Abstract

In this project, we developed a process to integrate microfluidic channels on standard radio- frequency (RF) A 10.56 GHz RF microstrip interferometer was fabricated using the proposed technique and used to compare electrical responses for liquids with various dielectric properties and thereby demonstrate the capability of RF PCB-integrated microfluidic devices for biological sensing. Microchannels were milled into a substrate and prepreg outlines for microchannels were cut using a laser system. Substrates were adhered and bonded by clamping and baking. The RF interferometer responded to changes in liquid permittivity with high sensitivity relative to many other types of dielectric sensors.
