The goal of this project is to design and fabricate a low power, low cost electrochemical sensing system to monitor the quality of water. A three-electrode electrochemical sensor will perform amperometry and cyclic voltammetry and send the captured voltage signal into the analog front end module. The analog signal is amplified, digitized, and transmitted wirelessly off chip. On chip processing provides calibration and control.
This is a design project led by the Mixed-Signal Analog Circuit Sensor Design group MLAB from University of Tennessee Knoxville. We have worked with five undergraduate students from the EECS department designing an Electrochemical Sensor chip to monitor water quality.
