"conductivity of more than 1,000 siemens per centimeter, that is able to be processed using simple industrial printing methods and solvents... Industrially, the biggest benefit to this in my mind is that if you want a 20-nanometer film, you can do that. Or if you want a one-micron film—which is 500 times thicker—you can do that, too. You really have a lot more control... electronic devices onto skin and into implantable devices, where mechanical flexibility is very important"
