Researchers combine graphene and PEDOT:PSS to create skin-like self-healing electronic material

Researchers at the Technical University of Denmark (DTU) have developed a new electronic material that behaves very similarly to human skin and could be used in soft robotics, medicine, and health care.

The new material is flexible, tough and self-healing and so it overcomes the known weaknesses of the rigid, brittle electronic materials currently used, which can’t repair themselves. The DTU team combined the exceptional properties of graphene with the see-through polymer PEDOT: PSS, that is also electrically conductive and is, for example, used in flexible electronics and sometimes in transparent electrodes in solar cells. When the two are combined, they turn what’s usually a weak, jellylike material into a solid, flexible, self-healing electronic material.
