Abstract
In recent years, the piezoelectric jet and atomization devices have exhibited tremendous advantages including their simple construction, and the fact that they are discreet and portable as well as low cost. They have been widely used in cell printing, spray cooling, drug delivery, and other industry fields. First, in this paper, two different concepts of jet and atomization are defined, respectively. Secondly, based on these two concepts, the piezoelectric jet and atomization devices can be divided into two different categories: piezoelectric micro jet device and piezoelectric atomization device. According to the organizational structure, piezoelectric micro jet devices can be classified into four different models: bend mode, push mode, squeeze mode, and shear mode. In addition, their development history and structural characteristics are summarized, respectively. According to the location of applied energy, there are two kinds of piezoelectric atomization devices, i.e., the static mesh atomization device and the vibration mesh atomization device, and both their advantages and drawbacks are discussed. The research achievements are summarized in three aspects of cell printing, spray cooling, and drug delivery. Finally, the future development trends of piezoelectric jet and atomization devices are prospected and forecasted.
Highlights
It was found that the piezoelectric actuator belongs to a kind of inverse piezoelectric effect based on piezoelectric ceramic material, which can produce rotation or linear motion by controlling its mechanical deformation
When the liquid is occupied with jet and atomization devices arehigher classified and thoroughly analyzed, their future dean absolute proportion of ejected material than the gas, it and is regard as jet; otherwise, it will be defined as atomization
In 2008, Fan et al [25] proposed a type of piezoelectric inkjet nozzle and fabricated the piezoelectric ceramic into the shape of a buzzer
Summary
Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. Sci. 2021, 11, 5093 there is no literature to distinguish such concepts of jet and atomization, especially for what collectively refers to the two concepts of jet and atomization as the process of dispersing liquid into tinyand droplets. Theother work on the evolutionmicro and jet progress of the constructions have been proposed for many years, but due to the limitations of the technical level, there piezoelectric micro jet isand atomization devices in the past three decades are reviewed and no literature to distinguish such concepts of jet and atomization, especially for what summarized. When the liquid is occupied with jet and atomization devices arehigher classified and thoroughly analyzed, their future dean absolute proportion of ejected material than the gas, it and is regard as jet; otherwise, it will be defined as atomization. The work on the evolution and progress trend of the constructions of piezoelectric micro jet and atomization devices in the past three decades are reviewed
