Title:
LAMB WAVE RESONATOR-BASED PARTICLE CONCENTRATOR AND OPERATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/029153
Kind Code:
A1
Abstract:
A Lamb wave resonator-based particle concentrator and an operation method therefor. A Lamb wave resonator-based particle concentrator (300) comprises a silicon substrate (302); a Lamb wave resonator array comprises a plurality of Lamb wave resonators (304, 306, 308, 310) located on a front surface of the silicon substrate (302) and provided at vertexes of a regular polygon, and the angle formed by the electrode strip of each Lamb wave resonator (304, 306, 308, 310) and the electrode strip of an adjacent Lamb wave resonator (304, 306, 308, 310) is equal to the inner angle of the regular polygon. The Lamb wave resonator-based particle concentrator can realize the operation, control and aggregation of micro-concentration substances in a possibly small space, and increase the concentration of a detected substance by a large multiple at a specific position in an open space, thereby further reducing the size of the particle concentrator, without the need to design a micro-channel.
