Abstract:

In order to well fit human body with flexible all-braided triboelectric nanogenerator (FTENG) and easily prepare FTNG, the FTNG was garmented. By using cone-spinningmethod, the skin-core structured composite yarns were formed by winding nylon (PA6) and polyester (PET) sewing yarn onto the surface of Ag fiber surface, respectively. These composite yarns were woven into self-powered fabrics with a shuttle, in which PA6 cortex cortex and PET were used as friction layer and the core layer of Ag fiber was used as electrode for effective biomechanical energy harvesting and active wearable electronics. Based on the skin-core structured composite yarns and the advanced 2-D structural design, the open circuit voltage and short circuit current are 20.0V and 1.50μA, respectively, and the maximum peak power density can reach 1.6mW/m-2. In addition, the collected power is capable of charging a commercial capacitor.
