Resistive pressure sensor including piezo-resistive electrode

A pressure sensor comprising:

• an elastic thin film comprising a first surface and a second surface that face each other, the elastic thin film comprising an elastomer material, and the first surface being patterned to have a plurality of protruding deformable structures;
• a piezoresistive electrode formed along surfaces of the plurality of protruding deformable structures, the piezoresistive electrode being shaped to protrude in accordance with a shape of the plurality of protruding deformable structures;
• and
• a counter electrode disposed to face the piezoresistive electrode,
• wherein the piezoresistive electrode protrudes toward the counter electrode, and
• wherein as pressure applied to the counter electrode becomes stronger, a contact area between the piezoresistive electrode and the counter electrode becomes larger.
