Purdue University researchers have developed roll-to-roll laser-induced superplasticity, a manufacturing technique that can make electronics faster than conventional methods.
The process is similar to newspaper printing, but it can form smoother and more flexible metals that are needed to make ultrafast electronic devices.
The method uses a rolling stamp such as those used to print newspapers at high speed, and it can briefly induce "superelastic" behavior in different metals by applying high-energy laser shots, enabling the metal to flow into the nanoscale features of the rolling stamp.
Purdue's Ramses Martinez says this process could enable the creation of touchscreens covered with nanostructures that can interact with light and generate three-dimensional images.
