Abstract : This work adresses the issue of energy autonomy within wireless sensor networks embedded in aircrafts, which may be solved through ambient energy harvesting and storage. In a first study, we develop a demonstrator based on thermal gradients energy harvesting, which is designed to supply power to a structural health monitoring system implemented near the engine zone. Thereafter, we introduce a capacitive storage architecture which self-adapts to its own state of charge, aiming at improving its performance in terms of startup time, the energy utilization ratio and under some conditions, the energy transfer. Finally, we report the results of a prospective study on aeroacoustic energy harvesting applied to the relative wind. It is shown that this method exhibits an interesting potential in terms of generated power, then we introduce the design and the realization of an optimized energy management circuit, allowing our technique to supply power to a wireless temperature sensor.
