Road Performance of Common Piezoelectric Transducer for Asphalt Pavement Energy Harvesting

Abstract:

The discussion in the paper is focused on energy transition efficiency, stiffness and intensity of common piezoelectric transducers in the following aspects. Firstly, we have found out that bridge piezoelectric transducers possess high energy transition efficiency and the similar stiffness to asphalt pavement through comparing and analyzing road performance of several common piezoelectric transducers. Thus, we hold the view that it is applicable for energy collection of asphalt pavement and will be analyzed subsequently. Secondly, we have analyzed energy transition efficiency and stiffness characteristics of arc bridge piezoelectric transducer and rectangular bridge piezoelectric transducer in laboratory test. The results show that, under the same load stress, arc transducers are better than rectangular transducers in terms of energy transition efficiency; but comparing with rectangular transducers, arc transducers are more prone to be destroyed, which is not helpful for bearing traffic load.
