-The ability to reliably detect, assess and predict damage in critical aerospace, civil and mechanical structures is key to ensuring their safety and long-term maintainability. +The ability to reliably detect, assess, and predict damage in critical aerospace, civil and mechanical structures is key to ensuring their safety and long-term maintainability. 
  
-Though effective, traditional non-destructive evaluation (NDE) methods involve the use of bulky equipment that makes automation and real-time, on-demand evaluations impossible. Furthermore, the growing prevalence of composite materials such as carbon fiber reinforced polymer (CFRP) in aerospace engineering is driving a shift from the schedule-based monitoring and maintenance methods towards condition-based methods due to the complex failure modes that these composite materials exhibit. +Though effective, traditional non-destructive evaluation (NDE) methods involve the use of bulky equipment that makes automation and real-time, on-demand evaluations impossible.

 +Guided-wave structural health monitoring (SHM) enables the addressing of these challenges by employing networks of piezoelectric-sensors that are embedded within the structure under test. Ideally, the actuation and data acquisition electronics accompanying these embedded sensor networks should have a compact form factor that enables localized data collection and consolidation before communicating with the centralized processing unit that executes higher-level functions. However, despite advances in the sensors, the accompanying electronics have remained relatively bulky thereby greatly limiting the deployment of real-time, on-demand guided wave SHM.
