Microfluidic channels with integrated ultrasonic transducers for temperature measurement and method |
摘要 |
There is described a method and apparatus for measuring temperature of a fluid in a microchannel of the type having spaced walls. An ultrasonic transducer transmits ultrasonic waves transmitted from one wall to the opposite wall. A processor determines the time-of-flight of the ultrasonic waves from the one wall and reflected to the opposite wall to the one wall. The processor converts the time-of-flight to velocity by dividing the distance between walls by the time-of-flight. The processor converts velocity to temperature from the relationship of velocity to temperature in the fluid.
