The proliferation of commercial components (COTS) and manufacturing processes along with the combination of low energy computing and wireless communication technology are the foundations in the 00s of interconnected multifunctional smart systems, called Internet of Things enhancing our quality of life (The Economist 2005). The Internet of objects would encode 50 to 100 trillion objects, and be able to follow the movement of those objects (J-B Waldner, 2007).

One way to address the understanding and modeling of complex systems is to develop a distributed instrumentation based on advanced technologies of smart multifunctional sensors, combining low energy computing, versatile architecture and wireless communication with the objective to diagnose weaknesses of the observed system. We focus for many years on the development of methods and technologies for the analysis, identification and localization of vibration signatures and displacements in heterogeneous material or structure for Human or Structural Health Monitoring (HHM & SHM).
