A substrate for use in an electronic skin is disclosed herein. The substrate comprises a base polymer layer, and a first intermediate polymer layer attached to the base polymer layer by a first adhesive layer. The first intermediate polymer layer comprises a first intermediate polymer in which electron-rich groups are linked directly to one another or by optionally substituted C1-4 alkanediyl groups. A first conductive layer is attached to the first intermediate polymer layer by a second adhesive layer or by multiple second adhesive layers between which a second intermediate polymer layer or a second conductive layer is disposed.
