Ink jet printed flexible circuit board or can be used to manufacture large wallpaper screen

"Circuit" has left the impression of "stiff" for many people, but a research team at Michigan State University, through an ordinary ink-jet printer, has produced an extensible circuit that can be used to make "intelligent textiles" While printed circuits are not new (e.g., stamp size "Electronic Video Tags" as MIT researchers have shown them), flexible circuits are often expensive (even though the Georgia Institute of technology team has experimented with off the shelf materials on paper and PET films) This kind of extendable circuit can be printed by an ordinary ink-jet printer Even if it is stretched by hand, it will not easily cause damage to this kind of printed circuit Through different "electronic ink", it can be printed on the substrate with various components required by the circuit Chief researcher of the project Chuan Wang "We can make the manufacturing cost of flexible electronics as low as newspaper printing, and our work will soon lead to printing screens, wearable electronics, and flexible robot applications that can be easily stretched to large sizes," he said Lead researcher Chuan Wang shows that a sample "smart textile" developed by his team can also be composed of a variety of "electronic ink" circuits (including nano materials and organic compound solvents), and printers can use different "inks" to spray out complete "devices" - including elastic base materials, circuits, and OLEDs—— Although the latter two are relatively independent at present, they can be integrated in the future In the future, there may be a variety of "smart textiles" printed on extendable circuits, such as better wearable devices or wallpaper screens Details of the study have been published recently in the journal ACS Nano of the American Chemical Society Source: cnbeta.com
