In the third and penultimate block, I had initially announced to you that I would present and present my personal top ten with regard to healthy materials. It is important to me to say that it is perhaps a somewhat unusual top ten in this regard.

You can imagine yourself as a material collector in the room sample, I am regularly asked what my favorite material is at the moment. I find it difficult to do this because this great, great diversity makes me see and know so many aspects that it is also very difficult for me to define this one material.

But my answer to today's topic of healthy materials fits very well: skin. Deliberately not my skin. As a material that I am incredibly enthusiastic about, I actually find our human façade, our human shell. A healthy material par excellence, renewable, self-healing, diffusing, haptic, appeals to all senses, highly sensory.

A material, if you like, that does not yet exist in the world of materials, i.e. plastics, building materials of this complexity, as of today. I would be very, very pleased to combine healthy materials, healthy construction, if it was actually possible to take more account of skin-like properties in a wide variety of materials.

When it comes to the top ten materials, it is important for me to make it clear that this is not a rating, i.e. what I have drawn so far has not made it into the top ten. That is by no means the case. There was more the consideration of what has already been shown, I can put in the top ten than everything. The top ten is a personal top ten, which I have put together once again to provide a final framework for this big topic of healthy materials, to give you another ten impulses.
