Lateral cavity acoustic transducer

Armando R. Tovar and Abraham P. Lee

---

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 µl min^-1) devices typical in microfluidic systems.
