A study on the output performance and application of fiber-based triboelectric nanogenerators

Abstract

In this study a CO2 laser was used to develop a fiber-based triboelectric nanogenerator with microneedle array structure using commercially available polyester fiber and conductive fiber coating with PDMS and its production cost is low fast and non-toxic Due to the increased friction area of the microneedle array the highest open-circuit voltage reached 136 8 V and the short-circuit current reached 73 4 μA Compared with the unstructured fiber-based triboelectric nanogenerator the growth was 2 5 and 2 8 times respectively In terms of power density compared with the unstructured sample the microneedle structure has a 7 9 times greater performance improvement to 1 097 W/m2 At the same time it still maintains good electrical output performance in the 5000-cycle durability test and washing test In human motion detection test it can not only detect the motion of large and small joints but also light up 133 LEDs so that it has the development potential of self-powered and smart sensors
