PCB design for CNT-FET Gas Sensor Array
In our project, the objective is to detect nitrogen dioxide gas (NO2) through Carbon Nanotube (CNT) gas sensor array by repeatedly measuring the transfer characteristics of the CNT-FETs (Field Effect Transistors) in the array. However, achieving sensor recovery poses a challenge, necessitating the application of high voltage pulses at regular intervals to heat the channel and desorb gas molecules (self-heating). Our current measurement mode face challenges in independently controlling and tuning the voltages for each device. This project aims to develop a new PCB design that addresses these challenges.
