Low-power global navigation satellite system-enabled wireless sensor network for acoustic emission localisation in aerospace components
Structural health monitoring systems for the localisation of acoustic emission (AE) events have been developed in the past few years for aircraft components. However, these systems still require complex and heavy electrical wiring for each sensing device and sophisticated algorithms for the localisation of AE signals, which inevitably increases both weight and costs. This paper reports the creation of a low-power (few hundred mW) and low-weight (~30 g) global navigation satellite system-based wireless sensor network for the identification of AE events in aircraft structures.
