Science Daily July 24, 2023 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 electronic or mechanical devices behavior or designs to improve their efficiency. Researchers in Japan explored the way a heat flux sensor consisting of certain special magnetic materials and electrodes behaves when there are complex patterns of heat flow. They etched desired patterns into the resultant film, similar to how electronic circuits are made. They designed the circuits in a particular kind of way to boost […]

Thermal nanotransistor can conduct heat away from electronic components
Nanowerk November 14, 2018 An international team of researchers (USA – Stanford University, Rice University, UC Davis, SLAC National Accelerator Laboratory, Germany) bathed a thin layer of molybdenum disulfide that is made up of layered sheets of atoms in a liquid with lots of lithium ions to make it into a transistor-like switch. When a small electrical current is applied to the system, the lithium atoms begin to infuse into the layers of the crystal, changing its heat-conducting characteristics. As the lithium concentration increases, the thermal transistor switches off. Besides enabling dynamic heat control, the team’s results provide new insights […]
