The project is aimed at developing a technology which enables conversion of mechanical energy, imparted on pavement surface by traffic loads, into electrical energy .
The conversion is carried out using piezoelectric generators (PEGs), which are embedded at a depth of 4-5 cm below the asphalt pavement surface. They are placed along the wheel path, so that they are loaded with significant mechanical load.
The generators form a strong power station that can be connected to the local grid. For local projects enough electricity can be produced while using only a few generators. Electricity can also be used for battery charging.
This project is a joint project of the INRC and INNOWATECH Co. A spin-off of this technology is a development of the I-WIM which is an weigh in motion system based also on embedded piezoelectric generators . The I-WIM provides, besides energy production, data on type of the vehicles according to their weight at any speed and the speed of each vehicle.
