Generally, pedestrian walkway are designed to provide an accessible and safe path for people who prefer to walk. The walking activity can benefit both people and society in term of health and environment conservation through reducing usage of vehicle transpiration. Hence, the pedestrian walkway can serve more than providing a safe path and are potential to be an energy efficient space. This study aims to review renewable energies exist in pedestrian walkway spaces. Therefore, two sources of walking energy and solar energy is selected and harvesting technologies are investigated. Among the different mechanism piezoelectric transduction is selected and fundamentals and circuitry are discussed. The results show that in order to harvest optimum energy, arrangement of harvesters is an important factor. Moreover, system sizing is important in the design of hybrid renewable energy system. © 2021, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
