Exoskeletons with multiple application purposes (Fox et al., 2019). (A) Exoskeleton gloves (Yun et al., 2017) can minimize the operator's force to grasp a tool and provide assistance during the execution of a task (Yurkewich et al., 2019). (B) Chairless chairs, which are wearable chairs consisting of two supports for the backs of the legs that touch the ground when wearers bend their knees to sit. (C) Exoskeletons for the shoulders (Islam et al., 2020), back, and legs can be manufactured. This can decrease human musculoskeletal pressure from repetitive, light overhead work. (D) This exoskeleton structure can contribute to and yield supporting power through the use of carbon fiber rods, which act as artificial tendons by bending when the wearer squats and springing back when they stand up. (E) Exoskeletons can deliver direct help for heavy hand tools by offloading their weight onto external support, such as a floor, via a series of linkages at hips, knees, and ankles, bypassing the wearer's body. (F) A powered exoskeleton's ability to communicate or combine different materials, such as batteries, sensors, actuators, and motors, is crucial (Ismail et al., 2019). (G) Powered exoskeletons can expand the human body by supplying and influencing energy to the arms and legs. In (H) the exoskeleton platform can be designed in an improved manner and made strong to maximize the loads that can be supported (Cho et al., 2018).
