Abstract

In a capacitive sensor on at least one carrier (2, 4) made of transparent material, e. g. glass, it is provided that the transparent carrier (2,4) comprises an electrically conducting transparent layer (6,10) which serves as a transparent sensor surface.

Claims

1. A capacitive sensor comprising at least one carrier (2, 4) made of transparent material, said at least one transparent material carrier (2,4) including a plurality of electrically conducting transparent layers (6, 10) defining a transparent sensor surface, said plurality of electrically conducting transparent layers (6, 10) establish capacitive functions which penetrate each other, said plurality of electrically conducting transparent layers extend diagonally, and two sensor surfaces lying one upon the other establish path-type electrically conducting layers (6, 10) diagonally extending in opposite directions.

2. A capacitive sensor comprising at least one carrier (2, 4) made of transparent material, said at least one transparent material carrier (2, 4) Including an electrically conducting transparent layer (6, 10) defining a transparent sensor surface, said electrically conducting transparent layers (6, 10) being subdivided by a plurality of insulation paths (11) into separate sensor surfaces, independent capacitive sensors being connected to each separate sensor surface, and said electrically conducting transparent layer (6, 10) includes enlargements (8, 12).

3. The capacitive sensor as defined in claim 2 wherein the electrically conducting transparent layers (6, 10) of neighbouring sensor surfaces cross each other between respective enlargements (8, 12).

4. A capacitive sensor comprising at least one carrier (2, 4) made of transparent material, said at least one transparent material carrier (2,4) including a plurality of electrically conducting transparent layers (6, 10) defining a transparent sensor surface, said plurality of electrically conducting transparent layers extend diagonally, and two sensors lying one upon the other establish path-type electrically conducting layers (6, 10) diagonally extending in opposite directions.

5. A capacitive sensor comprising at least one carrier (2, 4) made of transparent material, said at least one transparent material carrier (2, 4) including an electrically conducting transparent layer (6, 10) defining a transparent sensor surface, and said electrically conducting transparent layer (6, 10) includes enlargements (8, 12).

6. The capacitive sensor as defined in claim 5 wherein electrically conducting transparent layers (6, 10) of neighbouring sensor surfaces cross each other between respective enlargements (8, 12).
