Walking analysis by 6-axis force sensor for simultaneous measuring of plantar deformation

This paper presents a result of walking experiment 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 result of assessment experiment of the sensor is described.
