Abstract
A method and the device for position detection are disclosed. The device comprises a plurality of strips intersecting each other to form a plurality of intersecting regions. A pair of depressed strips intersecting on an intersecting region contact to each other on a contact point to form a depressed intersecting region, wherein the contact impedance of the contact point is determined according to the position of the depressed intersecting region and the voltages on the contact point of one and the other of the pair depressed strips.
