Gait estimation using foot-pressure sensors

Along with the progress of elderly society, gait is increasingly important to live an independent life. Therefore, simple evaluation and analysis of gait is necessary. Our final goal is to propose a wearable gait analytical device. As described herein, we have estimated the floor reaction force vector using thin sensors. The floor reaction force vector during walking is the direction of the body center of gravity. Moreover, the gap with the floor reaction force vector and the body center of gravity generates a rotation moment. We used this specifically. Our evaluation method is expected to be useful for developing sensor systems.
