Abstract: This paper investigates a frequencytunable nonlinear electromagnetic energy harvester. The electromagnetic harvester mainly consists of permanent magnets supported on the base to provide a magnetic field, and electrical ...

Abstract: In this study, a harvesting device embedded into a suspended backpack was developed to harness part of a human's biomechanical energy and reduce dynamic force of the backpack on the carrier. The harvester utilized a spring ...

Abstract: Spiral spring is widely used in mechanisms, such as mechanical watch movements and clocks where the spiral spring is used for timekeeping. According to literature, there are only a few studies on spiral springs. In this ...

Abstract: Backpacks are essential for travel but carrying a load during a long journey can easily cause muscle fatigue and joint injuries. Previous studies have suggested that suspended backpacks can effectively reduce the energy ...

Abstract: Invented more than 200 years ago, the automatic winding device of mechanical watch movement is one of the most successful energy harvesting devices. It harvests the kinematical energy from body ...

Abstract: Strokes caused by cerebrovascular diseases often result in severe damage to locomotion, movement, and cognitive functions. Rehabilitation is an effective way to regain locomotion ability in daily life. However, there are ...

Abstract: The purpose of this work is to investigate the efficiency of wearable assistive devices under different load-carriage walking. We designed an experimental platform with a lightweight ankle-assisted robot. Eight subjects ...

Abstract: Upper limb paralysis and movement disorders resulting from neurologic injuries can be treated with an upper limb exoskeleton robot that assists with movement retraining. Cable-driven exoskeletons have been widely studied ...
