Abstract
Aspects of self-powered weigh-in-motion systems and methods that utilize piezoelectric components for sensing load as well as powering data acquisition and analysis components. In one example, the weigh-in-motion system includes a number of piezoelectric stacks, each stack including a number of piezoelectric elements. Each stack includes one or more top or upper piezoelectric element that provides vehicle sensing data. Each stack also includes a set of piezoelectric elements used for energy harvesting. The sensing piezoelectric elements are connected to a data input of a microcontroller for vehicle classification, while the energy harvesting piezoelectric elements are connected to a power input of the microcontroller.
