I think to print LEDs or other devices directly on paper using chemical methods will have some positive impacts on technology. Because the method is inexpensive, easy, environment friendly and the devices can be fabricated on large area.
There had been many like this. For example year 2005 printed integrated electronics circuits was exhibited at the Plastics Electronics trade fair in Frankfurt. So many researches are made on this line but finally when it comes to cost of production they do not compete.
thank you Anne-Francoise, cool technology...I wonder how long before possible real application, 5 years? 10 years?...Gul: would you be interested in presenting your research at emerging technology symposium in Whistler in 2013? details at www.cmoset.com, Kris
Also of interest: In one of the thesis articles, published in Springer’s Journal of Material Science, Gul Amin demonstrates how it is possible to grow nanorods on paper, blow them off the surface using ultrasound and collect them in the form of a powder.
This powder can then be used to print the nanorods of zinc oxide, and thus LEDs, on paper or plastic in a normal printing press.
That method also has patents pending.
