An asymmetric arc-shaped vortex-inducedelectromagnetic generator for harvesting energy from low-velocity flowing water

“

Based on the theories of vortex-induced vibration and Faraday’s law of electromagnetic induction, an innovative small-scale water energy harvester with asymmetric arc-shaped beam was developed to scavenge low-velocity water energy. Benefiting from the beam’s arc-shaped structure, elasticity and asymmetry, the generator is able to scavenge energy from low-velocity flowing water. This novel small-scale generator gives the prospect of being able to power wireless sensors in remote locations.
