Enhancing Interior Surfaces

As part of an innovative research project in the scope of EDIH Applied CPS, the integration of printed electronics into standard ceramic tiles was successfully demonstrated. The goal was to explore the feasibility of creating functional yet aesthetically pleasing interior surfaces by combining printed touch sensors and electroluminescent (EL) lighting elements.

The main challenges included ensuring the adhesion of functional materials to ceramic surfaces, maintaining electrical conductivity, and achieving stability and robustness of the printed elements. In collaboration with Silicon Austria Labs, various conductive, insulating, and luminescent materials were evaluated in terms of their processability and functionality.

The outcome is a functional demonstrator module consisting of a printed capacitive touch sensor combined with a printed EL display on a commercially available tile. The display can be turned on and off with a simple touch and remains visually discreet when inactive.

This development impressively demonstrates how digital functionality can be seamlessly integrated into traditional building materials. It opens up new possibilities for interactive wall surfaces, smart control elements, and ambient lighting design in architectural and interior spaces. This project significantly contributes to the digitalization of the construction industry and to the advancement of printed electronics for everyday applications.
