Korean researchers fabricated a stretchable, transparent graphene-based transistor. They say that the new to transistor overcomes some of the problems faced by transistors made of conventional semiconductor materials - which simply cannot be made stretchable and transparent on substrates such as rubber slabs or balloons.

The graphene based transistors could be stretched up to 5% for 1,000 times and still maintain their good electrical properties. In one experiment, the researchers fabricated the graphene transistors on a rubber balloon and measured its electrical properties as they inflated the balloon. When stretched more than 5%, the electrical properties began to degrade, due partly to microcracks and other defects in the graphene films.
