Researchers at Georgia Institute of Technology have discovered a way to produce electricity from random mechanical motion using triboelectric nanogenerators. These are devices fabricated from flexible polymeric materials with a high degree of transparency. Rubbing the surface of these devices can generate alternating current from friction. The research was published in the June issue of […]
