South Korean scientists of the Incheon University and the Inha University developed the world’s first silk based electronic textile manufacturing technology. It is based on graphene oxide coating on silk and requires no adhesive. Silk has the properties ease of hydrogen bonding and high-temperature resistance. The silk-based electronic textile showed little deformation after washing and bending. Meanwhile it maintained an electric conductivity of approximately 10 S/m comparable to those of existing ones. As a result, the textile can be produced with its performance intact, at a lower cost and within a shorter period of time.
