The future of CO2 sensing


Brewer Science is to present Printed and Flexible CO2 Sensors Prepared via Different Carbon Materials: A Comparison Study at Carbon 2023 conference in Cancun, Mexico.

Gas sensors are crucial components of intelligent detection systems, which have garnered remarkable interest in the past few decades. Carbon dioxide (CO2) sensors are of fundamental importance in a wide variety of applications including clinical analysis, environmental monitoring, agri-food, and chemical fields. Even though the market potential of CO2 sensors is huge, fabricating a reliable and inexpensive sensor is still challenging.

Screen-printed CO2 sensors using carbon materials offer cost-efficient robust solution

“Following up on our previous work, we proposed a comprehensive study comparing the manufacturing process and sensing performance of screen-printed CO2 sensors using different carbon materials.” states Dr. Jiadeng Zhu, Principal Investigator and Team Lead of Sensor Materials at Brewer Science.

Polyethyleneimine (PEI)/functionalized carbon nanotubes (f-CNTs) (PEI/f-CNTs) and PEI/carbon black (PEI/CB) composites were utilized as the sensing agents for screen-printed CO2 sensors. The manufacturing process and sensing performance of the resultant sensors have now been thoroughly explored and compared with a goal of achieving cost-effective and robust sensors.
