Abstract
A pressure distribution sensor utilizing electromagnetic coupling in which alignment of electromagnetically coupled coils is facilitated, and a force in a slip direction can be detected. The pressure distribution sensor utilizing electromagnetic coupling has a detection surface comprises a plurality of first loop wires (1) arranged in parallel on the same plane, a plurality of second loop wires (2) arranged in parallel on the same plane in the direction perpendicular to the first loop wires (1), and a plurality of third loop wires (3) arranged in parallel on the same plane as the first loop wires. The third loop wires (3) are formed to be connectable to a drive section (10) in a separated manner from the first loop wires. The drive section (10) connected to the first loop wires drives the first loop wires, and a detecting section (20) connected to the second loop wires detects pressure from detection signals based on electromagnetic coupling at the electromagnetic coupling portions from the second loop wires.
