Smart Force Sensors And Its Applications

Two kinds of smart force sensors for the force distribution measurements are presented in this paper. The force distribution testing technique is widely used in intelligent control of robot and biomechanics. Usually a sensor matrix that includes hundreds to thousands micro sensor elements is adopted and that will provides the precise force distribution information for the di different requirements. Two kinds of sensor material the piezoelectric ceramic, PVDF and piezo-resistance sensor conducting rubber are introduced in this paper. The requirements of the smart structure and the signal processing technique are discussed. Three smart force sensor systems are developed for the robot and biomechanics applications. Some image processing techniques are developed for the signal analysis and data processing.
