Carbon nanotube-based transparent stretchable millimeter-wave–infrared imager

This work develops a multi-functional imager sheet for the potential use in non-destructive inspection techniques. The presenting imager collectively satisfies optical transparency in the visible light band and stretchable broadband detector operations in millimeter-wave (MMW)–infrared (IR) regions. The device comprises different properties of carbon nanotube thin-films: single-walled metallic for photo-absorption and single-walled semiconducting for thermoelectric conversion, to demonstrate the above transparent MMW–IR imager configuration. By synergizing such characteristics with human vison sense, employing the device potentially enriches non-destructive inspection techniques as wearable modules.
