Pedestrian crossing system for the mechanical energy harvesting using piezoelectric materials

Abstract

In recent years, researchers have been developing solutions to reduce our energy consumption by optimizing existing systems in different ways. Indeed, it is not enough just to create or use renewable energies but we must also not waste the available energy. This and systems are developed to recover unused energy of human body movement, which will be used to power either the equipment itself or another. This paper proposes a pressure-type generator that collects human mechanical energy by stepping, a prototype is already designed and manufactured. The average output voltage can reach to 20.9 V by step for F = 100N,and finally, we did a series of tests to prove that the device can have great power output performance in the low frequency environment of the human foot movement.
