Investigation and development of novel solid-state potentiometric pH sensors

Project Outline

Measurement of pH is an important parameter in environmental, industrial and biological processes. A glass electrode is the most accurate instrument for pH measurement, however, it is brittle, susceptible to matrix effects and not possible for miniturisation.To overcome these issues of glass electrodes, various metal oxides and metal nitrides have been investigated and proposed as potential electrode materials as pH sensors. Therefore, this project involves development and study of various novel metal oxides and metal nitrides thin films as an alternative to glass pH electrode.
