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, 2022On-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 ...
