As people grow older, the ability to walk becomes ever more important to live an independent life. A simple system that is useful for evaluation and analysis of gait is necessary. Our goal is to design a wearable gait analyzer. In this study, we estimated the floor reaction force vector using an ultra-thin pair of wearable sensor pads. The floor reaction force vector, when someone is walking, is in the direction of the body's center of gravity. The gap separating the floor reaction force vector and the body's center of gravity generates a rotation moment, which is what we used to create this equation. Our evaluation method will be useful for future development of sensor systems.
