Smart Fabric Warning of Radiation Heads to Space

Just as high radiation damages human DNA, the fading of pigments in bacteria injected into the fabric forms the basis of a smart early warning system. The goal of the project is to add protective properties to space suits using a sustainable and biological method instead of synthetic dyes.

Pigmented Space Pioneers, an ambitious project intersecting the worlds of science and fashion, is developing a technology with the potential to revolutionize space exploration. The main goal of the project is to produce radiation-sensitive, color-changing smart fabrics using dyes produced by certain special bacteria.

Developed in collaboration with scientists and fashion designers from the University of Glasgow, these fabrics not only offer biological and sustainable dyes but also give a warning by changing color when exposed to dangerous levels of radiation. Project leader Dr. Gilles Bailet explains that just as radiation exposure breaks down human DNA, pigments in bacteria also break down and color saturation decreases. Bailet states that they aim to use this visual response to create a visible early warning system that does not require electronics or batteries to protect astronauts on the Lunar surface or in further explorations. At the same time, this fabric can serve as a protective coating for sensitive equipment.

Bacteria and 3D Printing Technology

The fabrics were produced using six different harmless bacteria types capable of producing different colors like red, yellow, and blue. The pigments of these microbes provide natural protection against environmental stresses. Bacteria are injected into the fabric in precise patterns using special needles and 3D printing techniques. When the bacteria die, their colors remain inside the fabric.

Designer Katie Tubbing states that the developed fabric has a design that is both visually interesting and easy to read, and the fading of the dye indicates potential dangerous radiation exposure at a glance.

This technology could have potential uses not only for space but also on Earth. For example, it is possible to produce radiation-sensitive aprons for medical imaging personnel or clothing that can warn people about excessive sunlight exposure and reduce the risk of skin cancer. Among the bacteria reproduced at ASCUS – Art and Science Lab, there are common species that can even be found in the bathroom. This approach carries the potential to make garment dyeing more sustainable, countering the risk of synthetic dyes polluting water sources.

The next phase of the project aims to test it during a space journey. Pigmented Space Pioneers plans to send the first piece of fabric to space in February 2026 in collaboration with an Edinburgh-based space startup.
