The increasing demand for electrical energy and the environmental impacts of fossil fuel consumption encourage the exploration of renewable and alternative energy sources. One potential source of renewable energy is the mechanical energy generated from human activities such as walking. This study aims to design and develop a prototype device capable of generating electrical energy from footstep pressure by applying the principle of electromagnetic induction based on Faraday’s Law. The prototype consists of a stepping platform equipped with springs, a coil system wound with enamel wire, a permanent magnet, and a measurement unit using a galvanometer. When a person steps on the platform, the spring mechanism causes the magnet to move relative to the coil, producing a change in magnetic flux that induces an electromotive force. Experimental observations indicate that faster oscillations of the spring result in larger galvanometer deflections, indicating higher induced current. The results demonstrate that the prototype successfully converts mechanical energy from footsteps into electrical energy. This device has potential applications as a small-scale renewable energy generator and as an educational tool for demonstrating electromagnetic induction principles.
