System For Sensing a Mechanical Property of a Sample

摘要

A sensing element for sensing a mechanical property of a sample defining a sample surface using a contact force exerted the sample surface. The sensing element includes: a deformable element defining a contact surface and a deformable section in register with the contact surface, the deformable section being deformable between an undeformed configuration and a deformed configuration; a deformation sensor operatively coupled to the deformable section for sensing and quantifying a deformation of the deformable section between the deformed and undeformed configurations, the deformation sensor being an optical deformation sensor; and a force sensor operatively coupled to the deformable element for sensing the contact force exerted on the contact surface.
