Microfluidic parallel circuit for measurement of hydraulic resistance [PDF]
Biomicrofluidics, 2010 We present a microfluidic parallel circuit that directly compares the test channel of an unknown hydraulic resistance with the reference channel with a known resistance, thereby measuring the unknown resistance without any measurement setup, such as standard pressure gauges. Many of microfluidic applications require the precise transport of fluid along
