Miniaturised electromagnetic generators for portable applications

Dr. Maeve Duffy, Damien Carroll

With the advent of wearable electronics, demands of power sources for portable electronic equipment are ever-increasing. Requirements include increased functionality and decreased size, with power sources (e.g. batteries) providing at least the same lifetime. In this project, the possibility of capturing some of the energy expended by a person while walking / running and converting it into electrical energy will be investigated. In this way, demands of conventional power sources will be reduced. The design of power generators for integration in a person's clothing / shoes will be investigated for this purpose. Circuit models will be applied to predict maximum voltage & power levels produced during walking. Analytic and Finite Element Analysis (FEA) models will be applied to design generator winding and core structures. The main outcome of the work will be specification of the power level available from electromagnetic generators designed for integration in the shoes.

Start date: 1st of October 2002. This project is currently active.

Project collaborators: IRCSET Embark Initiative
