Airborne Molecular Communication Using MOS Sensors under Controlled Airflow

This paper introduces an experimental platform for airborne molecular communication (AMC) and investigates the feasibility of using metal oxide semiconductor (MOS) sensors as receivers. The platform enables chemical communication with volatile organic compounds (VOCs), specifically ethanol and acetone, under repeated dosing patterns with controlled airflow. Preliminary experiments show that ethanol and acetone yield different sensor responses, indicating the potential of MOS sensors to facilitate the decoding of molecular signals. Distinguishable temporal response patterns are also shown, highlighting the possibilities and challenges of selective chemical detection in AMC. Future work will extend the study to molecular mixture signals.
