We have previously proposed the basic structure of a detector of surface defects (tiny protrusions), such as dirt in paint, on smooth hard surfaces. The detector incorporates a single force-sensing resistor film (FSRF) covered with two elastic sheets. This paper presents finite element analyses on the detector mechanism. The analyses suggest that the detector's capability depends on the stiffness of the backboard through which the FSRF is pressed and on the distribution of the pressing force.
