A sensor invented by Purdue University, that allows concrete to “talk,” can significantly reduce construction time, the need for repairs, and carbon emissions. The REBEL Concrete Strength Sensing System, developed by WaveLogix, is on track to hit the market this year, and has already been named one of Fast Company’s Next Big Things in Tech for 2022. Discover how this sensor technology is revolutionizing the U.S. interstate system.




Researchers at Purdue University have developed sensors that when embedded in concrete pavements can allow the material to ‘talk’ to engineers to improve road sustainability, reduce traffic delays and cut the carbon footprint of the pavement.

The sensors give more precise and consistent data about the strength and condition of the concrete than existing tools and methods. More than half of US states with concrete interstate pavements have signed up to participate in a Federal Highway Administration pooled fund study to implement the sensors.

The technology, which is set to hit the market later this year as the REBEL Concrete Strength Sensing System, is a product of WaveLogix, which was founded by Purdue researcher Luna Lu to manufacture the technology on a larger scale.

The company licenses the technology from the Purdue Research Foundation Office of Technology Commercialization, which has applied for patent protection on the intellectual property.The sensors were recently named as one of Fast Company’s Next Big Things in Tech for 2022 and were also selected by the American Society of Civil Engineers as one of its “Gamechangers” for the year.

The technology allows engineers to monitor the fresh concrete and accurately measure many of its properties, thus reducing the need for time-consuming laboratory tests. It could also cut down on carbon emissions as it reduces the time vehicles spend waiting in traffic around construction sites, and the amount of cement required in concrete mixes.
