Abstract
The present disclosure provides a device for evaluating a mechanical property of a material. The device comprises a sensing layer that has a contact surface for contacting a surface area of the material. The sensing layer has a property or dimension that is pressure sensitive. The device also comprises a detector arranged to detect electromagnetic radiation that propagates through at least the sensing layer. The device is arranged such that, when the contact surface of the sensing layer is in contact with the surface area of the material and a load is applied on at least a portion of the surface area of the material, the detected electromagnetic radiation can be used to determine stress within a portion of the sensing layer, the determined stress being indicative of the mechanical property of the material.
