Energy Harvesting From Vibrations With a Nonlinear Oscillator

Energy harvesting is process of scavenging energy from environment; in context of this paper using vibrations to power autonomous systems instead of battery packs. Paper tackles ongoing fundamental problem in vibration energy harvesting: how to extract energy over wide range of frequencies. It presents experimental investigation of non-linear energy harvester with broadband frequency response. Led to EPSRC-funding for visit by Barton to Duke University and US lecture tour. In turn, this led to funded work [$160k, tinyurl.com/gen-eng-87, contact: Prof. Vakakis, University of Illinois Urbana-Champagne, US]. Paper is second most-cited paper in journal within REF period (Web of Science, 8/3/2013).
