We present a lateral cavity acoustic transducer (LCAT) capable of pumping and mixing fluids within a microfluidic system using an acoustic energy source from an external piezoelectric buzzer. The device is capable of pumping at flow rates of approximately 250 nl min(-1) and real-time mixing in low flow rate (<1 microl min(-1)) devices typical in microfluidic systems.

UI MeSH Term Description Entries
D000162 Acoustics The branch of physics that deals with sound and sound waves. In medicine it is often applied in procedures in speech and hearing studies. With regard to the environment, it refers to the characteristics of a room, auditorium, theatre, building, etc. that determines the audibility or fidelity of sounds in it. (From Random House Unabridged Dictionary, 2d ed) Acoustic
D044085 Microfluidics The study of fluid channels and chambers of tiny dimensions of tens to hundreds of micrometers and volumes of nanoliters or picoliters. This is of interest in biological MICROCIRCULATION and used in MICROCHEMISTRY and INVESTIGATIVE TECHNIQUES. Microfluidic
