- Abstract
We describe and discuss an integrated Li-ion sensor device combining a LiFePO4 thin film prepared by pulsed laser deposition as sensing electrode and a modified ferrocene-based grafted electrode working as pseudo-reference; both were deposited onto a specific optical lithographed substrate. The simple procedure consists first of a coupling reaction at RT to form the molecule, which is grafted through a 4-h reaction with a gold substrate. Preliminary potentiometric measurements were first carried out versus a composite Bellcore electrode of Na0.33MnO2/C, and then with thin film electrodes of LiFePO4 for the detection of Na+ and Li+ ions demonstrating the validity of the approach using both technologies.
