CNTs-related materials have excellent physical and chemical properties, and can be adaptable for various applications including solar cells and capacitors. Furthermore, CNT films exhibit flexibility and broadband photo-absorption properties, making them suitable for stereoscopic imaging by employing CNT films as photo-thermoelectric imagers. On the other hand, from the viewpoint of imaging usage, fine integration is essential to facilitate high-resolution visualization, video capturing applications, and so on.
The conventional method employs the suction filtration process for fabricating the CNT film-type broadband flexible imagers. The device consists of CNT film channels and electrodes, and also requires the chemical carrier doping on the channel. However, manual alignment of each device material component, which is associated with the suction filtration, has been a bottleneck for realizing the fine-integration of the CNT film imager. To this end, this work reports on the all-printable device fabrication by inkjet dispensers, enabling mechanical alignment of each device material component.
