract The advancement of nanofluidic membranes is critical for mimicking bioelectrogenic ion‐channel mechanisms and boosting output power density, essential sustainable energy applications. conversion efficiency these devices significantly relies on the ion conductivity permselectivity membranes. Membranes with aligned one‐dimentional (1D) pores, high pore organized dangling ionic groups are theorized to offer superior permeability selectivity, yet configurations remain underexplored. Herein, successful fabrication oriented covalent organic framework (COF) presented. These exhibit precisely cationic anionic sites within their channels, achieved through post‐synthetic modification using click chemistry, which shows conductivity. When incorporated into full‐cell thermo‐osmotic generators, deliver an impressive density 195 W m −2 under a 50‐fold salinity gradient (NaCl: 0.01 ‖ 0.5 ) along 35 K temperature differential. This substantially increases 2.41 times 471 −2 when enhanced tenfold, surpassing performance existing similar conditions thus offering promising avenue enhancing in resource utilization.

Abstract Osmotic energy, also called blue promotes sustainable energy development. Nanofluidic membranes constructed from various nanomaterials applied in reverse electrodialysis play an important role enhancing the effective osmotic conversion.
