Textile industry is an old industry but there is plenty of space to innovate. One research topic going to shape our life and create new fashion is textile-based wearable electronics. As most textile engineering or fiber science students know how to make fiber functional, scalable manufacturing of functional fibers may not be easy. Also, making various daily textile products from functional fibers is another challenge. Further, how can we make good use of wearable electronics and what can we learn with such wearable electronics. In this talk, I will first show you scalable manufacturing of tactile sensing fibers from simple materials with customized setup, and then make them into daily textile products through computational design and digital machine knitting. Lastly, I will show you how we leverage machine learning to make our sensing textiles smart and use them to study human-environment interaction. Besides, I also would like to briefly share some other research related to fibers and manufacturing.
