Australia’s coastal roadways are under stress from overuse and extreme weather events, with many requiring maintenance and upgrades. This type of soft soil construction comes with risks, the management of which geotechnical engineering consultancy Geoinventions Consulting Services is set to transform with the advent of its world-first smart sensor.

Developed in collaboration with Griffith University and supported by co-funding from IMCRC, the sensor harnesses micro-electro-mechanical systems (MEMS) technology and the Internet of Things to measure stress-strain behaviour and soil-infrastructure interaction.

The robust, waterproof and energy-efficient sensor is designed to withstand Australia’s harsh environment, and with its many functions, can do the job of two devices traditionally used in geotechnical engineering.

Barry Kok, Geoinventions’ Operations Director, said, “Thanks to the support from IMCRC and the research expertise from Griffith, we’ve developed and successfully patented a sensor capable of revolutionising traditional geotechnical monitoring, managing risks and improving safety in construction.”

“We’re proud our sensor will be Australian made, with production set to begin this year on the Gold Coast in Queensland. By manufacturing locally, we can offer an alternative to imported sensors, overcoming supply chain delays while providing a cost-effective, high quality, customisable and more advanced product.

“By facilitating industry-led research and development (R&D), IMCRC has enabled us to create a truly innovative product and contribute to the growth of Australia’s sovereign manufacturing capability while doing so.”

Professor Dzung Dao, Head of Mechanical Engineering at Griffith University, added, “IMCRC’s approach to R&D helped shape a close and collaborative relationship between Griffith and Geoinventions, which will endure into the future as we continue to advance the sensor technology.

“Through this project, Griffith’s research has helped solve a real-world challenge for industry, while also advancing Australia’s MEMS manufacturing capabilities and helping to position the nation as a leader in geotechnical sensor technology design and production.”

IMCRC has enabled us to push boundaries – not just by financially supporting this unique project – but by stretching our thinking around applying the technology and connecting us to key people within the industry.
