Proximity Enhanced Energy Harvesting of Multi-Axis Motion (PROXEE)
Date du début: 1 janv. 2014, Date de fin: 31 déc. 2015 PROJET  TERMINÉ 

Proximity Enhanced Energy harvesting of multi-axis motion (ProxEE) is a proposal to design, model, fabricate and test a class of inertial micro energy harvesters that convert multidimensional and non-periodic human motion into electrical energy for powering body worn and medical devices. The harvester uses a spring-less spherical magnetic proof mass to capture kinetic energy from the user, after which an array of transducer ‘cells’ employing a novel actuation method are used to convert the mechanical energy into electricity. The contactless actuation mechanism uses magnetic attraction between the proof mass and a magnetic fluid to induce an aspect change in a variable capacitor thereby allowing the coupled energy to be transduced using electrostatic means. A hydraulic amplification scheme is utilized to produce a mechanical advantage and to increase the force in the electrostatic transducer. The mobility proposed in this project is for the fellow, an expert in the field of energy harvesting and microsystems technology, to expand his skill set and research portfolio while working on a novel project at the University of Freiburg Department of Microsystems (IMTEK) in Germany. This project couples together the fellow’s expertise in developing low-frequency wide bandwidth motional energy harvesters with the host’s mastery in the development of microsystems technologies, materials testing, and mechanical design. This project will have a strong impact on the European Research Area (ERA) through the innovative project and associated knowledge creation, focused knowledge transfer and a new international collaboration, training of students, and outreach.
