空気圧人工筋肉を用いた姿勢維持装置の開発

抄録

In this study, we have developed a device that supports a wide range of parts from the back to the waist, which was difficult to support strongly until now. Especially, the forward leaning motion is often used in daily life, but it is a typical motion that makes it difficult for a person having back pain. If such a part is overloaded and damaged, it may cause a serious accident. Therefore, a support device that uses a force amplified by a speed reducer or a lever is dangerous. Therefore, we developed a device that uses air pressure for bending to avoid overloading and to assist by returning to the correct posture. As a result, we were able to propose a device that can assist in raising the upper body by fixing the curvature of the spine in a correct state by manufacturing artificial muscles for contraction, spine for correction, and parts for the waist. It was also found that performing performance evaluation experiments can realize support that does not overload the human body.
