Future Electronic Components Printed Like Newspapers

Last Update Time: 2018-12-24 17:56:55

A new manufacturing technique uses a process similar to newspaper printing to create smoother and more flexible metals for ultrafast electronic components. Rolling laser-induced superplasticity, a new manufacturing method that prints metals at the nanoscale, making electronic devices ultrafast.

 

A low-cost process developed by researchers at Purdue University that combines tools that have been used in the industry to manufacture metals on a large scale, but uses roller speed and precision to wind up newspaper printing to eliminate several manufacturing obstacles of manufacturing electronics faster.

 

Mobile phones, laptops, tablets, and many other electronic devices rely on internal metal circuitry to process information at high speed. Current metal fabrication techniques tend to make these circuits by passing fine droplets of metal droplets through a circuit-shaped stencil mask, somewhat like spraying graffiti on a wall.

“Unfortunately, this manufacturing technology produces metal circuits with rough surfaces that cause our electronics to heat and drain the battery faster,” said Ramses Martinez, assistant professor of industrial engineering and biomedical engineering. Future ultrafast devices will also require smaller metal parts, which require higher resolution to make them on these nanoscales.

 

“The metal that forms smaller and smaller shapes requires higher and higher definition molds until you reach nanometer size,” Martinez said. Recent advances in the addition of nanotechnology require us to model the dimensions of metals, even smaller than the grains they make. It's like that a rustling castle is smaller than sand. ”

 

This so-called "forming limit" hinders the ability to fabricate materials at high speeds at nanoscale resolution. Researchers at Purdue University have solved these two problems—roughness and low resolution—to create a smooth metal circuit on the nanometer scale using a new mass production method using traditional carbon dioxide lasers. This is already common for industrial cutting and EN. “Printing tiny metal parts like newspapers makes them smoother. Martinez says this allows the current to run better while reducing the risk of overheating.

 

This manufacturing method is called roll-to-roll laser-induced superplasticity, which uses a stamp that scrolls at high speed like a newspaper. This technique can induce "superelastic" behavior of different metals by applying a high-energy laser beam in a short period of time, which allows the metal to flow into the nanoscale features of the roll - bypassing the forming limit.

 

Martinez said: "In the future, the roll-to-roll manufacturing of equipment using our technology enables the fabrication of nano-structured touch screens capable of interacting with light and the generation of 3D images, as well as the cost-effective manufacture of biosensors."
