https://doi.org/10.1016/j.pmatsci.2019.100635

This article presents an in-depth review of the wide range of Metal oxides (MOx) materials that have been utilized to develop pH sensors, based on various mechanisms (e.g. potentiometric, conductimetric, chemi-resistors, ion sensitive field effect transistor (ISFET) and extended-gate field effect transistor etc.). Concerning materials and design of sensors for various practical application, the major challenges are toxicity of materials, interference of other ions or analytes, cost, and flexibility of materials. This review also discusses the metal oxide-based composite sensing (active) material, designs of pH sensors and their applications in flexible/wearable biosensors for medical application are examined to present their suitability for these futuristic applications.
