| Circuits capable of functioning at temperatures greater than 350 degrees Celsius Posted: 12 Jun 2014 05:50 AM PDT Engineering researchers have designed integrated circuits that can survive at temperatures greater than 350 degrees Celsius – or roughly 660 degrees Fahrenheit. Their work will improve the functioning of processors, drivers, controllers and other analog and digital circuits used in power electronics, automobiles and aerospace equipment -- all of which must perform at high and often extreme temperatures.  |
| Lighter cars with new robotic welding method Posted: 11 Jun 2014 06:34 AM PDT A vehicle typically consists of several thousands of spot joints such as rivets, clinch joints or spot welds. They are used to bond together different parts of the vehicle. But the rivets are costly and do not have great strength. Moreover, spot joints require a certain sheet thickness to provide sufficient strength. Researchers in Sweden have now invented a welding tool that also functions as a temperature sensor.  |
| Novel process allows production of the entire circuitry on touchscreens in one step Posted: 11 Jun 2014 06:32 AM PDT When users operate their smartphones, tablets and so on, they do not give a second thought to the complicated electronics that make them work. All that concerns them is that they can happily swipe and tap away. To make the touchscreens work, they are provided on their surface with microscopically small electrical conductor tracks, which open and close circuits when touched with a finger. At the peripheries of the devices, these microscopic tracks merge into larger conductor tracks. Until now, several production stages have been needed to create them. Researchers are now presenting a novel process that allows microscopic and macroscopic conductor tracks to be produced in one step.  |
