A precise pH microsensor using RF-sputtering IrO2 and Ta2O5 films on Pt-electrode

In this study, an easily implemented surface modification scheme is reported employing Ta2O5 membrane which covers IrO2 electrode in response to H+ and eliminating redox species interference. Evidence shows that H+ can pass through Ta2O5 films and react with IrO2/Pt electrodes due to proton–electron...
