The advancement of nanofluidic membranes is critical for mimicking bioelectrogenic ion-channel mechanisms and boosting output power density, essential for sustainable energy applications. The energy conversion efficiency of these devices significantly relies on the ion conductivity and permselectivity of the membranes. Membranes with aligned one-dimentional (1D) pores, high pore density, and organized dangling ionic groups are theorized to offer superior ion permeability and selectivity, yet these configurations remain significantly underexplored. Herein, the successful fabrication of oriented ionic covalent organic framework (COF) membranes is presented. These membranes exhibit precisely aligned cationic and anionic sites within their pore channels, achieved through post-synthetic modification using click chemistry, which shows high ion permselectivity and conductivity. When incorporated into full-cell thermo-osmotic generators, these membranes deliver an impressive output power density of 195 W m−‍2 under a 50-fold salinity gradient (NaCl: 0.01 m ‖ 0.5 m ‖ 0.01 m) along with a 35 K temperature differential. This power output substantially increases 2.41 times to 471 W m−2 when the salinity gradient is enhanced tenfold, surpassing the performance of existing nanofluidic membranes under similar conditions and thus offering a promising avenue for enhancing efficiency in energy and resource utilization. © 2025 Wiley-VCH GmbH.

Accurately recognizing gait phases, by applying proper instrumentation and measurement, is significant in walking rehabilitation training for patients with impaired mobility. In this study, seven phases of complete stand-walk-stand cycle as well as continuous daily walking were recognized based on muscle synergy and PSO-CNN-LSTM model. Firstly, the complete stand-walk-stand walking cycle were divided into starting phase, terminal swing phase, loading response phase, mid-stance phase, terminal stance phase, initial swing phase, and stopping phase, based on the features of surface electromyography (sEMG) collected by portable sEMG acquisition system and measured motion data of lower limb. Secondly, a muscle weight matrix and an activation sequence matrix were calculated by using non-negative matrix factorization (NMF). Finally, a PSO-CNN-LSTM network was designed to recognize the complete stand-walk-stand cycle by applying above mentioned matrices as input. Fourteen subjects volunteered to perform linear walking experiments under procedure to verify the feasibility of the proposed approach by comparing results with other classifiers and features. Experimental results show that the proposed approach was capable of achieving an average recognition accuracy of up to 85.384%. This work will offer promising gait recognition method for rehabilitation robots to achieve natural and flexible human-robot interaction. © 2001-2012 IEEE.

Biological ion channels achieve remarkable permselectivity and cation discrimination through the synergy of their intricate architectures and specialized ionophores within confined nanospaces, enabling efficient energy conversion. Emulating such selectivity in synthetic nanochannels, however, remains a persistent challenge. To address this, a novel host-guest assembly membrane is developed by incorporating sodium-selective ionophores into a β-ketoenamine-linked covalent organic framework (COF). This design confers exceptional permselectivity and Na+ selectivity, achieving Na+/K+ and Na+/Li+ selectivity ratios of 3.6 and 103, respectively, along with near-perfect Na+/Cl− selectivity under a 0.5 M || 0.01 M salinity gradient. Notably, the membrane dynamically switches its permselectivity to favor anion transport in the presence of high-valent cations (e.g., Ca2+), overcoming limitations such as uphill cation diffusion and back currents observed in conventional cation-selective membranes. This adaptive behavior yields a 4.6-fold increase in output power density in Ca2+-rich environments. These findings advance the design of biomimetic nanochannels with unparalleled ion selectivity and enhanced energy conversion efficiency. © 2025 Wiley-VCH GmbH.
