Abstract

A microfluidic pressure sensor may include a reference chamber, a sensed volume, a microfluidic channel connecting an interior of the reference chamber to an interior of the sensed volume, a volume of liquid contained and movable within the microfluidic channel while occluding the microfluidic channel and a sensor to output signals indicating positioning of the volume of liquid along the microfluidic channel. Positioning of the volume of liquid along microfluidic channel indicates a pressure of the sensed volume.
