A Magnetostrictive Energy Harvesting System for Bridge Structural Health Monitoring
Energy harvesting is a solution to feed wireless sensors for bridge structural health monitoring. Indeed, vibrations induced by traffic passing can be converted into electrical energy with suitable devices. This paper presents laboratory tests over a device based on galfenol rods, a magnetostrictive material. It is presented the general design and both mechanical and magneto-mechanical tests to verify the performance.
