Excess heat from electronic or mechanical devices is a sign or cause of inefficient performance. In many cases, embedded sensors to monitor the flow of heat could help engineers alter device behavior ...

Why heat flux (flow) is an important thermal parameter. How researchers have developed an innovative heat-flux sensor. Details on the performance of this sensor in flat and curved situations. We know ...

The bio-inspired metasurfaces act like a real cloud, enabling daytime cooling, heating and thermal camouflage in a single solution. How does a cloud stay cool under direct sunlight –– or seem to ...

This coolant is compressed, which significantly increases its temperature, and is then moved to the designated heat location, where the heat is extracted by either passing air or water over the hot ...

The ability to sense heat protects the body from burns and injury. But how the body actually feels temperature has remained an elusive mystery. Now, Northwestern University researchers have captured a ...
