Development of Sampling and Measurement Technology for Indoor Particulate Matter Using a Small Drone

抄録

The use of small drones has led to more remote and manpower-saving industrial inspections. Furthermore, they are expected to be applied to environmental surveys of closed indoor spaces. Adding functionality to small drones is subject to payload limitations. We have developed a device to capture aerosols on the propeller surface of a small drone flying over an inspection site. It was demonstrated that the airflow generated by the drone during flight was directed toward the center of rotation of the propeller and collected airborne particulate matter on the air filter on the propeller surface. The collected material was available for individual particle analysis by electron microscopy.
