Abstract

The present invention provides fluidic devices and systems which have micromachined ultrasonic transducers integrated into microchannels. The ultrasonic transducers generate and receive ultrasonic waves. The transducers can be disposed and operated to measure fluid characteristics such as pressure, density, viscosity, flow rate and can also be used to mix and pump fluids.
