Miniaturized power modules for aircraft bodies
Aircraft maintenance can be time consuming and expensive. It is much simpler if the airplane itself reports, where maintenance is required. The best solution is an approach for the sensor network, which even provides its own power supply and is therefore independent of electrical wiring and this is what has now been developed by EADS EADS Deutschland GmbH (Germany), in cooperation with the Institute of Sensor and Actuator Systems at Vienna University of Technology (TU Vienna). For each individual sensor, electricity is produced by a thermoelectric generator with a small water tank, storing thermal energy. The electricity is simply generated from the temperature difference between the icy cold air in high altitudes and the water based heat storing unit (and vice versa). This novel approach for providing locally the energy for the operation of the sensor network could not only facilitate aircraft maintenance, but also increase comfort for travelers.
