“…The piezoelectric cantilever array is a typical multi-DOF system, and different resonant frequencies can be obtained by adjusting the size of the cantilever beam and the tip masses. Dai et al [ 33 ] proposed a multi-DOF wideband PEH consisting of five tip masses, two U-shaped cantilever beams, and a straight beam with five resonant frequencies [ 34 ], which can effectively enlarge the operating bandwidth and collect vibration energy in low frequencies [ 35 , 36 , 37 ]. Ding et al [ 38 ] proposed a variant power generator array using an arc-shaped piezoelectric cantilever beam array, which had a satisfactory output performance.…”

This work presents a novel bird-shaped broadband piezoelectric energy harvester based on a two-DOF crossed beam for low-frequency environmental vibrations. The harvester features a cantilever mounted on a double-hinged beam, whose rotating motions effectively diminish its natural frequencies. Numerical simulation based on the finite element method is conducted to analyze the modal shapes and the harmonic response of the proposed harvester. Prototypes are fabricated and experiments are carried out by a testing system, whose results indicate a good agreement with the simulation. The multi-frequency energy harvesting is achieved at the first-, second-, and fifth-order resonances. In particular, the proposed harvester demonstrates the remarkable output characteristics of 9.53 mW and 1.83 mW at frequencies as low as 19.23 HZ and 45.38 Hz, which are superior to the majority of existing energy harvesters. Besides, the influences of key parameters on the harvesting performance are experimentally investigated to optimize the environmental adaptability of the harvester. This work provides a new perspective for efficiently harvesting the low-frequency vibration energy, which can be utilized for supplying power to electronic devices.

“…However, the disadvantages of traditional chemical batteries, such as large volume, short service life, regular replacement and environmental pollution, limit their application and development prospects. Vibration in the surrounding environment [6], human motion [7] and rotary kinetic energy [8][9][10] are collected for this type of micro-power devices, which is expected to replace traditional chemical batteries into new micro-power supplies. Rotational energy has the advantages of stability and durability, easy integration, environmental protection and no pollution, and is widely distributed in the environment.…”

In this paper, In order to make use of the rotating motion characteristics of the roller cage shoe structure in vertical shaft lifting guide device, a nonlinear gyromagnetic excitation piezoelectric superposition beam energy harvester with compact structure, non-contact and high energy harvester efficiency is designed. The nonlinear force between moving magnet and stationary magnet is used to transform the rotating motion of the roller cage shoe into the end vibration of the piezoelectric vibrator. In order to improve the utilization rate of the piezoelectric plate and the low-amplitude response sensitivity of the energy harvester, acrylic material is introduced to re-place the traditional metal substrate, the bottom piezoelectric vibrator is hinged with the end of the top piezoelectric vibrator, and the middle part of the piezoelectric vibrator ends are longitudinal-superimposed beam structure with chute connection. The structural parameters, gyromagnetic excitation properties and strength of the piezoelectric vibrator are optimized and analyzed through finite element simulation and experiments, and the longitudinal and transverse arrays of piezoelectric vibrators are designed. The effects of terminal connection mode, array spacing, array number and load resistance on the power generation performance of the energy harvester are investigated. The results show that when the number of vertical arrays is 8 layers and the array spacing is 1.5 mm, higher voltage output and vibration consistency are achieved. When the horizontal array is 7 groups and the load is 10 kΩ, the maximum output power of the energy harvester is 11.26 mW, which can realize the self-power supply to the wireless transmitting node.

“…Energy harvesting from a rotating element can be realized by using a single piezoelectric element [1][2][3][4][5][6][7][8][9][10][11][12] or bigger numbers, e.g., two [14], three [15], four [16], six [17], eight [18], nine [19], or twelve [20]. If one piezoelectric element is used, it is connected directly to one full bridge rectifier, which is a main element of the electric part of harvester.…”

“…Kurt et al [26] and Bouzelata et al [27] proposed connecting three piezoelectric beams, each of which generates a different voltage waveform, to one three-phase rectifier circuit using a star connection. Micek et al [15] compared electric responses (voltage and power) in the process of energy harvesting with a three-phase rectifier, for both star and delta connections, with electric responses in the process of energy harvesting which uses parallel and serial connections of three circuits consisting of an MFC patch and a full bridge rectifier. They found that delta energy generation led to the greatest electrical power generation compared to any other connection.…”

Energy collection in a capacitor, which was charged by four connection structures of Macro Fiber Composite (MFC) patches, was the subject of laboratory research. The first structure was the delta circuit created by three MFC patches and connected with a three-phase rectifier; the second structure was the delta circuit created by three MFC patches and connected with a three-phase rectifier; the third structure was the parallel connection of three circuits, each of which consisted of an MFC patch and a full bridge rectifier; and the fourth structure the series connection of three circuits, each of which consisted of an MFC patch and a full bridge rectifier. Laboratory experiments were carried out on a laboratory stand which consisted of a rotating shaft, three MFC patches powering an energy storage system, and a data acquisition system. The star connection generated the highest values of voltage across a capacitor in the long time period. The delta connection produced the highest capacitor-charging power. The shortest time to reach a target voltage on the capacitor equal to a few volts was achieved by use of the delta or parallel connection. The delta connection generated target voltage equal to a few volts across a capacitor in the shortest time at a lower level of stress in the shaft, but the difference between the charging times by the delta circuit and by the parallel connection decreased as the stress in the shaft increased.
