The Effect of Vibration Characteristics on the Atomization Rate in a Micro-Tapered Aperture Atomizer [PDF]

Sensors, 2018
Because little is known about the atomization theory of a micro-tapered aperture atomizer, we investigated the vibration characteristics of this type of atomizer.

Sound-focusing package for MEMS vector hydrophone [PDF]

Microsystems & Nanoengineering
To address the challenge of acoustic wave attenuation in traditional Micro-Electro-Mechanical Systems (MEMS) vector hydrophone packaging, this study proposes a sound-focusing package with tapered apertures (TA) and a nylon sound-focusing cap (NSC ...

Experimental Verification of the Pumping Effect Caused by the Micro-Tapered Hole in a Piezoelectric Atomizer

Sensors, 2018
In this study, we examined the use of a dynamic micro-tapered hole as a micro-scale tapered flow tube valveless piezoelectric pump. Firstly, we obtained photographs of a micro-tapered hole by using an environmental scanning electron microscope (ESEM ...

Study on the Influencing Factors of the Atomization Rate in a Piezoceramic Vibrating Mesh Atomizer

Applied Sciences, 2020
On the basis of previous study in our research group, the phenomenon of the dynamic tapered angle was founded, the occurrence of atomization is regarded to derive from the combined effects of the dynamic variation of the micro-tapered aperture, and the ...
