| titleOfInvention | Particle control device based on Rayleigh wave and Lamb wave and its preparation and control method |
| abstract | The invention discloses a particle control device based on Rayleigh waves and Lamb waves and a preparation and control method thereof. Existing microfluidic platforms cannot adjust the displacement of the particle's Z-axis. One side of the piezoelectric substrate of the present invention is provided with a base interdigital transducer, a piezoelectric substrate positioning point and a cavity wall, the cavity wall is placed on the inner edge of the piezoelectric substrate positioning point, and the base interdigital transducer is placed in the cavity Outside the body wall; a top interdigital transducer and a piezoelectric top cover positioning point are arranged on one side of the piezoelectric top cover, and the piezoelectric top cover positioning point is located inside the top interdigital transducer; the piezoelectric top cover positioning point is the same as the The positioning points of the piezoelectric substrate are aligned and arranged; a cavity is formed between the piezoelectric top cover, the cavity wall and the piezoelectric base. The invention excites Lamb waves on the interdigital transducers of the piezoelectric top cover, and excites Rayleigh waves on the interdigital transducers of the piezoelectric substrate, adjusts the driving signals of the top and bottom interdigital transducers, and controls The sound pressure distribution in the Z direction in the cavity finally realizes the deterministic movement of the controlled particles on the XYZ plane. |
