The First Plastic Computer Processor 73

Posted by Soulskill from the won't-somebody-think-of-the-seagulls dept.
jcombel writes "There's been a lot of talk lately about developing replacements for silicon; how about a nearly-transparent film of plastic, woven into clothing or affixed directly to equipment? From the article, 'Researchers in Europe used 4,000 plastic, or organic, transistors to create the plastic microprocessor, which measures roughly two centimeters square and is built on top of flexible plastic foil. ... The processor can so far run only one simple program of 16 instructions. The commands are hardcoded into a second foil etched with plastic circuits that can be connected to the processor to "load" the program. This allows the processor to calculate a running average of an incoming signal, something that a chip involved in processing the signal from a sensor might do.'"

        No, that'd be a plastic/metal composite.

        Also, composite does not mean the same thing as a polymer. A composite is a mixture of chemically distinct materials; in a polymer, the materials have chemically combined to form polymerized molecules.

        Composite: a solid material which is composed of two or more substances having different physical characteristics and in which each substance retains its identity while contributing desirable properties to the whole

      The definition for “foil” derives from the Latin word “folium”, which means folio. The beginnings of foils go back to the 16th century, whereas it should be mentioned that at that time a little metallic glossy sheet (of gold leaf) was named by the term foil. This served as the base for enclosed gemstones. Meanwhile the term foil has been extended a lot and describes various products like for example metallic foils, plastic foils, cling film, plastic bags or transparencies. The latter

          well I do not think Webster is GOD of language anyway, and looking up the term plasic foil will yeild a billion results on the topic (besides is it not acting as a substrate for a form of crystal or gem? in this application)

          your argument can be put into the silly light by replacing foil with computer and in reverse, noun and only definition is for a machine, though for hundreds of years computer was a position in accounting, websters does not list that, so that MUST mean its complete horseshit right?

          Dude, when "OMG" and "LOL" get added to the Oxford Dictionary [vancouversun.com], it's too late to start worrying about what's "allowed".

          Let's face it, if they're just adding "rotoscope" and "suicide door" to the lexicon (both words which have been around for ever), a dictionary isn't always definitive on what words people are using in practice.

    • Nor are organic transistors "plastic"

      • How do you figure? They are "plastic" in both the noun and adjective senses.

        • I see that plastics are by definition organic, but fail to see how organic transistors are by definition plastic. My objection was to the use of plastic as a kind of simplified buzzword: yes indeed these materials fulfill the technical criteria for being considered plastics (though given the fact that it's a tiny bit of actual semiconductor material drowned in an ocean of regular ol' hydrocarbon, this isn't surprising) but to call this a "plastic computer" makes it sound like we're making it out of used bot

          • I see that plastics are by definition organic, but fail to see how organic transistors are by definition plastic.

            AFAIK, any organic polymer that is thermoplastic/thermosetting is a plastic.

            Organic: carbon-based
            Polymer: large molecule made up of repeating basic units
            Thermoplastic/thermosetting: more plastic/moldable at higher temperatures and/or solidifying or just becoming stiffer at low temperature

            They meet those criteria, so they're plastic. At least, the film used as the substrate certainly does.

    Honestly, how is this better than a silicon die in a Plastic carrier? I already can make a processor so thin that you would not feel it in a shirt, and you can waterproof it so it will survive washings. Flexing is not an issue as it's too tiny to care.

    Other than a "neat-o lookie what we did" aspect, I can not see any practical use to replace a silicon die of the same thing.

    Now I need to figure how to make legos smaller and smaller.
