“…Apart from the tuning of the material composition, the rest of the piezoelectric energy harvesting research has focused on the structural design and optimization for different applications. The most popular structures used in piezoelectric energy harvesters include cantilever, stack cymbal configuration, diaphragm configuration, and shear mode configuration . The cantilever structure is suitable for low input force, small acceleration, and mid‐high frequencies (tens of Hz or above), but it allows large amplitude/deformation.…”

Energy harvesting technology may be considered an ultimate solution to replace batteries and provide a long-term power supply for wireless sensor networks. Looking back into its research history, individual energy harvesters for the conversion of single energy sources into electricity are developed first, followed by hybrid counterparts designed for use with multiple energy sources. Very recently, the concept of a truly multisource energy harvester built from only a single piece of material as the energy conversion component is proposed. This review, from the aspect of materials and device configurations, explains in detail a wide scope to give an overview of energy harvesting research. It covers single-source devices including solar, thermal, kinetic and other types of energy harvesters, hybrid energy harvesting configurations for both single and multiple energy sources and single material, and multisource energy harvesters. It also includes the energy conversion principles of photovoltaic, electromagnetic, piezoelectric, triboelectric, electrostatic, electrostrictive, thermoelectric, pyroelectric, magnetostrictive, and dielectric devices. This is one of the most comprehensive reviews conducted to date, focusing on the entire energy harvesting research scene and providing a guide to seeking deeper and more specific research references and resources from every corner of the scientific community.

“…Among the various techniques for energy conversion, most of the current investigations on transforming ambient vibrations into electrical power have been focused on piezoelectric energy harvesters (PEHs) [6,11,12]. The main shortcoming of piezoelectric-based harvesting of electrical energy from vibrations is low efficiency [4,13]. That is, current MEMS PEHs can harvest only a small percent of the available energy.…”

“…New designs of PEHs have to be developed to overcome this issue. Many types of research have been focused on the configuration of the unimorph cantilever beams [13]. This is due to their larger conversion efficiency and simplicity in terms of system configuration [14].…”

“…Arrays of multi-cantilever structures have been studied in [17,18] by which the resonance frequency has been adjusted to the ambient environment, the response of the energy harvester has been expanded and the number of resonances within a certain frequency band has been maximised. A tunable trapezoidal and a rectangular piezoelectric bimorph energy harvester have been proposed in [13]. One of the most challenging issues in the development of MEMS devices is the application of an appropriate automated design and optimisation process to eliminate the expense of the trial and error approaches.…”

“…Mineto et al [49] identified the highest output power of 6500µW was obtained when PZT covered approximately half of the substrate. Meanwhile, many studies [50][51][52][53][54][55] discussed the possibility to improve output power by modifying the geometry of the conventional rectangular beam to a trapezoidal and triangular shape. Benasciutti et al [56] found that the output power was dependent on piezoelectric's surface area, particularly the width.…”

In the past decade, there has been rapid development in piezoelectric energy harvester due to its limited application and low output power. This paper critically reviews the strategies implemented to improve the power density for low-frequency applications. These strategies include piezoelectric material selection as well as optimisations of shape, size and structure. The review also focuses on the recent advances in multi-modal, nonlinear and multi-directional energy harvesting. Based on the comprehensive summary of the normalised power density at 1g acceleration, it was found that most works fell in the second quadrant of low frequency and high power density. The maximum value was around 1mW/mm3 /g. Adding an extension of beam or spring to the conventional piezoelectric beam could enhance the normalised power density dramatically. Additionally, the multi-modal energy harvester exhibits broader bandwidth when its multiple resonance peaks get closer. The findings indicate that the anticipated performance of a piezoelectric harvester can be attained by achieving the trade-off between output power and bandwidth. To achieve high performance at low frequency, the following factors are essential: excellent material characteristics optimised geometry for high strain energy density, excellent flexibility, high excitation amplitude and broad bandwidth.
