Piezoelectric micro-jet devices: A review

Sensors and Actuators A: Physical, 2019
Abstract Piezoelectric micro-jet devices (PMJDs), also known as piezoelectric inkjet printing, are used to distribute the functional materials to form single or complex microstructures on a substrate. As one of the most promising technologies in the field of additive manufacturing in the 21st century, the PMJDs have received a lot of attentions from ...

Development of a resonant piezoelectric micro-jet for high-viscosity liquid using a longitudinal transducer

Mechanical Systems and Signal Processing, 2021
Abstract A resonant piezoelectric micro-jet (RPMJ) using a longitudinal transducer (LT) is proposed for achieving high-speed jetting of high-viscosity liquid. The continuous droplets are realized by the pressure change of micro-jet element (MJE) which can be generated by the high frequency vibration of the LT.

Waveform Optimization of Piezoelectric Micro-Jet for the Control of Metal Micro-Droplet Ejection

IEEE Transactions on Industrial Electronics, 2022
On-demand metal droplet ejection is a critical technical branch in industrial electronics. Among them, high temperature and surface tension are the mainly limited factors affecting the single droplet ejection of hot-melt metal. To this end, this work proposed a waveform optimization scheme based on a piezoelectric micro-jet device (PMJD) actuated by a ...
