Abstract: Disclosed is a thermoelectric device in which a separate interlayer is inserted between a thermoelectric leg and an electrode to reduce the contact resistance between the thermoelectric leg and the electrode, so that the interlayer serves as a tunneling path between the thermoelectric leg and the electrode, facilitating the charge movements between the two materials. The thermoelectric device according to an embodiment includes a substrate; at least one thermoelectric leg positioned on the substrate; an interlayer positioned on each thermoelectric leg of the at least one thermoelectric leg and including a plurality of interlayer materials that are chemically bonded with a respective thermoelectric leg; and an electrode positioned on each interlayer and electrically connected to the respective thermoelectric leg, wherein the plurality of interlayer materials of each respective interlayer is arranged in a shape of a brush.

Abstract: A conductive polymer composite for adhesion to a flexible substrate contains a polymer adhesive containing a curable polymer and a curing agent; and a conductive filler containing a metal and a carbonaceous material dispersed in the polymer adhesive. The conductive polymer composite is suitable for application to not only the human body but also other objects having irregular surface. In addition, due to enhanced adhesive strength of the conductive polymer composite to the flexible substrate, the reduction in conductivity or conductivity breakdown caused by external stress can be prevented and flexibility and stretchability can be improved.
