Piezo electric sensors for monitoring airport surface movement — A sustainable airport ground traffic management system

This paper outlines the operation principles with the piezo electric sensors for airport surface movement control. This type of sensor enables one not only to essentially reduce power consumption to a level acceptable by sustainable sensor network, but also to perform moving object detection on voltage impulse created by pressure from moving objects, as well as to perform automatic classification of objects according to their weights, speed and direction of movement. The preliminary result of experimental tests on piezo thin film sensor, which is light weight and bears similar physical properties as piezo electric sensor, confirms the predicted operation characteristics, and shows the applicability of piezo electric sensors for monitoring airport surface movement.
