Analysis of Pull-in Voltage with Respect to Changes in Dielectric Material and their Thickness
Abstract: Micro Electromechanical Systems (MEMS) actuators experience pull-in effect in their actuation range. MEMS actuating elements are thin parallel plate capacitor electrodes separated with air gap. Parallel plate electrostatic micro actuators are known to have the pull-in effect, where electrostatic attractive force exceeds the mechanical restoring force of the suspending spring, and that the movable plate spontaneously pulled into physical contact with the opposite electrode. In our model the effect of …

Polypropylene Fibres in Cementitious Composites: A Critical Review of Polymer Structure, Processing, Interfacial Behaviour and Performance
Abstract: Polypropylene (PP) fibres are widely used as secondary reinforcement in cementitious composites, yet their performance is governed as much by polymer structure and interfacial chemistry as by dosage. This review synthesises 50 primary sources (2003-2025, concentrated post-2015) to examine how PP molecular structure, fibre-manufacturing history, morphology, surface properties and environmental ageing govern fibre-matrix interaction and multiscale composite performance. Isotacticity, molecular weight, crystallinity and drawing ratio are shown to set the …

Development of a Flexure Mechanism for High-Precision Applications in Scanning Applications
Abstract: The utilization of the Planar XY Flexural Mechanism is extensive in precision motion systems, where it induces relative motion between a fixed support and a motion stage through the utilization of material flexibility. In contrast to rigid link mechanisms, this mechanism presents noteworthy advantages, including zero backlash, frictionless motion, and high-order repeatability, all within a considerably more compact form. Notably, flexure mechanisms are characterized by their construction from a single …
