The purpose of this study indicates necessity of the shearing force measurement in socket for artificial foot. The measurement of force information in socket for artificial foot is difficult, and the force information is complication. Therefore, it is necessary to develop the sensor for measurement of the various force components, and the analysis for identifying the important factors such as shearing force should be conducted. In this study, we conducted the measurement experiment and analysis by hypothetical motion, and this experiment was conducted by using the artificial foot model manufactured by using the 3D printer. The motion was measured by using wireless motion sensors and compact force sensors. We extracted the components of force sensor output against the component of traveling direction. These results indicated the effect of sharing force for generating the force component of traveling direction. Hence, we can indicated the necessarily of the sharing forces sensor in socket for artificial foot.
