Fabrication of Flexible Devices by Inkjet Printing

Currently, flexible devices have a wide range of applications such as health managements, drug deliveries, and electronic skins. The inkjet printing is considered the most promising technology for manufacturing flexible devices due to its high resolution, large scale, and low cost. Here, we give a comprehensive review of the fabrication of flexible devices by inkjet printing. First, we introduce the different types of inkjet printing, including continuous inkjet printing and on-demand inkjet printing. In addition, we describe flexible substrates and nano-metallic inks for preparation of flexible devices. Lastly, the perspectives for future development of flexible devices are proposed.
