Recently, in the field of electronic skin (E-skin), research and development of a visualization touch sensor capable of instantaneously recognizing external physics stimuli have been actively conducted. Photonic skin is a sensor that can detect external stimuli by generating visual human-readable response through induced color and/or light intensity changes in E-skin, which acts as human-machine interface. In this talk, we propose a new type of photonic skin which is electrochemically-driven based on MEH-PPV that shows electrochromic and light emitting features under low voltage condition. Ionic liquid ([EMIM][TFSI]) and thermoplastic polyurethane (TPU) film prepared under an optimal condition, as a role of iontronic polymer pump, could serve an ion storage layer and also enable a freestanding structure. As a result, we expect that our digital devices can be applicable to digital tactile sensors under dark/light atmosphere, simultaneously. |
