A Technical Review on Existing pH Detection and Monitoring Technology for in-Vivo Diagnostic Application

Abstract

Monitoring the pH levels is widely known as an important parameter in the diagnosis, identifying treatment, and determining the state of fertility for mammals (e.g. humans, cattle). Therefore, understanding the sensor technology and the effects and how it is utilized to specific identifiers of bodily pH is needed. This paper will evaluate and compare existing pH sensors and determine which among the sensors can be considered the most appropriate for specific invivo applications. With the data presented it can be concluded that ISFET-based pH sensors are the most appropriate having the biggest advantage of commercial availability.
