Body heat to power your wearable gadgets

RATE THIS! +36
Posted in Hardware on 12th Apr, 2014 02:34 AM by AlexMuller

As the attention turns towards wearable devices like Google Glass and smartwatches, how to ensure power supply in a stable and reliable manner is one of the most critical issues facing the developers. What about a light, tiny generator that can produce electricity from the heat emanating from the human body? 

 
Possible. A team of researchers have proposed a solution to this problem by developing a glass fabric-based thermoelectric (TE) generator that is extremely light and flexible and produces electricity from the heat of the human body. In fact, it is so flexible that the allowable bending radius of the generator is as low as 20mm. 
 
"There are no changes in performance even if the generator bends upward and downward for up to 120 cycles," claimed Byung Jin Cho, a professor of electrical engineering at KAIST (formerly also known as Korea Advanced Institute of Science and Technology) in South Korea. 
 
The team came up with a new concept and design technique to build a flexible TE generator that minimises thermal energy loss but maximises power output.

This looks very interesting. Using body heat as a source of energy is great idea and particularly suitable for wearables - that could be the way to make them popular Reply

Yes, thermoelectric (TE) generators are good idea. In particular TE generators that have been developed based organic materials. The organic-based TE generators use polymers that are highly flexible and compatible with human skin, ideal for wearable electronics.

I think that this great idea ant just foe wearables. This flexible, light and high-performance TE generator could have further applications in scale-up systems such as automobiles, factories, aircrafts, and vessels where we see abundant thermal energy being waste! Reply

Another good think is that the fuel sugar solution is neither explosive nor flammable and has a high energy storage density. Reply

This is exactly what rapidly growing, portable electronics need: high-energy-density, green, safe batteries. Highly desirable! Reply

Energy demands are getting bigger all the time and we could be running out of resources - this TE generator could be a good solution at least for some devices - promising Reply

The energy resources are the big issue and there are many attempts towards some solution. It was reported that researches found a catalyst, cobalt oxide nanoparticles, that can quickly generate hydrogen from water using sunlight, potentially creating a clean and renewable source of energy.

The experiment has potential as a source of renewable fuel, but at a solar-to-hydrogen efficiency rate of around 5 percent, the conversion rate is still too low to be commercially viable. The same problem as with cellulose Reply

Recently there was a serious attempt to reintroduce nuclear energy at a large scale. This is a proposition that urges a crucial discussion on the role of nuclear power in fighting climate change.

The "nuclear" vs "renewable debate is open and different countries are adopting different policies. I believe we need both Reply
