New Technique to solve Smartphone Overheating!

ComScore-top-ten-smartphone-appsResearchers have developed a new temperature mapping technology for tiny devices that could help solve the problem of overheating in smart phones and computers.

The new thermal imaging technique allows engineers to “see” how the temperature changes from point to point inside the smallest electronic circuits.

The technique which is called Plasmon Energy Expansion Thermometry or PEET, which allows temperatures to be mapped in units as small as a nanometre, a unit of measure equal to one-billionth of a metre.

This breakthrough should enable engineers to design microprocessors that minimise the problem of overheating in smartphones and computers.

Modern microelectronic circuits contain billions of nanometer-scale transistors. Although each transistor generates only a tiny bit of heat as it operates, many transistors operating at once make the computer chips get very hot, which is why cellphones get warm and computers need fans to run properly.

The research team built its technique on the same physical principles behind the glass-bulb thermometer that was invented by Daniel Gabriel Fahrenheit in 1724.

PEET determines temperature in the same way by monitoring changes in density using a transmission electron microscope. The team demonstrated the technique on tiny aluminum wires that were heated on one end.
