• Abstract:
  A novel piezoelectric transducer was designed and fabricated to demonstrate energy harvesting from traffic-induced loading on pavement. The piezoelectric transducer is based on the “cymbal transducer” design used for underwater acoustic and sonar. A novel surface electrode pattern increases energy density and steel end caps enable mechanical coupling through matched stiffness to the pavement. Multi-physics simulation with finite element modeling was used to optimize the geometric design of transducer considering failure stress criteria and maximum energy output. Sixty-four lead zirconate titanate (PZT) Type 5X (Sinocera, PA) square plates with 32-mm width and 2-mm thickness were fabricated into transducers with alloy steel end caps. Sixty-four piezoelectric transducers were assembled in 4 layers of 16 transducers each, inside of an energy-harvesting array. The prototype energy harvesting array was tested using a pneumatic system to simulate vehicle loading. The output energy of the prototype module was 0.8 mJ at 60V from a 600 lb load. Under continuous loading of 500 lb at 5Hz, the power output was 2.1 mW. Using a DC-DC step down converter, the output power was used to illuminate a string of LEDs.
