 Hi, my name is Anika and I'm a PhD student at the University of Virginia. Phonphile monofilaments are a clinical tool used worldwide to assess touch deficits. In this work, we evaluated mechanical states of skin deformation by low force monofilaments using a non-contact optical tracking method called 3D digital image correlation. In this video, you can see a slight movement of the skin at the base of the monofilament during indentation and the associated strain and displacement fields that are measured.
