Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Pavement material is an important factor for creating a pedestrian and environmentally friendly walkway. Generally, kinetic energy of footstep during walking is mostly wasted, while, this energy can be harvested and converted to electrical power. This study aims to use piezoelectric materials within pavements in the form of tiles. The kinetic energy of walking is harvested through piezoelectric mechanism. The study proposed a pavement consisting of piezoelectric sensors. Flexible and green material are selected as the top layer of the pavement. The scaled prototype is fabricated according to the mechanism of walking. The pavement is tested in terms of voltage generation in different arrangements. The results show that in order to harvest the optimum energy of walking, the piezoelectric sensors need to be covered with a conductive layer such as a steel sheet. Also, it is found that covering the piezoelectric materials with a hard surface leads to load distribution over the sensors when stepping on it which subsequently, generates more voltage. Moreover, when the piezoelectric pieces are placed in an alternative arrangement, more voltage is generated. It can be concluded that the arrangement of the piezoelectric sensors and their connection to the conductive layer are important factors in harvesting the optimum walking energy. The study recommends that pavement equipped with piezoelectric material is a promising method to generate electricity when implemented in crowded areas.
