Device capable of detecting a bearing force

A device capable of detecting a bearing force exerted in a direction of indentation, wherein the device comprises:

• a support rigid by tension,
• at least one plate which extends from a proximal end mounted on the support, to a free distal end, this plate being 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,
• to a more flattened conformation in which the convex bearing face is more flattened,
• a spring capable of permanently straining the plate to its bent conformation such that, after disappearance of the bearing force, the plate automatically reverts to its bent conformation,
• a guiding mechanism also mounted on the support and capable, in response to the deformation of the plate, 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, this sensor being fixed to the proximal end with no degree of freedom in translation along the translation axis.
