Morphology of a human finger pad during sliding against a grooved plate: A pilot study

This pilot study shows that Optical Coherence Tomography can be used to capture the morphology of the finger pad during sliding interaction with a grooved plate. The videos show how the finger pad ridges deform to slide or compress closer to the edge of the grooves. This study has demonstrated the future possibilities of investigating and visualising the interaction of a finger pad with a plate specimen of controlled roughness to improve and optimise surface characteristics of consumer products.
