Cellulose makes up about one-third of all organic biomass and when layered and wetted using a technology known as electro-microfluidics will produce electronic switches and gates much like those on a silicon-based circuit board. Among the advantages of a paper based electronic array are displays with that look and feel like real paper and can be folded or rolled, are easily carried and then discarded.
“Circuits On Cellulose – Paper Electronics Could Pave The Way To A New Generation Of Cheap, Flexible Gadgets” in the February issue of IEEE Spectrum provides just an overview of upcoming developments and commercial possibilities. “Developments underway using cellulose are interesting and surprising in their variety,” comments Steckl. “The number of uses is proving extraordinary.”
Nanotechnology using paper mediums may be the first commercial products to reach consumers as advances in biomedical science produce diagnostic tools placed on paper that when put in contact with saliva, urine, blood or sweat will immediately tell if a person has a virus, had bad food, major disease or a hangover. Best part – the cost is only a few cents and when the test is done, just burn the strip. These items could become a staple for doctor’s offices, third world clinics and individuals for direct use.
This abundant and simple material offers many advantages and generally low cost for the electronics of the future.
