Can Human Blood energize iPods and Cellphones?

This can be a possibility as the this body movement, beating of a human heart or simply the blood flow can be converted into electricity using nanowires made up of zinc oxide.

Zinc-oxide nanowires can conduct electricity since they are piezoelectric which can generate electric current when exposed to mechanical stress. As Georgia Institute of Technology lead researcher and professor Zhong Lin Wang said, “This research will have a major impact on defense technology, environmental monitoring, biomedical sciences and even personal electronics”. This same team conducting various studies with regards to nanotechnology and it’s much wider application among electronics and gadgets.
