Context

In the field of mechatronic systems operating at the micro- and nanoscopic scales, our SPECIMeN team works on the reliability of perceptive functions and their associated data processing. The team’s investigations involve the development of sensors, of measurement and characterization platforms and the exploitation of measurements at the micro- and nanosocopic scales.

The issues addressed in this context are varied: modeling, design, calibration, characterization and compensation for faults and disturbances, estimation of measurement quality, high-resolution wide-scale observations and characterization of micro-objects.


Goals and Research Areas

Two principal areas are currently being explored:
› Development of platforms of micro- and nanoforce measurement for mechanical characterization,
› Development of electronic nanovision for nanorobotic analysis and characterization in a vacuum environment.


Expertise

The SPECIMeN team is highly skilled in micro- and nanoforce measurement as well as in nanovision. It can implement micro- and nanoforce sensors of varying specificities (mono- and multi-DDL, flexible or rigid, with no or negligeable inertia) some of which are unique on the international level (passive magnetic springs attached to rigid test specimens of a few milligrams) along with complete characterization stations at the micro- and nanoscopic scales.

In nanovision, the team’s research accentuates robustness in image acquisition conditions. The team first studied the SEM properties that showed the necessity of this robustness: noisy images and non-stationary distortions (drifts). It then developed robust methods of acquisition (on-line correction of drift, autofocus and visual servoing).


Implementing our work

The team’s skills are put to use in collaborative research projects, both academic and industrial. Numerous transdisciplinary projects are undertaken in partnership with FEMTO-ST’s MN2S and OPTICS Departments as well as with the Center for Medical Assistance for Procreation at the Besançon university hospital (Biom'@x); they benefit from the great potential in development and analysis offered by the MIMENTO center of technology and Equipex ROBOTEX.
