Silicon Circuits That Bend and Stretch 73

Posted by Soulskill from the one-size-fits-all dept.
Matty the Monkey brings us a story from the BBC about silicon chips which can bend, flex, and even stretch. Researchers have developed a method to create circuits just 1.5 microns thick, which can then be bonded to a type of rubber to allow a great degree of flexibility. Scientists and companies see uses for these circuits in products ranging from "electronic paper" to form-fitting sensor devices to advanced brain implants. From BBC News: "To create the foldable chips, these circuit layers are deposited on a polymer substrate which is bonded in turn to a temporary silicon base. Following the deposition of the circuits, the silicon base is discarded to reveal delicate slivers of circuitry held in plastic. These are then bonded to a piece of pre-strained rubber. When the strain is removed, the rubber snaps back into shape, causing the circuits on the surface to wrinkle accordingly."

      Yep. That's right! People wear free shirts and give away free advertisement space. Imagine the annoyance/positive marketing impact with animated shirts!

        Great! People already wear shirts with huge logos all over them, and they seem to have a strange attraction to animated pictures. Can you imagine the consequences of having these in our clothing? Walking billboards, suggestive animated pictures, and several combinations of them. I'll make sure to charge for my add space.

      The chips are already waterproof, as are the PCBs. The problem is the connections from chip to PCB, and to things off the PCB -- power connectors, memory sockets, etc. Keyboards and such are also a problem, not to mention CD drives or anything else with exposed moving parts.

      A waterproof laptop would be very nice, but this isn't all that relevant. Besides, I doubt we're talking about high-performance chips here anyway.

    Many of the developments in display technology and "printed" electronics are leading to a future that I've been thinking about. It's almost a certainty, actually.

    Imagine a world where every flat surface (that's not a window) is a electronic display. Probably not in homes right away; amusement parks / Las Vegas would be the first to implement it, followed by malls and other areas where large numbers of people visit.

    Over time, the displays would spread to cover almost every surface. It's tempting to imagine being able to change the wallpaper in your living room as easily as you can change the wallpaper on your computer desktop.

    But what it'll more likely be is advertising everywhere you look. Like Minority Report, but much more so. With low power displays and cheaply printed electronics - it'll be a quite different world.

    The very first applications will be ones where small display size and high cost are justified. Like the labels on packages facing retail consumers. Minority Report got this one wrong; the package would put on it's "song and dance" for potential customers. Once it was purchased and taken home it'd probably quiet down via programming (or dead batteries).

    Think about a classroom where the "blackboard" is an electronic display; not just the instructor's scribblings but video, too. How about a large screen TV you unroll and stick to your living room wall?

    The future will be made of inventions like this one. How that future evolves will be determined by who wants to spend the money to develop / implement it. I can hardly wait until I can chuck Nerf balls at the guys running around on my walls...

      Also, covering everything in displays would come at a huge cost. Even if the displays are cheap, they'll inevitably use electricity. I don't look forward to having a power bill for my wallpaper.

      Why would packaging quiet down once it's purchased? If it gets to that point, it will have some cheap sensor that determines how much is left and notify you that you need to go out and purchase more of the product. Hell, your house will have a built in computer that builds a shopping list for you and prints it out, or sends it to your mobile device so you can shop. Better yet, it will (upon your request) send it directly to the store, and someone will deliver the goods to your home.

Maybe a whole new section of flexible MEMS like sensors will be released based on convention etching as well ?
