  • Acoustic wave propagation device having medium for acoustic wave propagation and the making method of the medium for acoustic wave propagation
    Patent number: 12633892
    Abstract: The present invention relates to an acoustic wave transmission device for moving a fluid or fine particles inside the fluid to a desired position using acoustic waves, and more particularly, to an acoustic wave transmission device including an acoustic wave transmission medium that minimizes acoustic wave interference due to the acoustic wave transmission medium by reducing reflection and refraction that may be generated when acoustic waves pass through the acoustic wave transmission medium in which a fluid is accommodated, and a manufacturing method of the acoustic wave transmission medium.
