Toward Sustainable Smart Cities: Design and Development of Piezoelectric-Based Footstep Power Generation System

Smart cities involve information and communication technology (ICT) as the main features. The Internet of Things and 5G will aid smart sensing gadgets by allowing them to connect quickly and securely. Nevertheless, a significant problem in this industry will always be the requirement for active sensing devices that are self-powered and sustainable sources. Piezoelectric energy-harvesting systems are intriguing prospects for creating smart and active self-powered sensors with a variety of applications in addition to powering wireless sensor nodes sustainably. This paper presents a study on sustainable power generation based on the footstep utilizing a piezoelectric sensor. The harvester is made up of a piezoelectric oscillator that is self-biased to control the transistor’s switching frequency and amplitude in the boost converter. This device enables the controlling of the output DC voltage in a simple manner that does not require any biasing external source. Piezoelectric-Based Footstep Power Generation Systems can play an important role in providing energy to smart cities. This research highlights their contribution towards sustainable smart cities while offering a blueprint for integrating footstep power generation systems into urban infrastructure.
