The technology, developed by a team led by Gary Krutz, professor of agricultural and biological engineering, uses a sensor that is claimed to predict when a tyre or hose is compromised and in danger of breaking up to two weeks in advance.
"Tyres, hoses and seals are subjected to harsh and unpredictable conditions making them susceptible to damage that can cause vehicle breakdowns and accidents and the same concerns can be said for medical hoses like breathing hoses or tubes," Krutz said. "The relative cost to replace a hydraulic hose or tyre before it breaks down is substantially less if it is replaced before it breaks down. More important is the safety factor involved in these situations. Preventing a possible engine breakdown or tyre blowout caused by a failure in the integrity of a product is paramount."
Newell added that the sensor technology shows great promise in detecting similar damage or potential breakage in O-rings and v-belts, helping to mitigate engine failures. The technology has been tested on other components and can be used in rubber products such as vehicle isolators, door and automotive seals and orthopaedic devices.
The technology is already being used in hydraulic hoses. Power management company, Eaton has licensed Krutz's technology for its LifeSense sensing product. When the integrity of a hose is compromised, a report is automatically sent to the user or for repair or replacement. This notification is provided with enough time to replace the hose during planned maintenance and is said to save downtime, clean-up costs, environmental damage and potential injury.
The ‘smart’ sensor technology has been tested on more than 100 different products including shoes, airplane wing composites, boat hulls and sporting goods.
"The potential use of this technology touches nearly every industry," Krutz added.
