“…The first and most intuitive EH modality in this case is a rotary micro-turbine which converts mechanical rotation, via electromagnetic induction, into usable electrical energy [92]. The second EH modality utilizes airflow-induced fluttering and converts the resulting mechanical into electrical energy by using, in most cases, piezoelectric devices, although electromagnetic and electrostatic transducers can be employed in this frame as well [41,92,194,195]. The second EH principle that will be considered here are acoustic EH systems based on particular design arrangements on aircraft (cavities and similar), inducing sound wave effects [196,197].…”

“…A promising but quite complex design configuration, involving additional magnets, is that of a Y-shaped bistable EH device with piezoelectric patches aimed at low-speed (3 to 7 m/s) airflows that was experimentally shown to generate noteworthy voltage outputs [202]. The design and characterization of a novel airflow EH device, based on jet-edge flow oscillations (Figure 33), proposed in [194], allows, in turn, attaining, via the oscillations of a polymeric (PVDF) piezoelectric structure (cf. above Section 2.3.2), in absolute terms only several tens of µW of maximal output power.…”

“…With a constant airflow of 200 l/min, such a system provided on a 7 MΩ resistor a maximal power output of 13 mW [203].

With the aim of increasing the efficiency of maintenance and fuel usage in airplanes, structural health monitoring (SHM) of critical composite structures is increasingly expected and required. The optimized usage of this concept is subject of intensive work in the framework of the EU COST Action CA18203 “Optimising Design for Inspection” (ODIN). In this context, a thorough review of a broad range of energy harvesting (EH) technologies to be potentially used as power sources for the acoustic emission and guided wave propagation sensors of the considered SHM systems, as well as for the respective data elaboration and wireless communication modules, is provided in this work. EH devices based on the usage of kinetic energy, thermal gradients, solar radiation, airflow, and other viable energy sources, proposed so far in the literature, are thus described with a critical review of the respective specific power levels, of their potential placement on airplanes, as well as the consequently necessary power management architectures. The guidelines provided for the selection of the most appropriate EH and power management technologies create the preconditions to develop a new class of autonomous sensor nodes for the in-process, non-destructive SHM of airplane components.
