This paper designs a new robot flexible tactile sensor that can measure three-dimension force based on flexible pressure-sensitive conductive rubber. It studies on the piezoresistive effect of pressuresensitive conductive rubber, illustrates on the designing thoughts of tactile sensor, and researches on the tactile sensor's unit design and array structure respectively. It obtains the mathematical model of calculating three dimension forces, and gains the verification of three dimension force by experiments. The results indicate that the designed three-dimension force flexible tactile sensor for robot has the advantage of simple design, low costs and fine flexibility. Besides, it can be disposed in array to acquire the information of three-dimension force in medication, physics and robots.
