Piezoelectric nanowires could lead to blood-powered iPods, cellphones

You know what'll be awesome? Actual end products resulting from this presumably nonstop research on piezoelectric nanowires. Yet again we're hearing of a new group of researchers that have figured out a way to harness electricity from life's simplest things: walking, a heart beating or even the flowing of blood. Put simply, the gurus have discovered how to use zinc oxide nanowires in order to generate an electric current when "subjected to mechanical stress." The difference here, however, is that these critters could actually be implanted under the skin, though the scientists have made quite clear that there isn't a timetable for commercial production. In other words: yawn.
