Semiconductive cotton was developed in Heat Harvest -project, within Aalto Energy Efficiency Research Programme. Together with Aalto CHEM, we looked for different yarns and textiles to be used as a substrate for atomic layer deposition.

The overall project is managed from CHEM, while I managed Aalto ARTS-side. The project focuses on energy harvesting from thermal exchange, and we looked at how natural fibers and textiles could be used with the atomic layer deposition process, and what could be the implications for design.

This work has resulted  in several publications, I was also an advisor to CHEM MSc thesis.
