The liquid motion control device has a control unit with an acoustic resonator (30) that is positioned in the path of SAW, and having a resonance cavity (30) between a pair of acoustic reflectors (31a,31b), which is arranged consecutively with respect to one another in the propagation direction of SAW. The acoustic resonator normally allows transmission of SAW having frequency equal to resonance frequency, and reflects SAW when quantity of liquid is present within the acoustic resonator.

Liquid motion control device for Lab-on-a-Chip (LOC) system of e.g. food analysis apparatus, has control unit with acoustic resonator that reflects surface acoustic wave (SAW) when quantity of liquid is present within acoustic resonator

Abstract

The liquid motion control device has a control unit with an acoustic resonator (30) that is positioned in the path of SAW, and having a resonance cavity (30) between a pair of acoustic reflectors (31a,31b), which is arranged consecutively with respect to one another in the propagation direction of SAW. The acoustic resonator normally allows transmission of SAW having frequency equal to resonance frequency, and reflects SAW when quantity of liquid is present within the acoustic resonator.
