Design and Development of Energy Harvesting Ramp Through Brushed DC Generator Using Gear System

In the recent years, obtaining a sustainable form of energy to power various autonomous wireless and portable devices is increasingly becoming a matter of concern & various alternate sources of energy have been explored. Energy harvesting technology may be considered as the ultimate solution to replace batteries and provide a long-term power supply for portable devices. The aim of this project is to design and construct a ramp that harvests the kinetic energy from vehicular impacts. The design consists of six stages which include gear mechanism, dc generator, boost converter, transistor circuit, battery level indicator and inverter. The designed prototype is functional, durable, economical, and feasible using affordable components that are readily available in the market.
