Totally integrated microengineered ion sensors for large-scale applications

Objective

The overall objective of the project INION is the development of the IC compatible technological basis for pilot manufacturing and further mass-production of a new generic type of ion sensors: Ion-Selective Conductometric Microsensors (ISCOM). The ISCOM requires no reference electrode, has a single-probe, all-solid-state construction. These sensor design features will allow for the first time complete manufacturing of integrated ion sensors using only IC technology compatible fabrication processes.

The manufacturing processes for ISCOM-based sensor systems will be optimised and appropriate sensor materials will be manufactured and tested. Special attention will be paid to specific requirements in materials, resistance to hostile environment, manufacturability and compatibility between different foundry processes. Dedicated interface electronics will be developed and tested.

The project will culminate in a pilot fabrication of the sensors in a small series for field tests.

Public and private bodies responsible for public hygiene and health and all sectors of industry, require accurate, reproducible, stable and low-cost ion sensors to enable real-time monitoring of water quality and industrial effluents on a large scale. In healthcare the low-cost ion sensors would have direct impact on the development of nearpatient monitoring techniques.

The potentiometric measuring cells currently used in ion monitoring apparatus must comprise an electrochemical reference electrode that requires artisanal manufacturing and is of a macroscopic size. Failure to design a microelectronics technology compatible reference electrode prevents mass-production of ion sensors and decreases their application scope. This compromises the recent progress achieved in emerging microsystem technology and in miniaturisation of analytical instrumentation.
