Abstract
A triboelectric device in which electrical charges are obtained by a rolling process between two rigid dielectric surfaces of appropriate materials, one of which may be planar. There exists therein no injection of electrical charges originating from outside. The separation of the charges with the concomitant generation of electrical potentials is effected by the movement of the parts by triboelectrification. Such devices are useful in the construction of electrostatic generators for teaching, research or industry and as an essential supply for fixed or portable ignition devices for boilers, cookers and gas burners.

A rolling-type triboelectric generator for obtaining electromotive forces without using external charge sources, comprising:
- a plurality of wide active components having external surfaces, at least one of said active components having an external surface which is mutually rollable on an external surface of another of said active components;
- a plurality of wide electrical charge collecting components having electrically conducting surfaces, said electrically conducting surfaces of said charge collecting components being arranged for mutual rolling on wide external surfaces of respective active components;
- said active components comprising respective materials occupying different positions in the triboelectric series, and serving as triboelectrification generators of positive and negative electrical charges in equal quantity separated in the components of different materials and having unequal electrostatic potentials;
- and
- said collecting components comprising at least two collecting bodies having solid electrically conducting portions at least at the surfaces thereof which are arranged for said mutual rolling on said respective active components;
- and
- means coupled to said collecting components for transferring electrical charges generated by said mutual rolling from solid electrically conducting portions at the surfaces of said at least two collecting bodies to external terminals.
