Abstract
An integratable fluid flow and property microsensor assembly is configured to be operably embedded in a microfluidic cartridge of the type used in lab-on-a-chip systems. The assembly is a robust package having a microstructure flow sensor contained within a housing in order to achieve a robust sensing device. The cartridge provides a flow path to the assembly, which directs the fluid across the flow sensor and returns the fluid to the cartridge flow path. The flow sensor monitors the controlled flow of fluid and transmits signals indicative of that flow. The assembly structure provides a robust sensor that is operable and accurate in many different applications.
