Microfluidic channel schematic and chip layout used for investigating the relationship between a microfluidic device’s pressure drop and flow rate. (A) Cross-sectional schematic representation of the microfluidic channel with dimensions: length (L), width (W), and height (H) made of Si covered with SiO2 and glass. (B) The chip layout shows different microchannel configurations used in the experiments, varying lengths (L) and widths (W).
