A State-Of-The-Art Review of Car Suspension-Based Piezoelectric Energy Harvesting Systems

Abstract

One of the most important techniques for energy harvesting is the clean energy collection from the ambient vibration. Piezoelectric energy harvesting systems became a hot topic in the literature and attracted most researchers. The reason behind this attraction is that piezoelectric materials are a simple structure and provide a higher power density among other mechanisms (electromagnetic and electrostatic). The aim of this manuscript is to succinctly review and present the state of the art of different existing vibrational applications utilizing piezoelectric energy harvesting technique. Meanwhile, the main concentration is harvesting energy from a vehicle suspension system. There is a significant amount of dissipated energy from the suspension dampers that is worthy of being harvested. Different mathematical car models with their experimental setup are presented, discussed, and compared. The piezoelectric material can be mounted in different locations such as suspension springs, dampers, and tires. The technique of implementing the harvester and the amount of power harvested from each location are analyzed. The evaluation of the electrical harvesting circuits and different storage devices for the harvested power are also discussed. The paper will also shed light on the variety of potential applications of the harvested energy.

Piezoelectric method‐based harvested energy evaluation from car suspension system: Simulation and experimental study

“…From the simulation parameters utilized in the analysis, the harvested power from two piezoelectric stacks installed in series with the front and rear suspension springs was calculated. However, there are many ways to increase the harvested power as discussed by Al‐Yafeai et al 54 Car suspension parameters, piezoelectric stack parameters, sensor location, and the road roughness are highly affecting the amount of the harvested power.…”

Progress in the Applications of Smart Piezoelectric Materials for Medical Devices

“…Consequently, different layers for sensors made from textiles [ 89 , 90 , 91 , 92 ], hydrogels and soft polymers [ 93 , 94 , 95 ], elastomers [ 96 , 97 , 98 ], nanofiber layers [ 99 , 100 , 101 ], or thin polymer layers [ 102 , 103 , 104 ] are used. Additional piezoelectric, piezoresistive, triboelectric, thermoelectric properties of these piezoelectric materials make them good candidates for smart sensing applications [ 105 , 106 , 107 ].…”

Energy harvesting from car suspension system: Mathematical approach for half car model

“…Moreover, the vehicle suspension system and piezoelectric stack parameters have shown an essential impact on the amount of harvested energy. However, there are several solutions proposed by Al-Yafeai et al [49] in order to maximize the harvested power from vehicles. Improved the material properties of the piezoelectric material to be equipped with the car will help in harvesting most of the vibrations subjected to the cars.…”
