Abstract
Input apparatus including at least one textile fabric carrier, at least one flexible, wire-and/or thread-like electrical conductor comprising at least one weft and/or warp thread of the fabric carrier, and at least one electrically conductive, flexible key device which is electrically connected to a key connection of the conductor, wherein the conductor is designed for the connection of an evaluation device.
Claims17
An input apparatus comprising:
- at least one textile fabric carrier;
- flexible, wire-like and/or thread-like electrical conductors, each comprising at least one weft and/or warp thread of the fabric carrier;
- and
- a plurality of electrically conductive, flexible key devices which are electrically connected to key connections of the conductors, are arranged in linear or in matrix-like fashion, and are in each case electrically connected at crossover points to contact redistribution conductors which run essentially perpendicular to at least one of the conductors and which each comprise at least one electrically conductive weft or warp thread of the fabric carrier;
- wherein at least one of the conductors is designed for connection of an evaluation device.
