Matricial sensor of contact strengths

The developed innovation allows to answer the above-mentioned limits. It is based on a set of cells filled with an elastic polymer, the measurable deformation of which is proportional to the applied strength. To measure the deformation of this material, the position of a reflective ball includes in the material is determined by triangulation thanks to an optical system. An algorithm allows, from the various intensity measured, to reconstruct, after calibration, the effective strength applied to a given cell, at the given moment.
