Residual stress chevron preloading amplifier for large-stroke stiffness reduction of silicon flexure mechanisms

Simon Nessim Henein, Florent Cosandier, Loïc Benoît Tissot-Daguette, Quentin Gubler

Residual stresses can be advantageously used to permanently preload flexure micro-mechanisms in order to modify their deflection and stiffness. This paper presents a new preloading chevron mechanism (PCM) used to amplify the preloading effect of thin film ...

Gravity-Compensation Design Approaches for Flexure-Pivot Time Bases

Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann, Quentin Gubler

While flexure time bases have gained significant traction in the watchmaking industry thanks to their high quality factor and monolithic design, maintaining a stable frequency in varying orientations of wrist watches with respect to gravity remains a signi ...

Rectilinear translation four-bar flexure mechanism based on four Remote Center Compliance pivots

Simon Nessim Henein, Charles Baur, Hubert Pierre-Marie Benoît Schneegans, Loïc Benoît Tissot-Daguette, Quentin Gubler

This paper presents a novel planar four-bar linkage compliant mechanism (called 4-RCC) based on four flexure-based Remote Center of Compliance (RCC) pivots. With particular configurations and dimensions, the beam shortening of the RCC pivots can compensate ...

La géométrie du tourbillon

Simon Nessim Henein, Ilan Vardi, Roland Andreas Bitterli, Patrick Robert Flückiger, Quentin Gubler

À l'origine, le but du tourbillon était d'améliorer la chronométrie d'une montre de poche en moyennant ses positions verticales. Avec I'avènement de la montre-bracelet, le tourbillon est prisé plus pour la prouesse technique de sa réalisation que pour sa f ...
