Piezoceramic is ubiquitously used in high-performance sensors and actuators. Three-dimensional (3D) printing of lead zirconate titanate (PZT) is attractive and highly desired for such device applications, but most of the existing methods are inherently limited to micron resolution, which makes them untenable for fabricating complex 3D architectures with high-definition features. Here, an electrohydrodynamic jet (E-Jet) nanoprinting strategy has been proposed to fabricate PZT 3D structures with the characteristics of flexibility and scalability. Different kinds of 3D PZT true nanostructures (resolution similar to 40 nm, aspect ratio similar to 400) were directly fabricated using a 100 mu m-sized nozzle. And the PZT nanostructures exhibited well-developed perovskite crystal morphology, large elastic strain (elongation approximate to 13%), and high piezoelectric property (d31 approximate to (236.5 x 10-12) CN-1). A bionic PZT air-flow sensor was printed to monitor air-flow detection, demonstrating well sensitivity with ultra-slow air-flow of 0.02 ms-1. The discovery reveals an efficient pathway to 3D-printing PZT nanostructures for next-generation high-performance piezoelectric devices. A 3D nanoprinting piezoceramic method was *** PZT nanostructures were directly printed under controllability and *** printed nanostructure exhibited excellent performance.A new strategy for the next-generation nanoscale additive manufacturing was provided.
