Being able to precisely measure pressure in microfluidic devices is crucial for lab-on-chip applications, as it is required for flow control, monitoring and fluid characterization. However, such measurements face specific challenges as far as integrability and coupling to liquid phases are concerned and commercially available pressure sensors often lack the precision required. We have developed a chip-integrated liquid-based pressure sensor using a color switching hydrogel and have proven that it can resolve pressures as low as 20mbar with a resolution of 10mbar.

In this project we propose to develop a reliable stand-alone optical pressure sensing unit, to be connected in a non-invasive way to various microfluidic devices. To tune the accessible pressure range and resolution we will address the complex mechanical interactions governed by gel properties, device design and fluid flow. At the same time, the readability of the color response and the sensor calibration will be simplified. A versatile sensor will be developed, of interest to microfluidic companies working in fluid control, biotechnologies or pharmaceutics.
