Power Stair: A Piezoelectric Powered Stair as an Alternative Source of Energy During Emergency Power Outage

This proposal focuses on designing stairs with piezoelectric components that convert footsteps into electricity. It aims to evaluate the energy efficiency, load durability, and cost analysis of the system. This study will use various testing methods, including measuring the energy output for efficiency, to determine whether the harvested power is stable enough to light up LEDs. It will also utilize weight load tests to evaluate the piezoelectric materials’ ability to resist deformation. Furthermore, employing cost analysis will examine whether the technology offers practical benefits relative to its development expense, especially for emergency use. Piezoelectric with the dynamo can give an output of an average power of 58.46W every 10 steps, which is enough to power low-wattage LED bulbs for minimal durations. The durability test showed an average modulus of elasticity is 25.695 N/m², signifying that the materials can endure the mechanical pressure repeatedly without deformation. The total computed cost of the prototype is ₱929, which confirms that the mechanism is feasible and low-cost to build. Overall, the results illustrate that the Power Stair is a durable, cost-effective, and viable emergency saver that is suitable for high-foot-traffic locations.
