Abstract

An on-chip micro manometer for measuring local pressure inside a microfluidic network is proposed. The manometer works based on the pressure-induced deformation of PDMS chamber. The pressure at the point of interest is determined by the length of the color bar connecting to the chamber. The length extends when the chamber is squeezed by a negative pressure, and vice versa. The experimental results show that the absolute correlation between the bar length and applied static pressures is up to 0.98. The manometer also successfully captures the dynamic changes of pressure at 0.5, 1, 2, 4 and 8 Hz.
