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

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

A load cell with adjustable stiffness and zero offset tuning dedicated to electrical micro- and nanoprobing

Simon Nessim Henein, Charles Baur, Loïc Benoît Tissot-Daguette, Etienne Frédéric Gabriel Thalmann, Michal Stanislaw Smreczak

The tasks of electrical micro- and nanoprobing require precision that goes beyond human perception and therefore, depend on sensors providing real-time feedback. Efforts towards automation in micro- and nanoprobing and emerging areas such as branched nanow ...

Analytical modeling and experimental validation of rotationally actuated pinned–pinned and fixed–pinned buckled beam bistable mechanisms

Simon Nessim Henein, Loïc Benoît Tissot-Daguette, Hubert Pierre-Marie Benoît Schneegans, Etienne Frédéric Gabriel Thalmann

Buckled beams have become key building blocks in compliant mechanisms to achieve nonlinear behaviors, such as bistability, constant-force and stiffness tuning. However, designing and modeling such components is challenging due to their highly nonlinear cha ...

The Dimension of the Body in Higher Education: Matrix of Meanings in Students’ Diaries

Simon Nessim Henein, Ramiro Tau

In this paper, we attempt to show some consequences of bringing the body back into higher education, through the use of performing arts in the curricular context of scientific programs. We start by arguing that dominant traditions in higher education repro ...

Triple Crossed Flexure Pivot Based on a Zero Parasitic Center Shift Kinematic Design

Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann

Thanks to their absence of play, absence of contact friction and possible monolithic fabrication, flexure pivots offer advantages over traditional bearings in small-scale, high accuracy applications and environments where lubrication and wear debris are pr ...

Active load cell with positive, negative and zero stiffness operating modes for micronewton range contact force monitoring in electrical probing

Simon Nessim Henein, Charles Baur, Hubert Pierre-Marie Benoît Schneegans, Michal Stanislaw Smreczak

This article describes a novel method for applying a contact force in the range of 1 to 100 μN with pointed probe on a microscale sample in order to perform ohmic electrical measurements. The solution is based on the new TIVOT active load cell combining th ...

Flexure pivot based system

Simon Nessim Henein, Loïc Benoît Tissot-Daguette, Benoît Dagon, Michal Stanislaw Smreczak

Flexure pivot based system (1) being one of: a force sensor, a force limiting device arranged to exert a predetermined threshold force, a torque limiting device arranged to exert a predetermined threshold torque, a programmable mechanical memory, or an acc ...

La géométrie du tourbillon

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

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 ...

Optical rotating torque sensor with nano newton-meter resolution based on a hanging torsion wire

Simon Nessim Henein, Etienne Frédéric Gabriel Thalmann, Billy Nussbaumer

This article presents a novel torque measuring setup working in the nano newton-meter range. The central novelty is a long (1 meter range) thin (diameter of a few tens of micrometers) metallic wire used instead of the relatively stiff torsion zone of the s ...
