Wearable technologies are driving current research efforts to self-powered electronics for which novel high-performance materials such as graphene and low-cost fabrication processes are highly sought. We demonstrate the integration of high-quality graphene films obtained from scalable water processing approaches in emerging applications for flexible and wearable electronics. We developed a novel method for the assembly of shear exfoliated graphene in water, comprising a direct treansfer process assisted by isopropyl alcohol evaporation. We demonstrate that graphene films can be easily transferred to any target substrate such as paper, flexible polymeric sheets and fibres, glass and Si substrates. By combining graphene as electrode and polydimethlysiloxane as active layer we demonstrate for the first time a flexible and transparent triboelectric nanogeneragor for haversting energy. Our results constitute a new step towards the realization of energy harvesting devices that could be integrated with a wide range of wearable and flexible technologies and opens new possibilities for the use of triboelectric nanogenerators in many applications such as electronic skin and wearable electronics.
