“…The device has many more degrees of freedom that can satisfy various activities of the human body, which is mainly used for assistance by medical personnel. Other studies [14] have introduced a wearable stoop assist device which can decrease waist erector spinae activity during stooped work. This type of equipment is mainly controlled by two tension bands.…”

The purpose of this study was to develop a wearable waist exoskeleton to provide back support for industrial workers during repetitive lifting tasks and to assess reductions in back muscular activity. The ergonomic mechanical structure is convenient to employ in different applications. The exoskeleton attaches to the wearer’s body with 4 straps, takes only 30 s to put the exoskeleton on without additional help, weighs just 5 kg and is easy to carry. The mechanical clutch can assist the wearer as needed. Inertia Measurement Unit (IMU) was used to detect wearers’ motion intention. Ten subjects participated in the trial. Lower back muscle integrated electromyography (IEMG) of the left and right lumbar erector spinae (LES), thoracic erector spinae (TES), latissimus dorsi (LD) were compared in symmetrical lifting for six different objects (0, 5, 10, 15, 20, 25 kg) under two conditions of with and without the exoskeleton. The exoskeleton significantly reduced the back muscular activity during repetitive lifting tasks. The average integrated electromyography reductions were 34.0%, 33.9% and 24.1% for LES, TES and LD respectively. The exoskeleton can reduce burden and the incidence of strain on lumbar muscles during long-term lifting work.

“…In such a back ground, a semi-endoskeleton-type waist assist AB-wear suit was developed in [8], which is actuated by two types of actuators, namely straight-fibertype artificial muscles and a balloon actuator. Also, a light weight power assist wear which uses two types of pneumatic soft actuators, namely balloon and circular actuators, was developed in [9] to reduce a physical burden caused by heavy equipment.…”

In this paper, for the purpose of practical use of the power assist suit, the overalls type power assist suit developed in our previous study was improved. The knee pad type power assist suit termed "Cool Vest" was newly developed, and verification experiments were carried out. By wearing the developed assist suit, the muscular load decreased 46% at the maximum in the case of lifting and taking down the 30kg object and decreased 43% at the maximum in the case of transferring the 20kg object by turning around. In addition, air supplying method to the artificial muscle was also improved. An air recycling system and an air generation system were proposed, and evaluation experiments were executed. As results, the number of times which can be used for assisting the transfer work increased from 5 times to 7 times by using these air supplying systems.
