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.

Abstract: A method for forming a unique, environmentally-friendly energy harvesting element is provided. A configuration of the energy harvesting element causes the energy harvesting element to autonomously generate renewable energy for use in electronic systems, electronic devices and electronic system components. The energy harvesting element includes a first conductor layer, a low work function layer, a dielectric layer, and a second conductor layer that are particularly configured in a manner to promote electron migration from the low work function layer, through the dielectric layer, to the facing surface of the second conductor layer in a manner that develops an electric potential between the first conductor layer and the second conductor layer. An energy harvesting component is also provided that includes a plurality of energy harvesting elements electrically connected to one another to increase a power output of the electric harvesting component.

Abstract: An energy harvesting module includes a pendular unit with piezoelectric transducer elastically deformable in bending with a clamped end and a free end coupled to an inertial mass. The transducer includes at least one piezoelectric beam configured into two adjacent arms formed single-piece, with external and internal arms arranged side-by-side. The external arm has a clamped proximal end and a free distal end, and the internal arm has a free proximal end supporting the inertial mass, and a free distal end connected to the distal end of the adjacent external arm. An annular mount surrounds the beam at its proximal end and includes the clamp to which is fastened the proximal end of the external arm. The mount includes, in a central region in the vicinity of the clamp, a cavity inside which the inertial mass carried by the free proximal end of the internal arm can oscillate.
