Don’t Waste Your Breath, Because You Can Use It to Charge Up Your Gadgets

 |  |  |  |  October 7, 2011

This isn’t the first time we’ve heard of a device that can generate electricity from human breathing. Jmengel’s nifty little device that can generate charges via continuous breathing serves as a bit of a preview to this device that researchers from the University of Wisconsin-Madison have now developed.

Breath ChargerThe charger is actually a small piezoelectric microbelt that has the capacity to generate tiny amounts of electricity. The researchers behind the study, Xudong Wang, Chengliang Sun and Jian Shi, explain that the device generates a charge when it vibrates because of exposure to moving air – or someone’s breath. The microbelt can hold and deliver enough energy to recharge medical devices like blood glucose monitors and pacemakers, which is great news, because the batteries for these devices often have to replaced via surgery.

The device can be implanted into the human nose. So it doesn’t make use of the breath coming from your mouth per se, although if you’re a huge talker (or a mouth breather), then that’s a whole different story.
