Hamster-Powered Generator? Why Not

They are manufacturing generators out of piezoelectric nanowires. The latest model in fact consists of zinc-oxide nanowires connected to one another and mounted on a flexible plastic surface. This nanogenerator aims to collect different kinds of biomechanical energy. They did an experiment by placing a small jacket on the hamster’s body. As the hamster runs in the treadmill and scratches itself, an energy produced and harvested by the generator.
