Abstract
An acoustofluidic device includes a substrate and an ultrasound transducer contacting the substrate. The substrate and the transducer combined have a set of acoustic natural system resonances determined by the material and the dimensions of the substrate and the transducer. Each system resonance has a resonance frequency and a resonance quality factor. A microfluidic cavity is provided in the substrate to contain a fluid, the cavity having a set of acoustic natural cavity resonances, each having a resonance frequency and a resonance quality factor, determined by the dimensions of the cavity and the speed of sound in a fluid to be contained in the cavity. The material and the dimensions of the substrate and the transducer are selected so that at least one individual cavity resonance has a resonance frequency corresponding to the frequency of a minimum in an impedance spectrum of the transducer.
