| Abstract | This paper explores the applicability of human kinetic energy in charging portable devices. Piezoelectric sensors are installed in a walkway or a mat where mechanical energy of footsteps is converted into electrical energy. This energy once harvested goes through a number of electronic elements such as power conditioning circuits together with amplifiers in order to generate the right voltage and worth of current required in charging portable gadgets. The system consists of an inverting amplifier, a buck converter, an LCD display, a microcontroller, an ADC, a piezoelectric sensor and a battery. The piezoelectric sensor applies a voltage when pressure is exerted such as that which occurs when someone is walking. The ADC samples the voltage and converts it into a digital signal; the microcontroller then processes it. The microcontroller monitors battery charge, charges batteries when necessary and displays related information on the LCD. This way the voltage of the battery is regulated by the buck converter to an ideal voltage suitable for charging mobile devices. The suggested strategy is an innovative and efficient means of charging mobile devices in the public domains and other busy centers. This makes this technology to enhance the future to be more sustainable and green by using power from renewable resources and by reducing the extent to which it depended on conventional outlets.While the core concept of piezoelectric energy harvesting from human footsteps is promising, several challenges and considerations need to be addressed for widespread implementation: Efficiency and Power Output: Improving the geometrical configuration and the material properties to achieve the highest efficiency from the sensors. Searching for potential new circuit configurations able to reduce power losses at the period of energy conversion and storage. Based on such aspects like flow of feet traffic, the load balance, and environment conditions to improve the system efficiency.Durability and Reliability: Designing safe structures that will not wear out easily that can easily be applied in areas that are torn and crowded. Adopting that suitable parts should be used for the design and use of strong packages to facilitate long-term functions. Cultivating approaches on how to prevent much downtime or avoid shortening the lifespan of systems much.Cost-Effectiveness: Economies of scale and product with regards to manufacturing cost could be addressed. Identifying potential for application of less expensive materials and elements without luxating performance. Knowing where to get funds for the training program and other incentives provided by the government to scholars and researchers. Parking lots and garages will be handy to charge electric cars, for instance, by means of an external wall or through wired connections. To supply power to the sensors and the communication equipment in various smart cities. Residential and Commercial Buildings: For charging small power devices such as lighting, security systems and other low power gadgets in our homes or offices.Producing power supply in central zones. Wearable Technology: Energy for smartwatches, fitness trackers, and other wearable electronic appliances. Delaying time between recharging and also improving battery longevity. Remote and Off-Grid Applications: Supplement power for recommended electric appliances in areas where power supply is very rare. Promoting and implementing sustainable development while enhancing the living standards of the people that are off the grid. © 2025 IEEE. |
