    摘要：With the rapid development of wearable electronics， intelligent sensing， and flexible interactive technologies， human-machine interfaces are demanding increasingly real-time， intuitive， and convenient modes of information feedback. As an emerging platform for human-machine interaction， alternating current electroluminescence-based visual sensors can directly convert external stimuli into optical signals， thereby advancing the development of human-machine interaction. However， existing visual sensors generally rely on external alternating current excitation and still suffer from limited flexibility， insufficient system integration， and an inadequate ability to convert weak stimuli into clearly discernible visual signals. To address these issues， this paper presents a humidity-sensitive visual film sensor based on field-induced luminescence. The sensor adopts a multilayer flexible architecture consisting of a skin-adhesive layer， a conductive layer， a luminescent layer， and a sensing layer. Within the relative humidity （RH） range of 40%-95%， the sensor exhibits a pronounced high-contrast optical response at an ionic liquid （［EMIM］［TFSI］） mass fraction of 2%. Owing to its excellent conformability， flexibility， and stretchability， it can be stably laminated onto the human body and readily accommodate complex deformations. By integrating alternating-current electroluminescence with a humidity-responsive gel， we established a humidity-induced luminescence mechanism that enables direct visual readout of humidity variations. Meanwhile， through an energy-transfer pathway established between the human body and the ambient electromagnetic field， the film can be wirelessly driven without the need for a conventional rigid power supply， thereby improving both portability and operational versatility. Furthermore， by exploiting the natural humidity of human skin， the film enables contactless visual interaction， offering a new design strategy for flexible， wireless， and perceptive human-machine interfaces， and demonstrating its potential for applications in smart interactive displays and wearable electronics.

    摘要：Mechanoluminescence， the light emission of solids under mechanical actions， presents broad application prospects due to its unique advantages of self-powering capability， visualized response， and high sensitivity. This review highlights the emerging applications of mechanoluminescent materials in self-powered sensing， engineering structural health monitoring， information security， and biomedical imaging. Strategies for enhancing brightness and spectral regulation are briefly discussed， alongside current challenges such as insufficient mechanistic understanding. Future opportunities in flexible electronics and intelligent sensing are also envisioned. These insights aim to provide valuable references for advancing the practical implementation of mechanoluminescence technologies.

    摘要：Tactile sensing is essential for high-dimensional perception in embodied intelligence， yet conventional electrical sensors are limited by complex readout， electromagnetic interference， and restricted imaging resolution. Mechanoluminescence materials， which directly convert mechanical stimuli into optical signals， offer a promising alternative for visualized and interference-resistant tactile sensing. This review summarizes recent advances in ML materials for tactile sensing， focusing on key performance metrics and optimization strategies， including sensitivity enhancement， improved cycling stability， extended sensing range， and signal-to-noise ratio optimization. Progress in high-resolution tactile imaging and multimodal sensing is further highlighted. Representative applications in electronic signatures， artificial skin， human-machine interfaces， and soft robotics are discussed. Finally， critical challenges， including static stimulus response， multimodal signal decoupling， and system integration， are analyzed. This review provides insights into the design of next-generation ML-based tactile sensing systems.

    摘要：Metal halide perovskite light-emitting diodes have advantages such as high color purity， wide color gamut， and facile solution processability. In recent years， their performance has developed rapidly， and the external quantum efficiency of the devices has exceeded 30%. “Core/shell” perovskite nanocrystals are particularly effective in improving luminescent properties and stability because of their unique architecture and customized semiconducting properties. A major focus in this review is the classification of “core/shell” perovskite nanocrystals and the mechanism by which the shell affects the perovskite. This review then summarizes how shell coating strategies improve the performance of perovskite materials and devices， along with recent progress in this area. We also discuss the difficulties and challenges of shell-coating technology for fulfilling efficient and stable perovskite light-emitting diodes， and offer an outlook on future development directions.
