Sodium-ion batteries (SIBs) are expected to replace lithium-ion batteries (LIBs) as a new generation of energy storage devices due to their abundant sodium reserves and low cost. Among the anode materials of SIBs, transition metal chalcogenides (TMXs) have attracted much attention because of their large layer spacing, narrow band gap, and high theoretical capacity. However, in practical applications, TMXs face problems, such as structural instability and poor electrical conductivity. In this review, the research progress and challenges of TMXs in SIBs in recent years are summarized, the application of nanostructure design, defect engineering, cladding engineering, and heterogeneous construction techniques and strategies in improving the electrochemical performance of TMXs anode are emphatically introduced, and the storage mechanism of sodium is briefly summarized. Finally, the application and development prospects of TMX anodes in electrochemical energy storage are discussed and prospected.

The issue of sensitivity attenuation in high-pressure region has been a persistent concern for pressure-sensitive electronic skins. In order to tackle such trade-off between sensitivity and linear range, herein, a hybrid piezoresistive-supercapacitive (HRSC) strategy is proposed via introducing a piezoresistive porous aerogel layer between the charge collecting electrodes and iontronic films of the pressure sensors. Surprisingly, the HRSC-induced impedance regulation and supercapacitive behavior contribute to significant mitigation in sensitivity attenuation, achieving high sensitivity across wide linear range (44.58 kPa⁻¹ from 0 to 3 kPa and 23.6 kPa⁻¹ from 3 to 12 kPa). The HRSC pressure sensor exhibits a low detection limit of 1 Pa, fast responsiveness (~ 130 ms), and excellent cycling stability, allowing to detect tiny pressure of air flow, finger bending, and human respiration. Meanwhile, the HRSC sensor exhibits exceptional perception capabilities for proximity and temperature, broadening its application scenarios in prosthetic perception and electronic skin. The proposed HRSC strategy may boost the ongoing research on structural design of high-performance and multimodal electronic sensors.

High‐fidelity wrist pulse acquisition, essential for the early diagnosis and precise management of cardiovascular diseases, requires tactile sensors with both ultrasensitive and linear electromechanical responses. Biological Pacinian corpuscles transduce mechanical stimuli into localized strain via concentric lamellar architecture, enabling subtle and dynamic perception of pressure fluctuations. Inspired by the working mode of Pacinian corpuscles, this work presents a piezoelectric tactile sensor featuring a multilayer grooved architecture that transduces external pressure into localized in‐plane strain within the piezoelectric layer, effectively enhancing dipole alignment and charge separation. Finite element simulations and experimental results confirm that the grooved architecture contributes to strain concentration, giving rise to an ultrahigh sensitivity of 185 mV·kPa ^{− 1} and linear electromechanical response up to 300 kPa and a power density of 806 µW·cm ^{− 2} . The tactile sensor enables high‐fidelity acquisition of multi‐site pulse waveforms and accurate estimation of blood pressure, facilitating comprehensive cardiovascular assessment via heart rate variability and Poincare analysis. This bioinspired design offers an effective approach to overcoming the intrinsic limitations of piezoelectric materials and holds significant potential for developing high‐performance piezoelectric sensors for continuous, noninvasive health monitoring.
