From: Nanostructured versus flat compact electrode for triboelectric nanogenerators at high humidity
Measured single pulse results and the charge transfer of TENG in different morphology as a function of relative humidity. (a) The current at a pressing-releasing mode under a single tap. (b) The induced charge based on the integration highlight area under releasing mode. The charge transfer of TENG as a function of relative humidity at: (c) Ti foil, (d) TiO2 thin film, (e) TiO2 nanoparticulate film, and (f) TiO2 nanotube film.
