Patent ID: 8904885

Claim:
A detection device that detects an intensity and a direction of an external force applied to a first substrate, a second substrate and a third substrate, the detection device comprising: the first substrate that includes a plurality of first capacitor electrodes disposed on a surface of the first substrate; the second substrate disposed to face the first substrate, the plurality of first capacitor electrodes being disposed between the first substrate and the second substrate; a second capacitor electrode disposed to face the surface of the first substrate on which the plurality of first capacitor electrodes are disposed, the second capacitor electrode being disposed on the second substrate; a dielectric body disposed between the first substrate and the second substrate, the dielectric body being formed of an elastic body or fluid; and a third substrate having an elastic projection at one end portion, the elastic projection defining a tip, the tip of the elastic projection contacting the second substrate when the second substrate is elastically deformed by external pressure, and the tip of the elastic projection protruding away from the third substrate.
