Transparent Transistors Printed On Paper 51

MTorrice writes "To make light-weight, inexpensive electronics using renewable materials, scientists have turned to a technology that is almost 2,000 years old: paper. Researchers fabricated organic transistors on a transparent, exceptionally smooth type of paper called nanopaper. This material has cellulose fibers that are only 10 nm in diameter. The nanopaper transistors are about 84% transparent, and their performance decreases only slightly when bent."

    I've read the fine article, and it might not be immediately clear from the summary that the breakthrough here is not the transistor per se - the important step was in using the "nanopaper" (which is tech that is in fact NOT 2KA old).

    And while the nanopaper may be biodegradable, I am wondering about the carbon nanotubes they are printing on top (as conductors). While the toxicity of carbon nanotubes is still being studied, there are good indications that they might behave similar to asbestos fibres. So not something you would necessarily want to throw on your compost heap.
