Abstract (en)
The safety unit has a carrier substrate, and a printed layer in the form of lines or other geometries, where the layer is arranged on the substrate. An analog signal is realized in printing by a leading and trailing edge modulation for forming the printed layer, and is developed as a completely printed unit. The analog signal is converted into acoustic signal by detecting and reading the signal with software, where the acoustic signal is present in the form of word, text, noise or music.
