The ability to measure multiple sensing points over large intricate surfaces can be a difficult task. Traditionally engineers have used electrical strain gauges to monitor many points over a structure such as an aircraft wing or large composite component. However applying many individual gauges is both time consuming and adds significant weight to the structure in the form of cabling.
