Photochemical metallization allows the manufacture of touchscreens in a single step

In order for touchscreens on smartphones and tablets to function, microscopically fine conductor paths are required on their surfaces. When the users' fingers tip on or wipe over them, electrical circuits open and close, thus making the different functions of the smartphone possible. At the edges of the appliances, these microscopic circuit paths come together to form larger conductive paths. Until now, these different conductive paths had to be manufactured in several steps in time-consuming pr
