 Researchers print see-through  electronics onto PAPER

 

Scientists have used one of the simplest,  ordinary materials to create the latest and flattest in electronics – paper.

Researchers at the University of Maryland have taken the first step towards green, flexible electronics by  printing transparent electronics onto ‘nanopaper,’ created from wood pulp  treated with enzymes and mechanically beaten.

They developed the transistor on the surface  of the nanopaper by printing three different inks on it.

In their paper Highly Transparent and  Flexible Nanopaper Transistor published on January 25, the researchers explained  that the transistor had ‘unique  properties, such as flexibility, cost efficiency, lightweight and renewability’ and that the field of ‘green electronics’  was becoming an emerging field of research with commercial interest.

The transistor is 84 per cent transparent and  malleable, allowing it to still perform when slightly bent. The nanopaper is It  is thin enough to be cut or folded leading the way for foldable  electronics.

Researcher Liangbing Hu, quoted by Extreme  Tech, said: ‘It’s as flat as plastic.’

The report wrote: ‘The device configuration  can be applied to many other  semiconductor materials toward flexible green  electronics.’

Printed on the nanopaper was a layer of  carbon nanotubes, a dielectric ink, a semiconducting ink and another layer of  nanotubes.

Carbon nanotubes are single atomic sheets of  carbon rolled up into a tube and are 10,000 times smaller than a strand of human  hair.

Their next challenge for researchers will be  to devise a way to print the nanopaper on a commercial, mass production  scale.

The breakthrough has come after researchers  at IBM revealed a new technique that could one day replace silicon in computer  chips, making them dramatically smaller and faster.

For the first time, the team revealed they  have created a carbon ‘chip’ with more than ten thousand working transistors  made of nano-sized tubes of carbon, which have been precisely placed and tested  in a single.
