Cyclic pressure loading over time for the FEA on the 3D models (top) with single node stress responses for the epidermis and dermis layers of the 3D modeled human fingertip (middle) and the corresponding upper and lower sensing layers of the synthetic skin (bottom). The relative stress between the upper and lower layers of the synthetic skin matches that of the epidermis (upper) and dermis (lower) of the simplified fingertip model.
