Presentation Title:

Making Flexible and Wearable Electronics with Fibers and Textiles

Presentation Abstract:

Institute of Textiles and Clothing, The Hong Kong Polytechnic University, Kowloon, Hong Kong SAR, China

Flexible and wearable electronics are forseen to be the major technology in the next few decades. Conventional flexible and wearable electronic devices are fabricated on thin plastic or elastomeric thin films. These thin film devices can show remarkable device performance, however, the wearing ability is still quite limited. On the other hand, fibers and textiles are flexible and lightweight materials that have been worn by human beings hundreds of thousands of years. Compared with thin films, the three-dimensional fibre and textile structures not only provide superior flexibility, stretchability, drapability, but also breathability and washing ability. This talk will introduce how our research group makes use of the attributes of fibres for making conductive threads, electrodes, and high-performance wearable devices. We will particularly focus on the strategies and perspectives to modify fibers and textiles for making wearable capacitators and batteries with excellent mechanical durability, electrochemical stability, and high energy/power density.
