Researchers from the University of Michigan, Massachusetts Institute of Technology (MIT) and Honeywell International, Inc. have developed microscale vacuum pumps that could lead to tiny, more efficient cooling systems for faster processors in smartphones. Developed as part of DARPA’s Chip-Scale Vacuum Micro Pumps (CSVMP) program, the new microscale vacuum pumps are intended … [Read more...]
New Method Uses Paper and Inkjet Printer to Create More Heat-Tolerant Carbon Electronics
Researchers at the Max Planck Institute of Colloids and Interfaces in Potsdam-Golm, Germany have developed a simpler and more cost-efficient means of creating microchips for electronics applications using paper and a conventional inkjet printer. The use of flexible, cost-efficient microchips as a replacement for silicon chips, which are more expensive and difficult to make, is … [Read more...]
New Tool Could Provide Better Understanding, Method for More Efficient Thermal Transfer
Researchers from the University of Toronto Engineering in Canada, with assistance from colleagues from Carnegie Mellon University in Pennsylvania, have published new insights into how materials used in electronics transfer heat, which could lead to smaller, more powerful electronic devices capable of more efficient thermal management. According to Dan Sellan and Professor … [Read more...]
Researchers Demonstrate Thermal Invisibility Cloak with Potential for More Effective Heat Management
In recent years, scientists have developed the ability to manipulate light around an object through the use of man-made “metamaterials,” rendering the object seemingly invisible. Now, researchers from the Karlsruhe Institute of Technology (KIT) in Germany have demonstrated the similar ability to manipulate the flow of heat across a sheet of metal to hide a defect in the … [Read more...]
New Method Combines Gallium Nitride and Diamond for Better Thermal Management of Amplifiers
A demonstration of what is considered to be the first-ever gallium nitride (GaN)-on-diamond high electron mobility transistor could significantly reduce thermal resistance and increase RF performance in monolithic microwave integrated circuit (MMIC) power amplifiers, DARPA said in a statement. While MMIC power amplifiers equipped with gallium nitride transistors hold the … [Read more...]
