“…Some recently conducted reviews mentioned the potential of recovering a few hundred watts for a passenger car driven in experimental tests as well as some mathematical models [4,5]. One of the ways to convert the mechanical energy from the vehicle suspension to electric energy is through piezoelectric materials [6]. Therefore, the objective of this chapter is to present the coupling between a piezoelectric element and a dynamic system in the context of predicting the recovered electric power and energy density for piezoelectric materials, especially the PZT (Lead Zirconate Titanate).…”

Piezoelectric vibration energy harvesting has been investigated for different applications due to the amount of wasted vibration from dynamic systems. In the case of piezoelectric materials, this energy lost to the environment can be recovered through the vibration of energy harvesting devices, which convert mechanical vibration into useful electrical energy. In this context, this chapter aims to present the mechanical/electrical coupling on a simple dynamic system model in which a linear piezoelectric material model is incorporated. For this purpose, a mechanical/electrical element of a piezoelectric disk is developed and integrated into a lumped mass, viscous damping, and spring assembling, similar to a quarter car suspension system. Equations of motion for this dynamic system in the time domain can be solved using the finite element method. The recovered electric power and energy density for PZT (Lead Zirconate Titanate) from the wasted vibration can be predicted considering that the road roughness is introduced as an input mode.

“…Darabseh et al [30] designed a piezoelectric stacked suspension spring device. The experiments showed that the peak voltage and power of 19.11 V and 36.74 mW, respectively, could be generated in a quarter car model under resonant excitation with the frequency of 1.46 Hz and the acceleration amplitude of 0.5 g. Yuri and José [31] established a 19 DOF piezoelectric model for the full vehicle and compared five piezoelectric materials for energy capturing, and concluded that PZT-5 H (Pbbased Lanthanumdoped Zirconate Titanates) was the most effective, and the feedback energy RMS value could reach 20 mW. Li et al [32] investigated the energy dissipation of a piezoelectric stack-based suspension system for marine vehicles and experimentally verified that six piezoelectric stack units produced a maximum combined peak power greater than 0.57 W which could realize at least 200 parallel connected led power supply.…”

With the rapid development of the semiconductor field, the application of micro-electro-mechanical systems embedded in smart devices and driverless vehicles is gradually widespread, and the problem of the self-powered of devices has gradually been attention. Hence, this study propose a novel hydro-pneumatic suspension system by embedding piezoelectric energy harvester into hydro-pneumatic suspensions, which makes the suspension structure simple and achieves the effect of self-powered for the monitoring and the diagnostics of a vehicle or its subsystems. The mathematical model of intermediate fixed piezoelectric energy harvester with hydro-pneumatic suspension was established. The influence of hydraulic component and exitation parameters of suspension system on damping force and power is analyzed. Numerical simulation proves that the novel hydro-pneumatic suspension with piezoelectric energy harvester is justified to achieve self-powered. The bench test proves the accuracy of some of the conclusions of the simulation and the feasibility of the structure.

“…Piezoelectric transducers perform well in terms of power density compared to their counterparts which suffer from low energy density [37]. Thus, the piezoelectric transducers been used by many researchers to convert vehicle vibration to electricity, owing to their ease of implementation and ability to produce high voltage at a low cost [3,38,39]. Lee et al [40] developed a piezoelectric energy-harvesting shock absorber, which harnesses electrical energy from changes in fluid pressure caused by piston motion.…”

Recent research has examined the possibility of recovering energy from mechanical vibration induced by a vehicle shock absorber using piezoelectric and electromagnetic transducers. In terms of automotive applications, piezoelectric vibration energy harvesting shows promise for recapturing some (even if small) amounts of vehicle vibration energy, which would otherwise be wasted through the vehicle dampers. Functional materials, such as piezoelectric materials, are capable of converting mechanical energy into useful electrical energy and vice versa. In this paper, an innovative rotational piezoelectric vibration-energy-harvesting device is presented that employs a magnetic coupling mechanism and provides robust performance over a range of frequencies. The piezoelectric energy harvester is driven by a unidirectional suspension system. An experimental investigation was carried out to study the performance of the manufactured prototype. We observed no damage to the prototype after operating continuously at a vibration amplitude of 5 mm at a frequency of 2.5 Hz for over 10,000 cycles. In addition, the presented regenerative suspension system is capable of producing high and relatively steady open-circuit voltages, irrespective of excitation frequencies. The results demonstrate that regenerative shock absorber is robust and has a broad frequency range.
