Stretchable Graphene Ink for Skin-Compatible Wearable Devices

Printing stretchable and skin-compatible conductors with low gauge factor and high durability is challenging. An article published in the journal Chemistry of Materials presented a skin-compatible graphene nanoplatelet (GNP)-based colloidal ink utilizing thermoplastic polyurethane (TPU) binder with tunable rheology to prepare graphene conductors with exceptional properties.
