Dr Kai Yang 

Principal Research Fellow

EPSRC Research Fellow

Dr Kai Yang is a Principal Research Fellow in the Smart Electronic Materials and Systems (SEMS) Research group at the University of Southampton. She obtained her BSc (Hons) in Material Engineering from Beijing Institute of Fashion Technology in China in 2004; and PhD. in Chemistry for the University of Leeds in 2009. She has 10 years’ experience of e-textiles. Her work primarily focused on the e-textile materials, manufacturing and application development (e.g. healthcare, wearable technologies).

She has been awarded an EPSRC Innovation Fellowship (EP/S001654/1) in 2018 to develop “Advanced E-textiles for Wearable Therapeutics” with the initial application focusing on the osteoarthritis knee joint pain. The technology is also applicable for the knee joint pain caused by other conditions (e.g. injury, post-surgery pain) and other joint pain (e.g. back, shoulder, and hip).

She was PI on the £1.1 million SMARTmove project (www.smartmove.soton.ac.uk) funded by Medical Research Council (MRC). SMARTmove project has developed a textile based wearable Functional Electrical Stimulation (FES) training system for stroke upper limb rehabilitation.

She was Co-I of the EPSRC E-textiles Network (www.e-textiles-network.com). The Network is to bring together researchers and developers from academia and industry interested in adding electronic functionality to textiles and their related products. She is Co-Chair for E-textile Conference 2019.

She was the runner-up for the Royal Academy of Engineering ERA Foundation Entrepreneurs Award 2016 and is a RAEng Enterprise Hub member.  She was co-founder of University spin-out company Smart Fabric Inks (www.fabinks.com) which was established based on the know-how on the functional inks she co-developed for printing electronics on textiles. The company has sold inks to 10 countries worldwide. Smart Fabric Inks was a finalist for the Royal Society of Chemistry Emerging Technologies Competition 2017 and Merck Displaying Futures Award 2017.

Her other roles include: ECS Athena Swan Committee and ED&I Committee; Sensors special issue editor on ‘Smart Textiles and Wearable Sensors’; EPSRC Peer Review Associate College member; IEEE International Flexible Electronics Technology Conference (IFETC) 2018 & 2019 Technical Committee; CIMTEC 2020 International Advisory Board Committee of Symposium on ‘Smart and Interactive Textiles’.
