Abstract
An apparatus system for controlling liquid in a fluid channel in a micro-fluid device has an ultrasonic oscillator for conveying liquid. The ultrasonic oscillator oscillates with amplitude modulation. The apparatus system has a holding section for holding the micro-fluid device on the ultrasonic oscillator to allow a micro-fluid device to be removably fitted to it. A liquid conveying method and a liquid conveying unit showing an improved liquid conveying efficiency are provided.
Claims8
A liquid conveying apparatus for driving liquid to move in a fluid channel of a micro-fluid device, comprising:
- an oscillator having a plurality of electro-mechanical energy converting devices;
- and
- a signal generator for applying at least two voltage signals to the oscillator such that the at least two voltage signals are (A) synchronized in terms of frequency and phase and (B) amplitude-modulated at one and the same frequency and in different phases.
