Touch is a complex sensory system involving a high density of mechanoreceptors in the fingertips, which provide crucial information about the environment, such as an object's geometry, texture, and mechanical properties, as well as the nature and magnitude of interactions, offering continuous feedback during grasping and dexterous manipulation. In particular, the activity of tactile afferents has been linked to local skin deformations in the finger pad. This Master's thesis project was conducted at the Institute of Neuroscience (IoNS) of the Université catholique de Louvain, where previous studies employed a robotic platform to investigate local tangential strains of the fingertip during controlled interactions with flat transparent surfaces, enabling the acquisition of images of the skin during contact.
