The static grip force as a function of moisture level for the finger pads of eight subjects each involving 20 blocks of 25 trials of the type described in figure 3, which is for one of the subjects. The line is the best fit to the data and exhibits a minimum at approximately 7.75 arbitrary units corresponding to the optimal moisture level for grip. Adapted from André et al. [80].
