Abstract
An acoustophoresis device having a sample vessel and a piezo transducer is described. The sample vessel has an outer surface, a microchannel within confines of the outer surface, a first port extending through the outer surface to the microchannel, and a second port extending through the outer surface to the microchannel, such that a blood sample is insertable through the first port into the microchannel. The sample vessel has conductive traces on the outer surface. The piezo transducer is bonded to the outer surface of the sample vessel to form a monolithic structure. The piezo transducer contacts at least one of the conductive traces, the piezo transducer is configured to generate ultrasonic waves inside a sample in the microchannel. The piezo transducer has an excitation signal input and response signal output electrically connected to the at least one of the conductive traces.
