Design and optimisation of a footfall energy harvesting system (2014)
Journal Article
Gilbert, J. M., & Balouchi, F. (2014). Design and optimisation of a footfall energy harvesting system. Journal of Intelligent Material Systems and Structures, 25(14), 1746-1756. https://doi.org/10.1177/1045389X14523853

The scavenging of electrical energy from normal human activity has a number of attractions, and footfall energy is seen as one of the most attractive sources. However, footfall motion is characterised by relatively large forces and low velocities, an... Read More about Design and optimisation of a footfall energy harvesting system.
