Abstract : This work deals with energy harvesting and storage to power aircraft embedded wireless sensors. First, we discuss the issue of powering wireless sensors in an aircraft and we present a state of the art of the various energy harvesting and storage technologies that could be used. Then, through the design and construction of two harvesters, we show the possibilities offered by this technology and we explain the design constraints imposed by the application to get a reliable and robust power supply. The first harvester is a photovoltaic power supply located on the upper surface of an A321’s wing supplying a wireless sensors belt nearby. The systems provides 2 watts to the load, works with cloudy weather and is highly resistant to negative temperature (-50°C) and low pressure (200hPa) that are met at aircraft cruising altitude. The second harvester is a thermoelectric power supply located in an A380 pylon supplying a structural health monitoring system. The harvester is highly resistant to high temperature (300°C) and severe vibrations of the installation area and manages to generate the required energy to supply the structural health monitoring sensors. Mechanical and electronic design steps and choices that led to both harvesters are detailed and discussed.
