DEVICE AND METHOD FOR SEPARATION

摘要

The present invention provides a device and a method for separating particle s from fluids using ultrasound, laminar flow, and stationary wave effects comprisinga micro-technology channel system with an integrated branching poi nt or branching fork, and a single ultrasound source. One of the characteristic s of the invention is that the single ultrasound source, which generates the standing waves, excites the complete structure including the channel system. No special reflectors or the like are needed. Extremely thin dividers can separate the flow, thereby enhancing the effectiveness of the device. The device could be manufactured in silicon and the ultrasound energy could preferably be delivered by a piezoelectric element.
