Autonomously adapting and communicating modular textiles

This project contributes to a paradigm shift for smart soft materials into user-customizable textiles that autonomously interact with their environment and communicate through changes in color or shape. This will be done by coupling modular thermo- and photo-actuators to the traditional European fiber art of bobbin lace.

The envisioned color-shape-communicative textile networks will include an on/off command of embedded functionalities by modifying an established concept – coiled yarn thermoactuators – to have different selective coatings on inner and outer surfaces of the coils.

Furthermore, I will create unprecedented photoactuating coiled yarns, in which visible light turns on the functionality in a thread.

The developed non-conformal coating techniques will also enable multifunctional threads, in which different parts of the thread can be commanded by different wavelengths of light.I will also develop two-dimensional multifunctional structures using these thermo- and photo-actuating threads as building blocks.

The modularity of these building blocks, combined with the multiple thread system and three different braiding actions of bobbin lace, will enable a wide combinatorial parameter space for interactive network structures.

I will demonstrate a textile that can, either upon illumination or thermal stimulus, change its color, its breathability/permeability, and activate a third function, such as colorimetric detection of a biomarker.

These textiles could be used in clothes or window shades, e.g., adapting their warming/cooling capacity based on the external temperature or solar illumination.

Such functional textiles would indirectly decrease the need for heating/cooling many buildings and allow energy savings, thus providing an important economic opportunity.

Co-creating further textile innovations with communities of bobbin lacemakers will ensure that the impact of the action goes beyond the conventional in terms of both technological and societal impact.
