Triboelectric energy harvesting from the vibro-impact of three cantilevered beams

•Theoretical and experimental study of a new triboelectric energy harvester via vibro-impact.•Experimentally identified coefficient of restitution to model velocity-dependent impact.•The electrostatic force is weak and thus neglected, leading to decoupled equations.•A new numerical scheme for stiff...
