An improved the impedance spectroscopy measurements with non-contact microelectrodes embedded into a flexible polymer comprising a microfluidic network

Résumé

Two coplanar carbon microelectrodes were coated with the polymer by using a photoablation procedure in order to avoid any faradic reactions in the fluidic channel. In fact, only the dielectric properties of microelectrodes/ polymer/ fluidic channel interface are taken into consideration. This paper develops an analytical model that permits to predict the best frequency range to be selected for real-time contactless microchannel resistance changes. The non contact electric impedance spectroscopy is promising for new generation of sensor or biosensor applications on miniaturized flexible or patch polymer devices.
