Vodafone Power Pocket Can Put Your Body Heat to Good Use

June 24, 2013, By Sanjeev Ramachandran

How about making use of the heat from your body to charge your handheld device? Carrier Vodafone has something that would enable you to do it. The Power Pocket, from the carrier, would help you charge your cellphone battery with the heat generated your own body.

If you are still thinking what this is all about, the Vodafone Power Pocket will be available in the form of denim shorts or even a sleeping bag.

So, that means, your cellphone’s battery can be charged while you walk, dance or even sleep.


The Power Pocket has debuted at the Isle of Wright Festival, and has been made in collaboration between the British telecommunications company and the Department of Electronics and Computer Science at the University of Southampton.

Making good use of the “Seebeck Effect” from Physics, each of these smart materials are embedded with thermoelectric modules that convert temperature differences, such as between a sweaty, gyrating behind and the surrounding air-into electric voltage.

Stephen Beeby, professor of electronic systems at the University of Southampton, has been quoted as saying that the team behind this innovation has blended high-temperature material with the idea of energy harvesting. This has resulted in the Power Pocket.

Vodafone will be running trials of the technology throughout the summer. We hear, eight hours in the sleeping bag will run the battery for 24 minutes of talktime and 11 hours of standby time, assuming a the inside temperature of sleeping bag is 37 degrees F.

Likewise, strutting and shimmying in the Power Pocket will charge a smartphone for four hours.

We guess more study would go into it before the device is fully functional. The material which is flexible at present is also expected to undergo some enhancements. Whatever the shape, we find this quite innovative. What do you think?
