However, mechanical clearance and collision introduce significant dispersion in operating time. Moreover, because the operating time lies on the millisecond scale, conventional closed-loop control methods face prohibitively complex implementation challenges. To address this issue, this study develops an analytical model of the fast mechanical switch driven by an ultrasonic motor and proposes a Support Vector Regression (SVR)-based prediction model to characterize and compensate for operating time dispersion via a delayed-start strategy. The analytical model provides the theoretical operating time and identifies key working parameters. The SVR-based prediction model then estimates the actual operating time. The required delayed-start time corresponds to the difference between the theoretical and predicted operating times. Unlike traditional closed-loop control, which demands high-frequency sampling and real-time computation of control laws, the proposed method only requires offline prediction of operating time based on observed data, followed by determination of the delayed-start interval. Experimental results demonstrate that this approach controls operating times within 23 ± 0.15 and 25 ± 0.15 ms, satisfying the phase control requirements for the fast mechanical switch. This performance surpasses the current operating time dispersion control of ±0.2 ms achieved in Thomson-coil-driven mechanical switches.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148405608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of efficient and reliable non-destructive testing methods is crucial for structural health monitoring of CFRP. This study proposes a novel non-contact eddy current testing (ECT) approach utilizing a transmit-receive (T-R) probe equipped with a figure-eight transmitter coil to mitigate lift-off interference. To achieve simultaneous enhancement of spatial resolution and detection sensitivity, a multi-objective optimization framework for the probe structure is established. Due to the lack of an explicit mathematical model for the induced-voltage amplitude of the receiver coil, this study develops a Back Propagation_Kriging predictive model to accurately approximate the response. Guided by this model, an improved multi-objective particle swarm optimization algorithm combined with an entropy-weighted technique for order preference by a similarity to ideal solution scheme enables an effective balance between spatial resolution and detection sensitivity. Simulation analyses combined with experimental measurements show that the optimized probe delivers finer spatial resolution and a pronounced improvement in detection sensitivity, demonstrating the effectiveness and robustness of the proposed optimization framework for advanced ECT probe design.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148423709","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the cracking response of ultra-weak fiber Bragg grating (UWFBG) sensors in asphalt mixture remains ambiguous, limiting their practical application in road monitoring. This paper explores the crack response characteristics of UWFBG sensors to enable effective crack detection in asphalt mixtures using crack, cutting experiment, and numerical analysis. The numerical results show that the mortar-UWFBG interface is the weakest region within the asphalt mixture. The experimental results show that these UWFBG sensors can quantitatively measure cracks with widths ranging from 0.46 to 5.75 mm, exhibiting a strong linear correlation between wavelength and actual crack width, which agrees with the numerical analysis results. Furthermore, the experimental results show that they are capable of detecting cracks as narrow as 0.5 mm.

Here, we propose a universal hybrid micro/nanofabrication strategy and demonstrate its capability through the fabrication of ultrashort, ultrathin SCD cantilevers that overcome key performance limits in high-speed atomic force microscopy (HS-AFM). By combining high-throughput angled laser micromachining with nanoscale focused ion beam refinement, we achieve precise geometric control while preserving crystallinity and nanometer surface flatness, with drastically reduced material removal and fabrication time. This approach enables the direct fabrication of free-standing SCD cantilevers with dimensions of ∼7 × 2 × 0.08-0.15 μm3. By integrating amorphous carbon tips via electron-beam-induced deposition, fully functional HS-AFM probes are realized. The fabricated probes exhibit resonance frequencies of 3.7-6.0 MHz-3-4 times higher than commercial quartz-like cantilevers-while maintaining spring constants suitable for soft-matter and biological imaging. Using the fabricated SCD probe, HS-AFM imaging of actin filaments achieved stable acquisition at 25 fps. This scalable and versatile method opens new opportunities for ultrafast HS-AFM and broadly enables high-performance diamond nanostructures for nanomechanical sensing and micro- and nanoelectromechanical systems.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148536374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The technique has also opened up a new dimension for cryo-EM sample preparation, making it possible to deposit compounds onto a cryo-EM sample while it is frozen, so that upon flash melting, the embedded particles experience an altered environment. For example, we have recently shown that depositing ultrathin silicon dioxide membranes onto a cryo-EM sample causes particles to detach from the interface upon flash melting, removing preferred particle orientation. Here, we describe an apparatus for physical vapor deposition of compounds onto cryo-EM samples, detailing its design and operation. As a demonstration, we determine that the minimum thickness of silicon dioxide sealing membranes in a laser flash melting experiment is just over two monolayers. Moreover, we show that it is possible to deposit reagents onto the cryo-EM and induce mixing during flash melting, which points toward a new strategy for initiating protein dynamics in time resolved experiments. We propose that the design of our instrument can form the basis for an integrated platform for microsecond time-resolved cryo-EM experiments.","PeriodicalId":21111,"journal":{"name":"Review of Scientific Instruments","volume":"97 7","pages":""},"PeriodicalIF":1.6,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148606815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
