Researchers Design Conductive Tracks That Can Be Stretched Up To Four Times Its Length
Researchers from the Ecole Polytechnique Fédérale de Lausanne (EPFL) have developed a conductive malleable track that can be stretched up to 4 times in any direction. In general, the commercial conductive tracks are hard printed on the board, but with such a technology these conductive adhesives can be stretched up to a million times without reaching the ultimate rupture point.
The EPFL spin off product consists of a rubber like metallic constituent and a partially liquid filled film which will eventually design a variety of applications that might revolutionize emerging technologies. The new product can be found to be very useful in electronics circuit design. Also, its flexible nature makes it a very desirable product for artificial skin fabrication.
Thermal evaporation of gallium on bare and gold coated PDMS substrates
By manipulating the high surface tension of these metallic liquids, scientist could produce a reliable nano-sized thick and narrow structure that would aid current electrical and electronic technologies. Owing to the electrical properties of Gallium, the chosen Gold-Gallium alloy gives a persistent performance in terms of sustainability and conductivity. The Gold layers help Gallium to maintain its homogeneity and retain its proportions, when it comes in touch with the base and polymer.
As claimed by the team, their research product will provide the key support to the elastic approach on electronic circuits. With growing industries and prospects, utilizing the unconventional properties of natural elements might help in opening up new interesting fields. The research was reported on the 29thFebruary issue of the Advanced Materials journal.
