Could this motion be put to work, that is, generate electricity? Scientists have noticed this wet curling effect in various polymers, but never something that could be said to perform work, such as with polypyrrole. Robert Langer at Massachusetts […]

October 20, 2003 – What started as a simple conversation between two University of Alberta engineering professors has led to the discovery of a new way to harness electricity–from flowing tap water. The […]
