The discovery of nanodrumming goes back to 2008 http://pubs.acs.org/doi/abs/10.1021/nl8029866 One would think that the authors of the latest paper would have done a minimal online search and given credit to Cal Tech. After all, this phenomenon has been known for at least 9 years. That is what graduate assistants are for, right? I suppose that in defense of the overlooked precedent, they will rationalize that the Cal Tech group “merely” documented the phenomenon (discovered it) and did not convert the free vibrational energy into usable electricity… but as Robin suggests, it is not clear that they did either.
