What If author said you that sweating mechanism of the mammals of scientists have used it to develop cooling technology in your phones? It is true that Wang and his colleagues created a coating that could convert the water to vapour from the heat given and could release this out to cool. Great machines and computers have fans to cool then whereas the smart phone lacks it.
The mammals primarily make use of the fatty acids in the body and from vapour from them or even sometimes they use water. But when it comes to our smart phones which lacks a fan or any other cooling system it is necessary to protect the Chip, battery and other internal parts and from damage. Thus it is necessary to invent this system. The mobile is coated with a covering that is water proof and there vapours are let out.
They used it over phone and have done complete test, criticize and analysed over the technology. It can be used and comes to need when there are times we can’t touch the phone just because it is steaming hot. Thus this technology seems to be high use.
