Polymer tubes as carrier boats of thermosetting and powder materials based on 3D printing for triboelectric nanogenerator with microstructure

This study reports a novel strategy for rapidly fabricating TENG with micro/nanostructures based on FDM, which significantly improves the electric performance of TENG. The optimal output performance of TENG is η = 74.4% and Q = 236.67 W/m3 (306 V, 6.14 mA) at 30 Hz. This method overcomes drawbacks of traditional 3D printing but inherits its advantages, which can take a big step forward for the industrialization of individualized TENG.284
