Wavelogix has secured a $500,000 Phase IIB Small Business Innovation Research (SBIR) grant from the National Science Foundation's Directorate for Technology, Innovation and Partnerships to advance its concrete sensing technology and facilitate integration with digital twin systems for real-time structural monitoring. The initiative, which began in March 2026 in West Lafayette, Indiana, extends a previous Phase II award and is scheduled to conclude by December 2026. Funding will support the development of cost-effective, durable concrete sensors, interoperability standards, scalable data pipelines, and data governance frameworks. These efforts aim to connect in-situ sensor measurements to digital twins compatible with BIM and asset-management platforms. Industry analysts note that this work may drive broader adoption of IoT-enabled concrete monitoring throughout the infrastructure sector.
Background
Wavelogix, a Purdue University spin-out, developed the Rebel concrete strength sensing system, which deploys piezoelectric sensors embedded in fresh concrete to capture real-time strength and temperature measurements. Invented by founder Luna Lu, the technology has received multiple honors, including AASHTO T-412 approval, a gold Edison Award, the Alfred Noble Prize, and recognition in Time's Best Inventions of 20231Blog - Wavelogix. The SBIR grant aligns with NSF's broader initiative to support digital twin technologies through investments in real-time sensing, data assimilation, modeling, and decision-making frameworks2Digital twins: Virtual models with real-world impacts | NSF - U.S. National Science Foundation.
Details
The Phase IIB SBIR grant will fund engineering advancements and scale-up manufacturing of the Rebel sensor system for broader commercial adoption, according to Wavelogix CEO Joe Turek3Concrete sensor manufacturer Wavelogix receives $500K grant from National Science Foundation - News. Luna Lu indicated that the grant will shift concrete verification from reactive testing to proactive, real-time assessment3Concrete sensor manufacturer Wavelogix receives $500K grant from National Science Foundation - News. The project includes establishing best practices surrounding data governance, setting sensor interoperability standards, and building scalable data pipelines to deliver actionable sensor data to digital twin systems integrated with BIM and asset-management platforms.
The Rebel system has been deployed across more than 200 sensor installations at over 60 construction projects in 17 states, including bridge decks and pavements, between July 2023 and October 20244| | --- | --- | --- REBEL® Concrete Sensor Test.

Outlook
Upon completion in December 2026, the Phase IIB project could enable pilot deployments in key infrastructure types such as bridges, tunnels, and high-rise buildings. Embedding sensors in concrete structures may allow digital twins to support proactive maintenance, enhanced safety monitoring, and optimized lifecycle costs. Successful integration with BIM and asset-management workflows is expected to influence the pace and scale of wider industry adoption.
