N2  - Capacitive sensors based on interdigitated array electrodes (IDAEs) integrated into microfluidic channels have been developed for many bioanalysis applications due to its advantages in comparison with electrochemical sensors. In this study, an IDEAs capacitive sensor has been proposed, fabricated and
characterized. The IDEA structure is fabricated in a 100 ?m-width microfluidic channel using
micromachining technology. Electrical impedance spectroscopy measurements of the sensor have been carried out in a wide frequency range from 10 kHz to 1 MHz. Performance of the IDEAs sensor has been demostrated through sensing the concentration of the phosphate buffer saline (PBS) which is fully filled
in the microchannel. The obtained results show a linear relationship between the measured conductance and concentration of PBS solution, demonstrating the possibility of estimating conductance of the solution through the total impedance.
