Touchscreen more and more more thin and foldable News

The touchscreen of the future, probably, you will be able to roll up and keep in your pocket or under your arm, just as if it were a daily paper. To afford it is a new technology just developed by experts from Rmit University, who have managed to zoom out (further) the thin film used in the screens of smartphones and tablets, making it impalpable and soft as a sheet of paper, to be precise. The details of the discovery were published in the journal Nature Electronics.

The “sheets touch of a new generation, say the authors of the research, are compatible with the technology already existing, and could even be “printed” with a technique similar to that used for the paper. To create the material, scientists have tried to improve on a compound that already exists, the indium-tin-oxide, highly conductive but also very fragile: “Basically,” explains Torben Taeneke , at the head of the team that conducted the research, “we have taken an old material and we have developed it ‘from the inside’ to create a version of thinner and more flexible: not only can you fold it and torcerlo without damaging it, but you can produce a much more efficient way and economical way compared to what happens with normal touch”. The improvements do not end here: the shrinking of the material (which, in fact, has been transformed from tri - to bi-dimensional) has also made it more transparent, which means they let in more light and therefore requires less lighting – that, in cascade, imply a saving of the consumption of the battery, estimated in 10%.

What do you mean “you manage to produce so much more efficient and cost-effective”? It is soon said: the scientists argue that in order to create the new touchscreen just a piece of equipment very cheap. “Our approach,” continues Daeneke, “does not require expensive tools or specialized. You can replicate in the home kitchen, using equipment that you can buy in any store of do it yourself.” The recipe is this: the oxide of iridium-tin is heated to 200 °C, the temperature at which it becomes liquid, and then is poured onto a surface where it is deposited, creating sheets of very thin, whose microscopic structure is different from that of the material in the solid state. In the sense that it has optical and mechanical properties very best, as we said above: more flexibility, less absorption of light, the more electrical conductivity. Scientists have created and successfully tested a functioning prototype and are now awaiting approval of the patent application to bring the product to market.
