I wish figures were hyperlinked to their larger size versions; figure 2 which is an important one to understand is unreadable; same problems with figure 5, and 7.
I did like the authors' tripartite approach the energy harvesting and utilization problem.
Surely, the approach can be extended to multiple spring mass systems; such an ensemble has the advantage of not needing fine tuning to optimize a system as long as the bounds of the dominant resonant frequencies are known.
FYI, Stephane Boisseau and Ghislain Despesse at the CEA-Leti (France) also contributed the article, entitled: "Energy harvesting, wireless sensor networks & opportunities for industrial applications".

Check back frequently. The list will be updated as new articles arrive.
@anne-francoise.pele; I appreciate the follow up and the links (& the larger versions of figures in the article!).
The need for cost-effective energy harvesting sensor nodes can not be overstated and is critical to deploying sensor networks for infrastructure monitoring.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
