Vodafone court prototype mobile phone charging technology on the Isle of Wight Festival this weekend. Developed by the University of Southampton, electronics and computer science institute uses the Power-pocket the Seebeck effect, the use of the temperature difference between the human body and its environment, an electrical current that can be used to recharge a smartphone to generate. Vodafone has the bag in a sleeping bag (called Recharge) and a pair of shorts (shorts called power) to test the woven technology.
“We basically below Print pairs of so-called” thermocouples, ‘”says the University of Southmapton Professor of Electronic Systems, Steve Beeby.” You print a lot of them to make down and close up to a thermoelectric module. “This product is the result of decades of research in printed, smart, and thermoelectric materials, Beeby explains in a press release.
Beeby says that an eight-hour sleep will provide 24 minutes of talk time or 11 hours standby time (although this is clearly dependent on the phone). “That’s assuming the inside of the sleeping bag is 37 degrees,” he says in the press release. But what is the appropriate ambient temperature for this service needed? “The calculations are based on an ambient temperature of 10 ° C and 17 ° C but can be lost on other materials that the thermoelectric module provides 10 ° C,” says Beeby Gizmag. The actual current and voltage have not been calculated, but was based on the Seebeck coefficient, he said.
The material is still under development, and there is more work as far as durability goes to do. However Beeby estimates that, what goes with similar research elsewhere (see power felt, for example), thermoelectric materials will be woven into clothing as a matter of course over the next decade.
How Beeby notes, this is not a unique idea. In fact, Vodafone competitor orange pulled a similar stunt with thermoelectric rubber boots for Glastonbury Festival a few years ago.
