Advanced Intelligent Systems, EarlyView.A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

Electrostatic Actuation Induces Competing Adhesion and Vibration Regimes at Fingertip Contact
Advanced Intelligent Systems, EarlyView.Electric fields modulate fingertip–surface contact to create artificial touch sensations. The mechanisms underlying electrostatic friction, however, remain unclear. Direct imaging and friction measurements under oscillating electric fields showed that adhesion dominates at high frequencies, while vibration contributes substantially at the lower ...

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing
Advanced Intelligent Systems, EarlyView.The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Development of Piezoelectric Semi-active Friction Damper
, 2011 [[abstract]]於結構減震控制技術中，藉由摩擦原理消散地震能量，已證實可大幅提升結構物之抗震能力，各式摩擦阻尼器亦已應用於實際工程案例中。唯一般被動阻尼器之使用，須於各個樓層皆安裝阻尼器以增加其消能能力，如此阻尼器之用量亦隨之增多。為改善以上問題，並提升阻尼器之效能，因此有半主動摩擦阻尼器之發明。本文研發一兼具被動與半主動性能之壓電式摩擦阻尼器並推導其設計公式。又因為壓電材料具有出力大、響應快等優點，因此選取為本文阻尼器之正向力控制元件，以達到控制阻尼器遲滯行為之目的 ...

Modelling a friction damper: analysis of the experimental data and comparison with numerical results
, 2006 High cycle fatigue is one of the main causes of failure of blades in turbomachinery. The negative impact of HCF on turbomachinery blades can be reduced by dry friction vibration damping. A typical application of dry friction damping in gas turbine is the
