Abstract

Organogel-based stretchable electronic conductors exhibit electrical conduction even under a large stretching deformation of 300% without electrochemical reactions at DC voltages. The resistance change with stretching is almost strain-insensitive up to 50% strain and it remains at each deformation up to 1000 fatigue cycle. The polymeric conductive paths of

Pedot: PSS are well preserved during the mechanical deformation.

Keywords: PEDOT:PSS organogels; environmental stability; strain insensitivity; stretchable electronic conductors.
