Assignee: NATIONAL UNIVERSITY OF SINGAPORE
Field: Computer technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 0:
1. A triboelectric sensor comprising:
a substrate;
at least one grid structure disposed in or on the substrate; and
at least one electrode for collecting triboelectric charges that are generated by sliding of an object over a surface of the substrate, the at least one electrode comprising at least one pair of electrodes, respective electrodes of the pair being located at opposite sides of the substrate; and wherein:
wherein the at least one grid structure is configured such that motion of the object is detectable from a signal generated by crossing of the object over at least part of the grid structure, the at least one grid structure comprising a spacing structure, said spacing structure comprising a plurality of raised portions, the raised portions having a constant height, such that transport of the object along the surface of the substrate generates a separation of charges between the surface and the object when the object encounters one of said raised portions, and such that motion parameters of the object are derivable from a ratio of electric potentials of said pair of electrodes.
