Abstract:
Ion sensor based on differential measurement comprising an ISFTET-REFET pair wherein the REFET is defined by a structure composed of an ISFET covered by a microreservoir where an internal reference solution is contained. The sensor comprises a first and a second ion-selective field effect transistor, an electrode, a substrate on the surface whereof are integrated the two transistors, connection tracks and the electrode and a structure adhered on the first ion-selective field effect transistor which creates a microreservoir on the gate of said first transistor, with the microreservoir having a microchannel which connects the microreservoir with the exterior and the microreservoir being filled with the reference solution.

Claim (Index 20):
An ion sensor based on differential measurement comprising:\n a substrate whereon are integrated connection tracks; an electrode of a conductor material arranged to be in contact with a solution to measure; a first ion-selective field effect transistor and a second ion-selective field effect transistor electrically connected by the connection tracks to an ion measurement system, each of the first and second ion-selective field effect transistors being fixed on the substrate and having a gate; a structure coupled only on the first ion-selective field effect transistor configured to create a microreservoir on the gate of the first ion-selective field effect transistor, wherein the gate of the first ion-selective field effect transistor is arranged to be in contact with a reference solution and the gate of the second ion-selective field effect transistor is arranged to be in contact with the solution to measure; and at least one microchannel connecting the microreservoir with the exterior of the ion sensor through an outlet orifice of the at least one microchannel, the at least one microchannel configured to calibrate the ion sensor by filling or renewing the microreservoir with the reference solution and comprising a first longitudinal section.
