Power Generation From Highway Traffic Using Piezoelectric Sensors & Vertical Axis Turbines

Full Project Description

The Power Generation From Highway Traffic Using Piezoelectric Sensors & Vertical Axis Turbines is an innovative renewable energy project designed to harvest unused energy from moving vehicles on highways. This system combines piezoelectric energy harvesting and airflow-based micro wind generation to produce clean electrical power from everyday traffic movement.

Project Overview

As vehicles move along highways, they generate mechanical pressure on the road surface and strong airflow around them. This project captures both forms of energy and converts them into usable electrical power. The generated energy can be utilized for street lighting, traffic signals, sensors, and IoT-based monitoring systems, especially in remote or off-grid highway areas.

Working Principle

1. Piezoelectric Energy Generation

• Piezoelectric sensors are installed beneath a simulated road surface.

• When vehicles pass over the surface, pressure is applied to the sensors.

• The sensors generate electrical voltage proportional to the applied force.

• Multiple piezo sensors are connected in series/parallel to increase output power.

2. Vertical Axis Turbine Energy Generation

• Mini vertical axis wind turbines are placed beside the road.

• Moving vehicles create airflow that rotates the turbine blades.

• The rotating turbine drives a generator to produce electrical energy.

• This method works regardless of wind direction, making it ideal for highways.

System Components

• Piezoelectric sensors

• Vertical axis micro wind turbine

• DC motor / generator
