Scientists in the Republic of Korea have sandwiched an organic piezoelectric material – poly(vinylidene fluoride trifluoroethylene) [P(VDF-TrFE)] – between two graphene electrodes to make a fully flexible, rollable, stretchable, foldable and twistable nanogenerator.
The output voltage of the nanogenerator is up to 30 times that of a rigid nanogenerator when exposed to the same input sound waves and 8 times higher in the same air flow.
The team says that stretchable power generators could easily be transferred to fabrics, including clothes and flags for example, allowing them to harness energy from people’s movement or the wind.
