Abstract:
1. An implantable strain gauge comprising: a first plate; a second plate that is located at a distance from the first plate, the second plate including a window, the second plate being movable relative to the first plate from a first position to a second position upon application of a tension to the strain gauge, the first and second plates being configured to be implanted within tissue; a luminescent material, the luminescent material emitting a detectable emission upon excitation by irradiation, the emission of the luminescent material being detectable through the tissue, wherein at the first position the emission of the luminescent material is detectable through the window and at the second position either no luminescent emission is detectable through the window or a second luminescent emission is detectable through the window that differs from the emission detected through the window at the first position.
