German Design Graduates Special

What Role Does Experimental Design Play as a Driver of Innovation?

In this special edition of Design Perspectives, we explore how experimental design can spark innovation between the laboratory and industry. Host Jasmin Jouhar talks to Miriam Johnston, a graduate of Burg Giebichenstein University of Art and Design Halle, and Johannes Voelchert, Innovation Design Lead at On Shoes in Zurich. The occasion for this special episode is the exhibition Dare to Design – Spaces of Care, on view at the Museum of Applied Arts Cologne (MAKK) until 12 October 2025. The show features projects by this year’s German Design Graduates, an initiative of the German Design Council supporting graduates of German design universities. Among them: the Master’s project Biophilic Colours by Miriam Johnston, selected as a Spotlight Project by Johannes Voelchert.

Key Learnings

Design in the Lab: Biophilic Colours
Miriam Johnston explores structural colours generated through the growth of flavobacteria. With 3D-printed biotubes, she creates habitats in which microorganisms produce iridescent colour patterns. Her approach demonstrates how designers can be integrated as equal collaborators in scientific research processes.

From Experiment to Scale: LightSpray at On
During his studies, Johannes Voelchert developed a process in which a shoe’s upper material is sprayed directly onto its sole. At On, this technology has been further developed over several years – with the challenge of scaling it up to industrial levels. His work shows how experimental design can create tangible impact in industry when persistence meets iterative problem-solving.

Interdisciplinarity as Key
Both guests emphasise the role of designers as bridge-builders between disciplines. Whether in biotechnology, materials research, or manufacturing innovation – the crucial skill lies in connecting knowledge, contributing new perspectives, and translating complex ideas into forms accessible to science, business, and society alike.

The Podcast of the German Design Council

Design Perspectives Podcast

How can we use design as a lever for transformation and economic success? We talk about this with personalities from the fields of design, brand management and architecture. They give us insights into how transformation, sustainability and economic success can go hand in hand in a company. Interesting, informative, inspiring.
