A novel three-dimensional force flexible tactile sensor based on pressure-conductive rubber is presented. The conductive rubber, we adopted has many excellent features. Made through "overall injection molding' technique, the sensor has good flexibility and it can be used to measure three-dimensional force. Its major principle is that we can obtain applied force through detecting pressure-conductive rubber's resistance. We describe the sensor's structure and its principle, the preliminary results of using finite element analysis and simulation will be also presented. It shows that the sensor can measure three-dimensional force accurately.
