| 1 | Continuouss Three-Dimensional Printing of Architected Piezoelectric Sensors in Minutes显示文摘Additive manufacturing(AM),also known as three-dimensional(3D)printing,is thriving as an effective and robust method in fabricating architected piezoelectric structures,yet most of the commonly adopted printing techniques often face the inherent speed-accuracy trade-off,limiting their speed in manufacturing sophisticated parts containing micro-/nanoscale features.Herein,stabilized,photo-curable resins comprising chemically functionalized piezoelectric nanoparticles(PiezoNPs)were formulated,from which microscale architected 3D piezoelectric structures were printed continuously via micro continuous liquid interface production(μCLIP)at speeds of up to~60μm s^(-1),which are more than 10 times faster than the previously reported stereolithography-based works.The 3D-printed functionalized barium titanate(f-BTO)composites reveal a bulk piezoelectric charge constant d33 of 27.70 pC N^(-1) with the 30 wt%f-BTO.Moreover,rationally designed lattice structures that manifested enhanced,tailorable piezoelectric sensing performance as well as mechanical flexibility were tested and explored in diverse flexible and wearable self-powered sensing applications,e.g.,motion recognition and respiratory monitoring. | SiyingLiu Wenbo Wang Weiheng Xu Luyang Liu Wenlong Zhang Kenan Song Xiangfan Chen | 2022 | Research2022，，4： | 0 |
