1. A conductive polymer composite adhesive to a flexible substrate, comprising:
a polymer adhesive comprising a curable polymer and a curing agent; and
a conductive filler consisting of a metal and a carbonaceous material,
wherein the metal and the carbonaceous material are dispersed in the polymer adhesive by using a chloroform,
wherein the metal has a mixture of a first metal particle having a diameter of 100 to 200 nm, a second metal particle having a diameter of 1 to 4 μm, and a third metal particle having a diameter of 5 to 10 μm,
wherein the carbonaceous material is a multi-walled nanotube,
wherein the carbonaceous material is present in an amount of 0.1 to 2 parts by weight based on 100 parts by weight of the metal,
wherein the conductive filler is present in an amount of 100 to 500 parts by weight based on 100 parts by weight of the polymer adhesive,
wherein the flexible substrate comprises a polydimethylsiloxane (PDMS).
