ABSTRACT: The growing impact of airborne pollutants and explosive gases on human health and occupational safety has escalated the demand for sensors to monitor hazardous gases. This paper presents a new miniaturized planar electrochemical gas sensor for rapid measurement of multiple gaseous hazards.The gas sensor features a porous polytetrafluoroethylene substrate that enables fast gas diffusion and a room-temperature ionic liquid as the electrolyte. Metal sputtering was utilized for platinum electrode fabrication to enhance adhesion between the electrodes and the substrate. Together with carefully selected electrochemical methods, the miniaturized gas sensor is capable of measuring multiple gases including oxygen, methane, ozone, and sulfur dioxide that are important to human health and safety.Compared to its manually-assembled Clark-cell predecessor, this sensor provides better sensitivity, linearity, and repeatability, as validated for oxygen monitoring. With solid performance, fast response, and miniaturized size, this sensor is promising for deployment in wearable devices for real-time point-of-exposure gas pollutant monitoring.
