Volume sensors, medical applications

As pointed out earlier, microfluidic systems have a wide range of applications, e.g. heat exchange systems for electronic devices [28-31], medical diagnostic and analytical chemical applications [69, 70], and precision dilution systems with minimal dead volume for gas chromatography [71]. More may be anticipated as the technology matures. Current research at many laboratories has shown the need to provide flow control at extremely low levels for sensor-controlled implanted drug delivery systems [72] and portable diagnostic cards for polymerase chain reaction analysis [73]. 

The flow sensor is at the core of volume flow controllers used in air-conditioning. These controllers are important components in modern HVAC applications. They measure, analyze, and control room-air flow in order to supply air in defined quantities to entire buildings or individual rooms. Other target markets for this flow sensor include test facilities, gas handling, and medical technology.
