    Bad breath has never been more than a disgusting nuisance before. Now, Researchers at the University of Wisconsin-Madison have fashioned into being a device that uses human breath to generate electricity! Engineers Xudong Wang, Chengliang Sun and Jian Shi developed a material known as polyvinylidene fluoride (PVDF) that produces an electric charge whenever low-speed airflow passes over it, causing it to vibrate. The vibrations aide in electricity generation by creating piezoelectricity.

    Now don’t go expecting this little device to generate power for your home. The microwatts it does generate however could be easily used to power up devices implanted in the human body!
