P7.12 - Textile-Structured Triboelectric Nanogenerators for Wearable Electronics 
April 9, 2015   11:45am - 12:00pm

Wearable and self-powered devices have represented the emerging technology necessary to new life pattern of human. Textile structures are desirable for wearable device that are stretchable and flexible. In this article, a new textile-structured triboelectric nanogenerators are demonstrated for powering to the wearable devices. The tube-type triboelectric nanogenerator consists of PDMS tube, copper wire in center of device, and aluminum wrapped around the outer surface of tube, which are utilized to generate and harvest triboelectricity. We also fabricate the cable-type triboelectric nanogenerator, which is composed of several tube-type nanogenerator with series connection, resulting in 3 times higher output voltage than that of a tube-type nanogenerator. Additionally, textile-type triboelectric nanogenerator is fabricated with weaving from numerous tube-type triboelectric nanogenerator with parallel connection to generate high output current. A maximum output voltages and currents of 50 V and 250 �A for the textile-structured nanogenerator are obtained under the vertical stress of pushing tester. Moreover, the relationship between output performance and the amount of deformation at stretchable loading in the stretchable textile-type triboelectric nanogenerator is also investigated. This work should play an important role in new direction to wearable electronics.
