In this communication, the 3D heterogeneous integration of miniaturized communicating modules used for wireless
network application is described. These communicating objects present the particularity of being in Nano-scale
range. In fact, each object is composed of Nano-sensors, transceivers and E/R antenna. Such investigated ways of
Nano-system integration will allow the development of sensor communicating modules which can be inserted and
located in areas with access difficulty (in particular in non planar area) or even in inaccessible places. This attractive
integration concept is discussed and illustrated here.
The deployment of Wireless Sensors Network for Structure Health Monitoring will allow better
maintenance of the aircraft and predictive diagnosis of the aircrafts in a long term approach. This paper
presents our research on the design of wireless communicating nano-objects for Structure Health
Monitoring in the aircrafts and the improvements bring by the nanotechnologies. The main challenges we
address here are the design of ultra low power communicating circuits to enable high lifetime for the
communicating nodes and their integration on flexible substrate to allow their deployment in difficult
accessible places on the aircraft using conventional technologies. Other main issues are the choice of the
communicating frequency which will allow a high number of communicating nodes in such a small area
like the cabin of an aircraft and the choice of the network architecture.
