An illustrative device capable of detecting a bearing force includes a support rigid by tension and at least one plate that is elastically deformable by the bearing force from a bent conformation in which the plate exhibits a convex bearing face on which the bearing force to be detected is directly exerted and to a more flattened conformation in which the convex bearing face is more flattened. The illustrative device further includes a spring capable of permanently straining the plate to its bent conformation, a guiding mechanism mounted on the support and capable of guiding the free distal end of the plate in translation along a translation axis at right angles to the direction of indentation, and a sensor capable of detecting a displacement of the free distal end along the translation axis to detect the bearing force.
