Abstract
A number of applications such as displays, touch sensors, and ultrathin heating elements contain flexible and optically transparent plastic films covered with highly electrically conductive coatings. In most cases, indium tin oxide (ITO) is used as the conductive material for these coatings due to its additional property of being transparent to visible light. Once deposited onto the foil, ITO has to be patterned before use, which is generally a tricky, time-consuming, and costly process. A newly developed economical roll-to-roll printing process utilizing metallic grids now offers a direct print alternative with better functional characteristics.
