Ever dreamt of a paper world with all your electronics made out of paper? You don’t need to be an origami fan to dream about things like that anymore. Paper electronics might just pop up in the future, thanks to the researches at Stanford University, who’ve come up with a technology to make this dream into a reality. Paper super capacitors have been stumbled upon by printing carbon nanotubes onto paper. These can be printed onto everything and involves the coating of both sides of a piece of paper with polyvinylidene fluoride (PVDF).
The treated paper bonds to the super capacitor, just like ink and paper bonding and works efficiently, with minimal capacitance loss after 2500 charge-discharge cycles. If all goes well, the future might have electronic devices made of paper, that we can dispose of easily when out of use and recycle, keeping away the trouble of recycling e-waste that we face today.
"Light Emitting Wallpaper to Replace Light Bulbs in 2012 Light Emitting Wallpaper to Replace Light Bulbs in 2012 A company developing ultra-efficient organic LED lighting technology has been awarded a £454k grant by the Carbon Trust. The OLED materials, being pioneered by LOMOX Ltd, have a wide variety of potential applications and when coated onto a film could be used to cover walls creating a light-emitting wallpaper which replaces the need for traditional light bulbs. As well as being flexible, OLED film will require a very low operating voltage (between 3 to 5 volts) so it can be powered by solar panels and batteries making it ideal for applications where mains power is not available such as roadside traffic warning signs."
