Abstract

We propose a modular, fast and large-area fabrication of bio-piezoelectric films. The technique is based on the formation of cone-jet mode by applying a high voltage electric field to conductive spiked metal disks. And the self-assembly process of biomolecular materials through nanoconfinement with in-situ poling effect. This job achieved print speeds of up to 9.2 109 um3/s with a combination of only 2 printheads. At the same time, the modular design allows the MLSP to achieve theoretically unlimited print efficiency. It also provides flexible configuration options for different printing needs, such as preparing films of different areas and shapes. In short, MLSP demonstrates the ability of piezoelectric biomaterials to undergo ultra-fast, large-scale assembly. Demonstrates good potential as a universally applicable bio-device for the fabrication of bio-piezoelectric films
