Abstract
A micro-fluidic device and methods for measuring one or more rheologic properties of a fluid. The micro-fluidic device includes a substrate and at least one cover bonded to a surface of the substrate with a fluid channel formed in at least one of the cover or the substrate. Further, the micro-fluidic device includes a first differential pressure gauge that can have a first differential pressure sensor in fluid communication with both a first pressure site and a second pressure site. Further still, the micro-fluidic device includes the first pressure site and the second pressure site that can be spaced apart by a first section of the fluid channel. Also, the micro-fluidic device includes a data processor communicatively coupled to the first differential pressure sensor, so as to receive data generated by the first differential pressure sensor.
