This paper proposed a flexible tactile sensor using a flexible wiring, which was laminated copper and polymer. A urethane gel of low Young's modulus material was filled in the gap between the electrodes. This sensor can be achieved high sensitivity and wide load range due to thin urethane gel. The sensitivity, resolution, load range in linear sensitivity, and load capacity of fabricated sensor were 0.5 pF/gf, 0.1 gf, 100 gf, and 900 gf, respectively. The waiting time until the electrode returned to an initial position was 10 min. When the sensor was set on a circular pillar (10 mm in diameter), the sensitivity and resolution were 0.45 pF/gf and 1 gf, respectively.
