Scientists are getting close to making a substance that helps a smartphone regulate its temperature by “secreting sweat”, to cool the device itself.
A team from Shanghai University in China, led by Jiao Tong, has succeeded in developing metallic material or metallic coating to cover electronic devices, and it can keep those devices cool if their temperature rises, or in short to regulate and manage their temperature, just as the human body does when its temperature rises.
According to a report published by the British newspaper “Daily Mail”, smartphones will be able to maintain their heat and cold thanks to a sweaty mineral substance, which is 3 times the thickness of human hair.
The mineral or rather a paint can release water when the electronic device heats up, then this water turns into a gas and evaporates, taking with it the extra heat, which reduces the heat of the device.
However, scientists in China, who developed this innovative method, say it is costly to use for manufacturing on a commercial scale today, but they herald the future inexpensive application.
According to scientists, the invention can be applied to all electronic devices, including portable devices such as tablets and phones.
“The development of microelectronics places great demands on effective heat management techniques because all components are tightly packed and the chips can become very hot. For example, without a system,” said Rogo Wang, who studies refrigeration engineering at Shanghai Jiao Tong University. Effective cooling, our phones can crash into the system and burn our hands if we run it for a long time or download an application that consumes a lot of energy. ”
This material may be a substitute for that used by some manufacturers, that is, “phase change materials” which are materials that release or absorb heat, such as candles and fatty acids.
When the scientists tried the developed metallic paint on the mobile phone chips and chips and compared the results with the uncoated chips, it was found that the developed paint reduced the temperature of the painted chip by 7 ° C when the device was turned on and conducted intensive work on it for 15 minutes.
