“…Observing the potential of the system, it can be applied in the external environment. For instance, it can be applied as the coupling with rotating blade [25], in structural health monitoring (SHM) in buildings [26] or used by the side of highways, where the wake-induced vibration phenomena is observed by cars [27]. One of potential ways it can be the coupling of the system with unmanned aerial vehicles (UAVs) for powering the low-demanding sensors [28,29].…”

This paper analyzes a piezoelectric system made of a smart lead zirconate material. The system is composed of a monolithic PZT (piezoelectric ceramic) plate made of a ceramic-based piezoelectric material. The experiment was conducted on a test stand with a GUNT HM170 wind tunnel and a special measurement system. The developed bluff-body shape mounted on an elastic beam with a piezoelectric was mounted on a mast with arms. Springs were fixed on the arms to limit the movement of the test object. Air flow velocity in the wind tunnel and forced vibration frequencies were changed during the tests. The recorded parameters were an output voltage signal from the piezoelectric element and linear accelerations at selected points of the test object. The highest energy efficiency of the tested system was specified from mechanical vibrations and air flow. The results of the tests are a resonance curve for the tested system and a correlation of RMS voltage and acceleration as a function of the velocity of air flow for the excitation frequency f ranging from 1 to 6 Hz. The tests specified the area where the highest output voltage under the given excitation conditions is generated.

Inspired by the shield scale on the shark surface, a D-type bionic fin with non-smooth surface is proposed and used in tandem cylinders piezoelectric energy harvesters (PEHs) for the utilization of wind energy on the roof of buildings. The repeating unit of D-type bionic fin is semicircle, and the corresponding center angle of each repeating unit is 7.2°. PEHs consist of a piezoelectric cantilever beam and a wind-interference cylinder connected to the beam tip. The influence of the spacing ratio on the amplitude of PEHs with D-type bionic fins added under elastic interference is studied through wind tunnel tests and three installation positions are designed: only installed upstream, only installed downstream, and not installed upstream and downstream (bare). It is found that the maximum amplitude response law of the upstream piezoelectric energy harvester (UPEH) is not affected by the D-type bionic fins, and the D-type bionic fins can make the downstream piezoelectric energy harvester (DPEH) realize the change of the maximum amplitude from small spacing ratio to large spacing ratio. In addition, the influence of the installation position of D-type bionic fins on the output voltage of upstream and downstream PEHs is also studied. The research shows that the addition of D-type bionic fins significantly changes the vibration behavior of PEHs. D-type bionic fins can enhance the energy harvest performance by coupling "coupled vortex-induced vibration" and wake induced galloping (WIG), and increasing the surface velocity of PEHs. D-type bionic fins can also expand the bandwidth of the voltage harvested by the PEHs. The analysis of the power under the experimental wind speed shows that the installation of D-type fins in PEHs can increase the output power of the upstream and downstream PEH by 392.28% and 13% respectively compared with the bare piezoelectric energy piezoelectric energy harvester (BARE-PEH). In addition, the computational fluid dynamics is used to analyze the flow pattern, wake structure and lift coefficient of PEHs, and the reason why the installation of D-type bionic fins in the upstream has an impact on the harvest performance of upstream and downstream PEHs at 1.5 spacing ratio is explained.

This study parametrically investigates the efficiency of an integrated energy harvesting system that consists of a piezoelectric patch attached to a cantilever beam and V‐shape bluff bodies with various apical angles. V‐shape bluff bodies are connected to a cantilever beam with a revolute joint that represents a two degrees‐of‐freedom configuration. The mechanical energy of the galloping and fluttering motions, resulted from the vortex shedding appears downstream of the bluff bodies, is converted into electricity by means of a piezoelectric patch. The apical angle of the V‐shape geometries, varies between 0° and 180°, is the main parameter where the generated voltages and the related power curves are the major results for the evaluation of the efficiency of this harvesting system. Based on the experimental examinations, the maximum output power of 0.295 mW is produced at a wind speed of 10 m/s for the apical angle of 180° and the electrical resistance of 230 kΩ. Moreover, the proposed energy harvester system can still produce usable output power for the apical angles ranges from 0° to 20° and from 170° to 180°.This article is protected by copyright.
