This overview of research resulting from not only his own work but that of his many colleagues around the world offers insight into a myriad of potential unexpected products made on or from paper that promise to be less expensive and easier to use than those currently made using more sophisticated (and expensive) technology. “Since starting this article two years ago, it has gone through more than a dozen revisions to accommodate the many advances being made in the field around the world,” states Steckl.
Cellulose is a natural material that in the various forms of paper has been around for ages and, as our technology develops further, is demonstrating even more uses. The most remarkable of which may be as a substitute for silicon in electronic substrates – particularly for electronic displays. And the best part is that cellulose is readily available, renewable, biodegradable, and also combustible. Electronics built on paper can be landfilled or just compressed and burned as fuel in a power plant.

“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.
