Patent ID: 7800362

Claim:
A pressure distribution detector utilizing electromagnetic coupling comprising: a plurality of drive wires each arranged in a looped pattern on a substrate; a plurality of detection wires each arranged in a looped pattern so as to be electromagnetically coupled to each of the plurality of drive wires; a plurality of electromagnetic coupling portions configured to allow the drive wires and the detection wires to be electromagnetically coupled to each other; a spacer keeping a constant distance between the plurality of drive wires and the plurality of detection wires; a variable electromagnetic coupling changing a degree of electromagnetic coupling at each of the plurality of electromagnetic coupling portions in accordance with a move due to pressure, which is movably provided adjacent to the plurality of electromagnetic coupling portions; a drive section connected to the plurality of drive wires so as to drive the plurality of drive wires; and a detection section connected to the plurality of detection wires so as to detect a change in the degree of electromagnetic coupling at each of the electromagnetic coupling portions from the plurality of detection wires.
