Development and calibration of 6-axis force sensor for simultaneous measuring of plantar deformation

This paper presents a design concept of a novel 6-axis force sensor with simultaneous plantar deformation measurement by high-speed cameras under the sensor is presented. The sensor is based on two custom beams and some strain gages in order not to be limited a view of the high-speed cameras. In walking analysis research field, the 6-axis force and plantar skin deformation are very important factors to identify the risk of fall and to reduce risk of fall-related injuries in elderly populations. However, there were no sensor can measure 6-axis force and plantar skin deformation simultaneously. In this paper, the design of the sensor is described and perpendicular axis calibration results are shown. Furthermore, the walking experimental results show that the development sensor can be used for walking analysis.

Plantar 3-axis distributed forces sensor based on measurement of silicone rubber deformation for walking analysis

We focus tactile stimulus on a sole during walking to clarify mechanisms of fall and walking adapted for irregular terrain. Therefore, this paper proposes the development of the novel optical forces sensor which can measure 3-axis distributed forces acting on a sole during walking. This sensor can measure how much force in which direction a sole loads the floor in detail when human walks. The construct of the 3-axis distributed forces sensor using silicone rubber is reported. To measure the 3-axis distributed forces, the sheet of silicone rubber which has many circular truncated cone projections is developed. To detect 3-axis forces from the deformation of a projection by High-speed cameras, we conducted experiments to verify the relation between the force and the deformation of a projection. From results of experiments, 3-axis forces can be detected from the deformation of a projection.

Manufacture and proofreading of 6-axis force sensor for walking analysis

In this research, it has aimed at the development of the walking analysis device that takes the influence that the sense machine gives into consideration. The production of six axis power sensor that is the floor reaction force meter to which the use simultaneously with the acquisition of the image of the skin transformation of the back of the foot is required and the evaluation method are described for that.
