Israeli researchers have modified a machinery-monitoring technique employed in the Air Force to suit medical applications. As a result, the approach could someday take off in terms of evaluating and improving orthopedic implant design.
To determine whether a system could benefit from preventative maintenance, the Israeli and American air forces often use a method called ferrography. This technique entails the extraction and analysis of tiny iron particles—hence the name—from lubricants such as oil and grease that can indicate wear in machines.
