Printable electronics and Fijitsu uses carbon nanotubes to grow Graphene

NEC has printed carbon nanotube transistors on plastic with an electron mobility of 100 cm**2/Vs

More information is here

I had previously covered work at many other labs working on improving printable electronic speed using many different methods

Fijitsu has used a forest of carbon nanotubes (MCNT) to grow graphene at low (510 degrees Celsius temperature)

The printed battery market could be larger than $2.1 billion by 2015 The forecast is from nanomarkets

They also have a market forecast for printable electronics by market application

The applications for printable electronics that they forecast are:
- Printed Displays and Signage
- Printed Lighting
- Printed Sensors
- Printed RFID
- Printed Photovoltaics
- Printed Batteries

OLED based technology dominate the forecasts in displays and lighting.

The printable electronic advances from NEC and others will be making carbon nanotubes on plastic viable for competitive or dominant printable computers.
IBM could transform the future of computers if it is successful in using DNA to build carbon nanotube based computer chips with 2-6 nanometer precision

Ovonic quantum control devices are also another possible high performance route printable computers

The Flexible printed electronics sector is growing but challenges remain
