Abstract
The invention relates to a method for generating at least one electrically contactable area on a polymer which is doped with a conductive substance, wherein a contact material is applied onto the polymer, which has a lower specific resistance at 23° C. than the polymer. According to the invention the contact material is applied onto the polymer so tightly that close contact between the contact material and the conductive substance is achieved. Due to the tight application of the contact material, which has a lower specific resistance than the polymer, the input resistance of the doped polymer is effectively reduced. The invention further concerns a formed body made of a polymer which is doped with a conductive substance, which has at least one contactable area, within which a contact material is applied onto the polymer, which has a lower specific resistance at 23° C. than the polymer. According to the invention the contact material is applied onto the polymer so tightly that it is in close contact to the conductive substance. Such formed body has a significantly reduced input resistance.
