Pick-and-placeタスクにおける指尖把握時の二指間距離を計測するセンサデバイスの開発

抄録

This report describes the development of an assessment tool for prosthesis terminal device control. The light-weight wireless tool is designed to acquire the distance between thumb and finger at tip grasping. The deformation of the sponges caused by the pinch force at each digit’s tip is measured as distance alteration. The data were collected with the tool during the pick-and-place task on both the sound hand and body-powered prosthetic hook control simulator. The experimental results showed that the device was satisfying to measure the difference of the sound and artificial hand’s digits performing the task.
