A group of Korean scientists demonstrated a novel concept of graphene transistors on Scotch tape for use in ubiquitous electronic systems. Unlike common plastic substrates, the Scotch tape substrate is easily attached onto various objects such as banknotes, curved surfaces, and human skin, which implies potential applications wherein electronics can be placed in any desired position. Also, the Scotch tape serves as an agreeable substrate for flexible/foldable electronics that can be significantly bent, or even crumpled.
