چکیده
Overloaded vehicles are the primary cause of accelerated degradation road infrastructures. In this context, although weigh-in-motion (WIM) systems most efficient to enforce weight regulations, current technologies require costly investments limiting their extensive implementation. Recent advances in multifunctional composites enabled cost-efficient alternatives form smart pavements. Nevertheless, need for a stable power supply still represents major practical limitation. This work presents novel proof-of-concept self-sustainable WIM technology combining pavements and vibration-based energy harvesting (EH). The feasibility piezoelectric bimorph cantilevered beams harvest traffic-induced vibrations is firstly investigated, followed by demonstration proposed under laboratory conditions. main original contributions comprise (i) development new self-powered data acquisition system, (ii) approach fabrication electromechanical testing piezoresistive composite pavement, (iii) analysis developed EH unit conduct traffic load identification through electrical resistivity measurements pavement. While presented results conclude dense networks or combinations different attain complete self-sustainability, an initial evidence paving way towards low-cost systems.

متن کاملNanotechnology-enabled energy harvesting for self-powered micro-/nanosystems.
Health, infrastructure, and environmental monitoring as well as networking and defense technologies are only some of the potential areas of application of micro-/nanosystems (MNSs). It is highly desirable that these MNSs operate without an external electricity source and instead draw the energy they require from the environment in which they are used. This Review covers various approaches for e...
