“…What is worth mentioning is the fact, that Energy Harvesting area is developing quite fast focusing on the optimization problems [20], new designs [21] and new ways of sources of excitations [22]. Definitely, we can state that our system is the new branch in the area of study of piezo-electric energy harvesting systems, which is developing due to the relatively high output voltage/power level by the small deflection of the piezo-patch [23].…”

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.

“…Today, piezoelectric energy harvesters can be used to power small electronic devices, such as measurement equipment, in remote or hostile environments where batteries are not a viable option, and the power consumption of these small electronic devices can be reduced by tens of mW, as shown in Table 1. Energy-harvesting systems accommodate three main sources from which electrical energy is scavenged (such as sunlight, wind, human heat, or vibration), a harvesting mechanism (to convert ambient energy to electrical), and the load (where output electrical energy is stored) [1][2][3][4][5][6]. Due to the limitations of batteries, in the future, vibrational energy-harvesting technology will be used, which converts vibration energy into electrical energy to power small electronic devices, such as measuring instruments in remote or hostile environments where batteries are not an available option, and this is the only solution [7][8][9].…”

In the current era, energy resources from the environment via piezoelectric materials are not only used for self-powered electronic devices, but also play a significant role in creating a pleasant living environment. Piezoelectric materials have the potential to produce energy from micro to milliwatts of power depending on the ambient conditions. The energy obtained from these materials is used for powering small electronic devices such as sensors, health monitoring devices, and various smart electronic gadgets like watches, personal computers, and cameras. These reviews explain the comprehensive concepts related to piezoelectric (classical and non-classical) materials, energy harvesting from the mechanical vibration of piezoelectric materials, structural modelling, and their optimization. Non-conventional smart materials, such as polyceramics, polymers, or composite piezoelectric materials, stand out due to their slender actuator and sensor profiles, offering superior performance, flexibility, and reliability at competitive costs despite their susceptibility to performance fluctuations caused by temperature variations. Accurate modeling and performance optimization, employing analytical, numerical, and experimental methodologies are imperative. This review also furthers research and development in optimizing piezoelectric energy utilization, suggesting the need for continued experimentation to select optimal materials and structures for various energy applications.

“…24 By modifying the physical parameters of the system, such as size, 25 shape, 26 connections, 27 or attachments 28 etc., more suitable dynamic or fluid-solid coupling characteristics of the structure can be meet to achieve higher output power 29 or wider bandwidth. 30 Topological methods are more common for the design and optimization of piezoelectric energy harvesting systems. 31 This method can not only be implemented in system-level, but also suitable for the design of piezoelectric elements.…”

In this paper, a series of leaf-like piezoelectric elements are proposed by using laminated structure of polypropylene (PP) and Polyvinylidene fluoride (PVDF) film to collect wind energy through vortex induced vibration. Topology optimization based on solid isotropic material with penalization method is employed in seeking optimal configurations of the elements. The PP and PVDF layer were set as optimization variables respectively to obtain topological layouts that would be equivalent to maximizes the overall strain energy as the objective function. Four simple shapes of piezoelectric elements with different topological configurations are manufactured and tested in wind tunnel to estimate the energy harvesting capabilities. The experimental results show that the reinforcement optimized long trapezoid model has the highest open-circuit output voltage of 4.01 V and output power of 6.125 μW at the wind speed of 12 m/s. For the optimization of piezoelectric materials, the short trapezoid model can reach the open circuit output voltage of 2.061 V and output power of 1.158 μW. It indicated that the topology optimization can indeed improve the energy harvesting efficiency of the piezoelectric element. However, this method is not universal at present, which means that the external shape of the model will influence the performance of the relevant optimization results.
