Abstract
A sensor and a method of manufacturing the same are provided. The sensor includes a substrate, a projecting portion including a plurality of projections that protrude upwardly from an upper portion of the substrate, and an electrode portion covering the projections and the upper portion of the substrate between the projections. The projecting portion of the sensor has micro projections to enable the sensor to sense pressure and a sliding movement.
Claims18
A sensor, comprising:
- a substrate;
- a projecting portion comprising projections that protrude from an upper portion of the substrate in a first direction;
- and
- an electrode portion comprising a conductive material and covering the projections and the upper portion of the substrate between the projections,
- wherein the electrode portion comprises a continuous undulating cross section spanning from a first point on the substrate to a second point on the substrate, and
- wherein the projections comprise an elastic material and are configured to tilt in response to a horizontal force being applied to the projections.
