Our new paper: “Metal oxide based pH sensors” in Progress In Materials Science
December 27, 2019
We are happy to share our new paper, “Metal oxide based pH sensors” recently published in Progress In Materials Science. 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.
