To design a tactile sensor that can measure direction and distribution of force, common strategy is to add a mechanical tab on top of four sensing elements. The tab translates force direction information to the sum and difference of the elements' output. However, quantitative criteria for the evaluation of the sensor has not been proposed. In this paper, we propose to use singular value decomposition (SVD) to measure S/N ratio and gain at the same time. We also applied the proposed criteria to optimally design the reflector pattern of the optical type tactile sensor.
