The purpose of this report is to introduce and discuss about the design parameters for a segment of a tactile sensor which will be used to read one dot of a braille alphabet. A single segment of a tactile sensor, consisting of a piezoelectric (PVDF) film sandwiched between two elastic materials, is designed. The design parameters, regarding the geometry and Young's modulus of the sensor are introduced. Simulations are used to investigate the influence of the design parameter on the sensor output, and to show the design criterion in order to obtain enough large sensor output. The results show that 1) for obtaining enough large sensor output, the layer, which is closer to the contact point with the dot of a Braille alphabet, should be "thinner" than and have a "similar hardness" to the other layer, 2) the output of sensor is mostly dependent on the bending effect near the PVDF layer and the Clamped structure can encourage more bending.
