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: 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: 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 ...
