Development of a Worker-Wear Assistance Suit with Tunable and Concealable Elastic Structure

抄録

Due to the injuries of workers in several industries, such as nursing and construction, we developed a tunable and concealable worker-wear assistance suit consisting of elastic components to prevent the fatigue and injuries of the arm muscle for the workers whose arm repeatedly perform a motion upon their shoulder. By measuring the muscles activities of three subjects wearing this suit and lifting a load of 10 kg to practically verify the functionality of the suits, the results showed 43% improvement ratio at most on their arm muscles. The proposed assistance suit can not only directly support and assist the elbow and shoulder joint but also indirectly prevent the lower back injury.
