Paper Abstract

Road pavements spread in large areas and convey various energy sources possibilities such as high thermal gradients due to its materials and colours, wind corridors, large flat areas for solar harvesting as well as heavy loading from traffic. Latest advances in the road energy generation have discretely been implemented and mainly focused on photovoltaic surface applications. This study explored the stresses on pavement surfaces from loading shockwaves that yield to the vibration of a cantilever piezoelectric sensor array producing energy to power up a LED raised marker strip to beacon drivers to a high speed paying lane in a tool plaza. The passing vehicles triggered 16 Piezoelectric Sensors divided into four imbedded steel profiles. The peak energy generation obtained in the experiment was 36.1 μW for a continuous loading due to a 6-axle truck. The proposed cantilever array demonstrated high potential for applications, with room to improvements, using natural vibration in the piezoelectric sensors and the experiment continuation
