In the present work a single layer triboelectric generator (TEG) composed of Kapton film against Polytetrafluoroethylene PTFE thin layer investigated under different conditions to obtain the effect of contact mode, frequency, surface properties and electrode material on generated electricity as a result of friction between layers.

Triboelectrification refers to the process of generating electric power from mechanical activity especially frictional contact of two different materials. All materials generate surface static charge after contact with each other, for conductors; static charge rapidly disappears from the surface internally. Not yet for insulating materials as polymer, textiles, wood, and paper provide the remaining surface charge that can be used as a useful source of energy.
