Sharath Bhagavatula currently works on electrokinetic characterization of hydrophobic surfaces for microfluidic devices. In microfluidic systems, fluid movement is often controlled using electric fields - how the fluid reacts to applied electric fields depends upon the electrokinetic interaction between the substrate and fluid. The goal of Sharath's project is to develop an understanding of this electrokinetic relationship in hydrophobic substrates. The research has specific implications for microfluidic devices used in biomedical analyses and diagnostics.

More specifically, Sharath has helped develop an automated phase-sensitive streaming potential measurement device to determine the electrokinetic properties of a fluid/substrate interface; he currently uses this system to take measurements in hydrophobic systems.


Sharath Bhagavatula joined the Micro/Nanofluidics Laboratory in May, 2006. He is currently a senior in the department of Electrical Engineering at Cornell.

Current Projects

Current projects include the electrokinetic characterization of hydrophobic surfaces such as Topas and Zeonor using the streaming potential measurement technique.
