Abstract
Provided is a capacitive sensor device capable of detecting the position and magnitude of external force with high accuracy.
Employed is a capacitive sensor which comprises pairs of electrodes arranged in a matrix, each of the pairs of electrodes being disposed to face each other with a distance therebetween, and an elastically deformable dielectric layer arranged between each of the pairs of electrodes. A capacitance measuring part measures capacitance of respective electrode pair groups in a plurality of combinations each comprising more than one of the pairs of electrodes including a selected one of the pairs of electrodes. An external force calculating part calculates the magnitude of external force applied to the position of the selected pair of electrodes based on a plurality of measured values of the capacitance.
