Transparent electrodes in today’s devices are made of indium tin oxide films. These films are typically 90% transparent and have a resistance of less than 100 ohms. But they are expensive and brittle. Graphene could be a stronger, lower-cost, and more bendable alternative. However, the resistance of a typical graphene sheet is usually more than 500 ohms. By integrating metal nanowires into conventionally grown graphene films, researchers lowered the films’ resistance. The resulting material is 94% transparent and has a resistance of 64 ohms."
If you push the "extra ice" button on the soft drink vending machine, you won't
get any ice. If you push the "no ice" button, you'll get ice, but no cup.
