【 摘 要 】

A miniaturized sensor operating in Radio Frequency region (RF) is proposed to address the need in picoliter liquid characterization. The sensor is based on a coplanar waveguide (CPW) combined with a microfluidic channel dedicated to microliter liquid characterization with perspectives for biology and single cell characterization. Using microtechnology process, the sensor has been designed on a 0.5 mm thick quartz wafer with Cr/Au electrodes. A prototype of the sensor has been fabricated and evaluated with ethanol/water mixtures at different molar fractions of ethanol. A good agreement between theoretical and measured electrical response of the sensor is observed.
