Sensory feedback from external stimulus is critical for many tasks carried out by robots and humans, such as identifying objects or detecting hazards. Electronic skin is a crucial technology for these purposes, which can play the roles of human skin. However, some problems still remain a distant possibility because of hard issues in resilience, manufacturing, sensorics, etc due to the intrinsic problems of organic- or polymer-based materials. Nonetheless, progress over the past few years in relation with the above issues has been encouraging. In this study, we focus to present the results for chemical sensors by applying solvatochromic materials with twisted intramolecular charge-transfer behavior depending on the polarity of the surrounding molecules, as an auxiliary sensing medium. The developed chemical sensors were demonstrated to effectively detect chemical elements. These results are expected to contribute to the development of sensing media to improve the performance of chemical sensors and to bring some fresh ideas in this field in the future.
