The sample measured is a replica of the skin on a fingertip. In this case, the difficulty of holding one’s finger still during the measurement necessitates using the indirect method of measuring on replicas. The objective was to obtain information for simulation of microgeometry of skin to be able to create a simplified virtual model.
The model was going to be used in finite element analysis (FEA) regarding the propagation of transient vibrations from handheld equipment, such as impact wrenches and chisel machines, through the skin to the nerves where damage occurs.

Conclusion
Using the confocal technique, the 20X brightfield objective lens, and extended measurements, we were able to measure the skin geometry with a high enough resolution and sufficient reliability to draw general conclusions regarding the size, height, and distribution of the ridges and lines of the skin. With this data, we were able to make a simplified model of the skin for successful use in FEA.
