If you think that thinner electronic devices are the future, then you are probably right. As time passes by, electronics is becoming smaller, to a scale that is now being referred as nanotechnology. But to power these devices you will probably require a similarly thin power-source. Thanks to Stanford University, researchers there identified that Single Walled Carbon Nanotubes (SWNTs) can be printed on paper, and then treated with polyvinylidene fluoride to create ultra-thin super-capacitors, that will be able to store energy.
The source of energy will also be very stable. “The device also showed an excellent cycling stability, with very little loss of capacitance after 2500 cycles.” In short, these paper-capacitors are the future. We have seen significant developments in nanotechnology in the last ten years. But in order to make ultra-thin computers (a.k.a. computers of the future) a similarly sized power supply has always been necessary. And it sure looks like we are heading to the right direction!
