Here, we reveal a previously overlooked carrier-mediated acoustic leakage mechanism in piezoelectric-semiconductor heterostructures. By developing an electromechanical-carrier coupling model, we demonstrate that interfacial carrier accumulation reconstructs electrical boundary conditions, causing piezoelectric fields to penetrate into non-resonant regions. The resulting electric field distortion activates parasitic mechanical vibrations, which radiate bulk acoustic waves into the silicon substrate and degrade the quality (Q) factor. Ultrafast femtosecond laser pump-probe spectroscopy is further employed to characterize carrier dynamics, establishing a quantitative link between carrier modulation and acoustic performance. Guided by this mechanism, multiphysics decoupling strategies based on material engineering and electric field engineering are developed to suppress carrier-mediated acoustic leakage. By reconstructing electrical boundaries through defect-state modulation and asymmetric electrode design, the Q factor of piezoelectric-semiconductor devices is substantially enhanced while maintaining compatibility with standard fabrication processes. This work reveals an unconventional role of semiconductor carriers as mediators of acoustic energy redistribution and provides a mechanism-guided strategy for designing high-performance heterogeneously integrated micro/nano devices.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e71103"},"PeriodicalIF":8.7,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149163804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Magnetic field actuation, as a non-invasive and highly biocompatible driving method, has become a research hotspot. However, traditional magnetic functionalization methods like magnetron sputtering suffer from complex processes, high costs, and poor biocompatibility. Meanwhile, the mixture method combining magnetic particles with photoresist is constrained by particle dispersion and molding quality. To address these challenges, this study developed a low-cost, rapid, efficient, uniform, and stable magnetic coating method for Fe3O4 nanoparticles. This technique utilizes a rotating magnetic field to rapidly transport and concentrate Fe3O4 nanoparticles around the photoresist microstructure, where the kinetic energy imparted by the magnetic field forcefully overcomes interfacial electrostatic repulsion, allowing strong van der Waals forces to drive their firm and uniform adhesion within 5 min. Systematic experiments demonstrate that this method exhibits outstanding performance in particle attachment uniformity, motion stability, durability, and biological environments. Its motion capabilities are comparable to those achieved by conventional magnetron sputtering, providing significant reference for the functional design and biomedical applications of magnetic micro/nanorobots.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e71102"},"PeriodicalIF":8.7,"publicationDate":"2026-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149164212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrating self-healing functionality into triboelectric substrates is an effective approach to address these bottlenecks, but it remains challenging to simultaneously realize superior stretchability, steady electrical output, and efficient self-healing performance in a single material system. Inspired by the arm structure of brittle stars, a waterborne polyurethane (WPU) incorporating dynamic disulfide and hydrogen bonds was fabricated, and the hydrogen-bonding interfacial network between MXene and WPU was tailored. A composite system enabling synergistic multilevel energy dissipation through reversible dynamic bonds and disulfide exchange was therefore constructed. The resulting MXene/WPU (M-WPU) composite film exhibits a tensile strength of 14.7 MPa, an elongation at break of 970%, a triboelectric output of 14 µA, and a self-healing efficiency of 89% after thermal healing at 100°C for 12 h. The flexible sensor assembled from this M-WPU film, integrated with machine learning, enables accurate handwriting recognition and human-machine interaction. Notably, after macroscopic crack self-healing, the M-WPU can still maintain stable electrical signal output, offering novel design insights for the development of long-life, highly reliable self-powered flexible sensors.","PeriodicalId":229,"journal":{"name":"Small Methods","volume":" ","pages":"e71107"},"PeriodicalIF":8.7,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149134411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MAP induces controlled matrix etching to expose and reorganize the fluorosilane-modified SiO2 framework, thereby coupling hierarchical roughness, fluorinated surface chemistry, and structural stabilization. The resulting coating exhibits water and oil contact angles of 168° and 155°, respectively, and repels diverse solutions, suspensions, and emulsions.
