摘要
In this study, energy harvesting devices using Wiegand-effect transducer is investigated through integration with linear positioning measurement system. With the device, energy can be harvested due to the changes of magnetic polarities from linear position measurement system. Using numerical finite element method, the energy harvesting module is parametrically investigated to offer the optimal design in the magnetic guide that directs the dynamic magnetic field into the Wiegand transducer. From experiments, the influence of parameters such as geometry, speed and gap size has been validated to offer optimal design composition to provide the highest energy output from the system.
