An anonymous reader writes: Researchers at the University of Illinois have developed a new method of printing silver ink that could lead to dramatic decrease in the price of flexible electronics. Previous conductive silver inks used in electronics had to be printed at very high temperatures, mandating that the plastics they were printed on be able to hold up under the heat — which increased the cost of materials. The new ink lowers the energy usage needed during the process and it can be printed at 194 degrees Fahrenheit, so lower-cost, flexible plastics can be used as a base.
