AS2M Uncertainty evaluation associated to small forces generation between 100 nN and 100 µN with magnetic springs

The PhD thesis is proposed within the framework of the ANR TRAFALDA project, which started on February 29, 2024. This project is carried out in collaboration with the French metrology. The FEMTO-ST Institute is the project leader. The ambition of the TRAFALDA project is to demonstrate that the French metrology is capable to deal with a new range of forces below 100 µN in a way that is traceable to the SI, and that it can implement a metrological calibration approach for small force measurements in a specific case of biomechanical characterization.

It deals with the uncertainty evaluation associated to small forces generation between 100 nN and 100 µN with magnetic springs – Application to the calibration of a platform dedicated to the mechanical characterization of human oocytes for in

Keywords: small forces generation, force metrology, uncertainty estimation, magnetic springs, mechatronics, instrumentation, observation and control theory, human oocyte characterization

Location: FEMTO-ST Institute, Besançon, France, in the ROBIMSS team of the AS2M department. This team has developed genuine expertise in the generation of small forces of less than 100 µN using self-stabilizing magnetic springs for small-scale mechanical characterization. It is also interested in the metrology of small forces, in order to quantify the quality of forces generated or measured.

Application: open until the end of April 2024.

Starting date: between June and October 2024.

MN2S : Effect of environment gaseous contamination on dry lubrication – In space applications

Partners: The PhD thesis is a collaboration between the French Space Agency (CNES, https://cnes.fr/fr/), ADR Alcen (https://www.adr-alcen.com/en), and Institut FEMTO-ST (https://www.femto-st.fr/en), under CNES PhD program.
Location: FEMTO-ST Institute, Besançon, France, in the Micro-Nano Sciences and Systems Department (MN2S). The MINAMAS (Micro-Nano Materials and Surfaces) team specializes in the physical, and tribological study of thin films, nanomaterials and solid/gas interaction. It has developed strong expertise in multi-environment lubrication, and nanomechanical characterization of tribological materials, particularly for space mechanisms.

Starting date: October 2024
Application: online on https://recrutement.cnes.fr/fr/annonces from February 1st to March 15th, 2024, subject REF : 24-129
