Vehicle Classification System Based on Ferroelectric Materials

Vehicle classification taking into account the weight of the vehicle and its number of shafts can be relevant for adequate control of vehicles mobility. Piezoelectric materials can be used to infer both parameters in a reliable manner. Also piezoelectric sensors can be cost-effective. In the present work, we focus our attention in the characterization of a piezoelectric cable, where the piezoelectric active material is PVDF. We show that the piezoelectric cable can be used to classify vehicles and count their number of shafts, using a simply signal processing.
