Abstract

This paper presents an analog processor design for ion sensitive field effect transistor (ISFET)-based flow through system and its application in smart living space. The dynamic flow-cell measurement explores more information compared to stationary measurement and is useful in environmental monitoring and electronic tongue systems. The multi-channel floating source readout circuitry has been developed for flow-through analysis of ion sensitive field effect transistor based array. The flow injection analysis system with two different ISFET structures has been investigated by using performance parameters such as sensitivity, uniformity, response time of pH sensing. In addition, a self-tuning multi-sensor water quality monitoring system based on adaptive-network-based fuzzy interference system (ANFIS) learning method is developed. The results can be directly used in drinking water and swimming pool monitoring for improving living space and quality.
