Abstract: An effective energy generator deployed to the power conditioning for wireless sensor network adopted for aircraft health monitoring. This harvesting system captures energy from its environment. Here, two types of energy are used (thermal gradients and vibrations) and stores this energy in super capacitor. This paper presents recent developments in energy and these technologies for structural health monitoring applications. It also has a capability of harvest energy even when thermal gradients have disappeared and one of the major considerations is using of ultralow power converter. The simulation of the proposed system and validation of results is carried out in the MATLAB/SIMULINK software environment.

Keywords: Energy harvesting, Wireless sensor network, thermal gradients.
