“…The SPL value obtained in this case at the position (0,0) was equal to 105.24 dB at the frequency of 4200 Hz. By installing three piezoelectric patches in the position of three defects created in case (12), it could harvest energy in ve frequencies, which compared to the single-defect case, higher power can be harvested. In this case, the maximum harvested voltage was equal to 7.98 mV, which was generated at the frequency of 3980 Hz.…”

“…Therefore, researchers have proposed different ways to increase the energy density of acoustic waves. Materials with piezoelectric properties are widely used as tools that convert mechanical (vibrational) energy into electrical energy [6][7][8][9][10]. Application of acoustic energy harvesting is used on noisy roads and streets and setting up wireless sensors [11].…”

Energy harvesting from the environment has been one of the important challenges for researchers in recent years. Acoustic energy is one of the natural sources of mechanical energy that can be converted into electrical energy by using metamaterial or piezoelectric. In such a way that by creating a defect in a regular lattice of the crystal, at the point of defect, the concentration of sound pressure was created, and by installing the PVDF piezoelectric patch, mechanical energy can be converted into electrical energy. In this research, to identify a suitable model to harvest maximum acoustic energy, the effect of various lattices including circular, rhombus, rectangular, square-rhombic, square-rectangular, and rhombus-rectangular lattices on the sound pressure level (SPL) and energy harvesting was investigated. Also, the effect of changing the position of the defect and increasing the number of defects on the SPL was studied. The simulated results were calculated using Comsol Multiphysics 6.0. The validation of the results was confirmed by comparing them with the results of previous studies. The results showed that a square-rhombic lattice can provide the highest SPL and consequently the highest harvested energy. In the square-rhombic lattice, by using the optimal resistance of 15 kΩ at the frequency of 4220.4 Hz, the voltage and power were 11.34 mV and 4.15 nW, respectively.

“…This sound deadening effect of the PnC is well known for noise reduction applications. [20][21][22][23][24][25] In contrast to this expectable behavior, the defect PnC displays a sound pressure that increases significantly within the bandgap. The averaged sound pressure of the defect PnC is 18 dB higher than the full PnC and 2 dB higher than the bare plate.…”

“…In addition to single wave applications, the use of bandgaps has been extended to interaction problems between elastic and acoustic waves, i.e., vibro-acoustics. [20][21][22][23][24][25][26][27] The main focus of the vibro-acoustic applications of bandgap structures is the reduction of noise radiating from vibrating structures due to attenuation of vibrational energy. Liu et al 20 proposed a locally resonant sonic material that has a bandgap in the low frequency regime and blocks the sound transmission surpassing the mass density law.…”

In the wake of the rapid development of the Internet of Things (IoT) and artificial intelligence (AI) technology, a huge amount of wireless sensing nodes (WSNs) is urgently in demand in all aspects of daily production and living, such as smart cities, smart transportation, and intelligent monitoring. However, it has become one of the crucial challenges in the development of IoT technology to fulfill the requirements of energy consumption for enormous amounts of WSNs. Therefore, it not only possesses great potential to realize in situ power supply of WSNs by harvesting environmental energy but also can address the problems of durability, maintenance, and cost that exist in battery power supply. In particular, acoustic energy is ubiquitous in the environment but not efficiently utilized. Meanwhile, piezoelectric nanogenerators (PENG) and triboelectric nanogenerators (TENG) are capable of accomplishing efficient conversion of broadband, high entropy, and weak energy as the new energy conversion technology. Therefore, the basic principle of acoustic energy harvester based on nanogenerators (NGs) is firstly discussed. Then, the advances of acoustic energy harvesters based on NGs in the viewpoint of acoustic energy resonator structures are systematically reviewed for the first time. This review not only covers the working mechanism, structural design, and application scenarios of acoustic energy harvesters but also explores the advances in ultrasonic energy harvesting based on NGs. Finally, existing challenges and prospects for future development are systematically discussed, which will facilitate the development of acoustic energy harvesting based on NGs.
