Fossil fuels are the main source of energy which may deplete in the future. Moreover, they causes climate change issues, greenhouse gas emission and consequently, global warming. Increasing use of renewable energies is suggested as a solution in response to sustainability concerns. Harvesting walking energy is a sustainable method that converts wasted energy of body into electric power. There are different types of mechanism for walking energy conversion that this paper focuses on piezoelectric transduction. The study aims to estimate the output power of piezoelectric system within the pavement when people step on it. The case study is selected as a research design. Non-participant observation and survey was conducted at the KLCC-Pavilion pedestrian bridge as a case study. Firstly, the number of footsteps along the walkway was counted to estimate the output power. Moreover, a survey was distributed among the pedestrians walking along the walkway in order to understand the respondents opinion about using this technology and obtain the average weight of the pedestrian, as well. Then, estimated output power calculated and theoretically investigated. The results show that the number of footsteps at the case study is sufficient to provide electricity for lighting system of walkway at night. The experimental design and test of the model is recommended.
