In the present paper, we aim to analyze the effect of the design parameters of micro-textured surfaces on the anti-fingerprint function. For this purpose, a numerical model of the finger contact was developed to simulate the mechanical response of the finger loaded over differently micro-textured surfaces. Interestingly, this model enables the measurement of the touched area (i.e. stained area by fingerprints). A statistical analysis was conducted using a full factorial design in order to investigate the effect of the height, width and pitch describing the surface texture. The statistical significance of the parameters effects as well as the effects of their interactions was discussed. Results have shown that both the height and the interaction between the height and the pitch have significant influences on the real area of the finger contact. An optimal compromise between the height and the pitch is recommended to reduce the touched area. The obtained results highlighted by the statistical analyses can provide a guideline for the design of anti-fingerprint surfaces.
