Topologically optimised flexure hinge based XY stage
SPIE Proceedings, 2017 The purpose of this study is to develop a millimeter scale two degree of freedom planar actuation mechanism (XY stage) with flexure hinges that can generate micrometer scale motion at high frequencies. To amplify the micro scale motion in X and Y directions, two identical levers are used.

Analysis of LEMs slider mechanisms based on equivalent coupling stiffness
工程科学学报, 2016 The flexure hinge is the key part to implement the movement of lamina emergent mechanisms(LEMs). Designing a flexure hinge with good flexibility and high accuracy is always the key problem to research compliant mechanisms.

Design optimization of a flexure spring used in small-sized ultra-precise optical instrument
Heliyon, 2023 Small-sized ultra-precise optical devices require compact compliant ortho-planar springs (COPS) aka. flexure springs, for precise, frictionless linear motion which depends highly on the design. A self-developed arm-hinge-linked design, named “Panto-style”

Performance optimization of large stroke flexure hinges for high stiffness and eigenfrequency [PDF]
, 2013 Two flexure hinge types are optimized for high support stiffness and high first unwanted eigenfrequency for two different working ranges, ±5.7° and ±20°. We show how multiple performance specifications lead to different designs with different performance.

Large Stroke Performance Optimization of Spatial Flexure Hinges [PDF]
Volume 6: 1st Biennial International Conference on Dynamics for Design; 14th International Conference on Advanced Vehicle Technologies, 2012 Flexure hinges inherently lose stiffness in supporting directions when deflected. In this paper a method is presented for optimizing the geometry of flexure hinges, while supporting stiffnesses are retained. These hinges are subjected to a load and deflected an angle of up to ±20°.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
