| Abstract: | A new method for transporting digital micro-fluids among multi chips has been proposed based on surface acoustic wave(SAW).It is composed of three piezo-electric chips: one is an interface chip and the others are working chips.Each chip has an interdigital transducer(IDT) with 27.5 MHz center frequency and a reflector,which are fabricated on 1280YX-cut lithium niobate(LiNbO3) substrate.A digital micro-fluid to be transported was first pipetted onto the working chip 2 by a micro-syringe.After the interface c... |
