Abstract

See full text

Disclosed are a method of directly patterning a stretchable substrate; and a stretchable electrode fabricated by the method. More particularly, the method of directly patterning a stretchable substrate includes: forming a hydrophilic group on a surface of a stretchable substrate by UV-ozone treatment; forming at least one layer to be etched on the hydrophilic group-formed stretchable substrate, wherein the at least one layer to be etched includes an adhesion enhancing material; forming a photoresist layer on the at least one layer to be etched; exposing the photoresist layer; and patterning the at least one layer to be etched using the exposed photoresist layer, wherein a carbon chain included in the adhesion enhancing material forms ether bonding (R—O—R) with a hydrophilic group formed on the surface of the stretchable substrate.
