Photonic skin is a sensory device system that can directly reflect external stimuli by generating visual human-readable response through optical means such as light emitting or chromism. Electrochromism is the phenomenon that color of semiconducting materials is reversibly changed by electrochemical redox reaction. In this work, we report the first electrochemically-driven photonic skin based on highly deformable iontronic polymer pump. Ionic thermoplastic polyurethane film with ionic liquid ([EMIM+][TFSI-]) prepared under an optimal condition, as a role of functional elastomeric ion pumps, could serve good mechanical properties, high transmittance, and ionic conductivity. In addition, we could selectively migrate ions into the chromic material with a conductive pen under low voltage. This allows us to expect that our iontronic, photonic skin can be applicable to active touch board for directly visualized writing and erasing, reversibly for next generation human-machine soft interface. |
