Patent ID: 6927584

Claim:
A circuit arrangement comprising i sensor elements, said i sensor elements being interconnected in an (n×m) matrix circuit configuration with n row conductors and m column conductors, where i, n and m are natural numbers different than zero and where 1≦i≦n*m, each of said n row conductors and m column conductors comprising a first conductor end and a second conductor end, wherein said first conductor end of the n row conductors and m column conductors is connectable to an evaluation circuit, and wherein each of said i sensor elements is connected between two respective conductors from said n row conductors and said m column conductors, said circuit arrangement further comprising at least one return conductor having a first conductor end and a second conductor end, wherein said first conductor end of said at least one return conductor is connectable to said evaluation circuit and said second conductor end of said at least one return conductor is in contact with said second conductor end of one of said n row conductors or one of said m column conductors.
