In the Beyond e-Textiles project material research is combined with design explorations looking at the possibilities of solar radiation as a source to initiate change in textiles. Solar radiation of visible light and, to humans’ eyes, non-visible ultraviolet (UV) radiation, can trigger visual and structural changes in textiles. One question is how we can perceive solar radiation through textile objects, leading to the question if another perception can make us more aware of the not man-made parts of the world.
