“…In [2], various aircraft application of wireless sensors and actuators are discussed. Systems that are likely to become available in the short term include cabin control (environment, seat occupancy, seatbelts [3]), tire pressure monitoring [4], structural health monitoring [5] and even in-flight entertainment [6]. For such applications, the approach developed in this paper is based on an energyautonomous sensor node (SN) powered by a thermoelectric energy harvester and operating with a low-power communication protocol that allows optimized duty-cycling operation.…”

Abstract-The combination of ultra-low power wireless communications and energy harvesting enables the realization of autonomous Wireless Sensor Networks. Such networks can be usefully applied in commercial aircraft where wireless sensing solutions contribute to weight reduction and increased ease of installation and maintenance. This paper presents, for the first time, a complete energy autonomous wireless strain monitoring system for aircraft. The system is based on a multi-mode wireless TDMA MAC protocol that supports automatic configuration and a time-stamping accuracy better than 1 ms. The energy supply depends solely on an innovative thermoelectric energy harvester which takes advantage of the changes in environmental temperature during take-off and landing. The system was successfully integrated and passed the functional and flight-clearance tests that qualify it for use in a flight-test installation.

Wireless sensor networks consist of physically distributed autonomous sensor nodes that cooperatively monitor physical or environmental conditions. One of the greatest benefits of wireless sensor networks is that they are capable of generating a more complete view of the sensed environment by acquiring larger quantities of correlated data than independent sensor monitors. The aircraft cabin is a highly dynamic environment which necessitates the use of more advanced sensing systems. It is with the motivation of painting a better picture of the aircraft cabin environment that such a wireless sensor network is being designed and prototyped. This paper discusses the design considerations required for wireless sensor networks in the aircraft cabin environment, as well as an overview of past and present systems developed for use in aircraft cabin environmental sensing. In addition to the sensor network, supporting tools are also discussed to enable analysis of the data collected. The primary goal of this research is to provide sensing tools to enable better characterization of the aircraft cabin environment.
