“…Conversion of the vibration energy to electricity is mainly achievable through three popular methods namely electromagnetic [14][15][16] , triboelectric [17][18][19] and piezoelectric [20][21][22][23] . Piezoelectric elements have been widely utilized in vibration energy harvesting so far [24][25][26] , however, the low power and low efficiency of the PZT based energy harvesters is still a main challenge. Enhancement of these limitations is mainly attained through material science by changing the composition of piezoelectric elements 27,28 or by structural solutions 29,30 consist of metamaterials.…”

Piezoelectric (PZT) components are one of the most popular elements in vibration sensing and also energy harvesting. They are very well established, cost effective and available in different geometries however there are still several challenges in their application particularly in vibration energy harvesting. They are normally narrow-band elements and work in high-frequency range. Their efficiency and power extraction density are also generally low compared with different electromagnetic techniques. Auxetic structures are proposed here to enhance efficiency of the piezoelectric circular patches in vibration energy harvesting. These kinds of patches namely PZT buzzers are inexpensive (less than 10 USD) elements and easily available. Two novel circular auxetic substrates are proposed to improve power extraction capacity of the conventional piezoelectric buzzers. Negative Poison’s ratio of the proposed meta-structure helps in efficiency enhancement. The concept is introduced, analyzed and verified through the finite element modeling and experimental testing. The idea is proved to work by comparing the harvested electrical power in the auxetic design against the conventional plain system. A parametric study is then carried out and effects of important electrical and geometrical parameters as well as the material property on the power extraction efficiency are assessed to arrive at optimum parameters. It is shown that by employing the auxetic design, a remarkable improvement in the harvested power is achievable. It is shown that for the two proposed auxetic designs, at the resonance frequency, we could reach to 10.2 and 13.3 magnification factor with respect to the plain energy harvester. Another important feature is that the resonant frequency in these new designs is very much lower than the conventional resonators. Results of this study can open a new path to application of inexpensive PZT buzzers in large-scale vibration energy harvesting.

“…However, the fuel efficiency is below 75% due to various losses in which a significant amount of energy loss is irreversible such as thermal losses and friction losses, and only 22.5% of the energy is used to power the wheel [1]. Many types of research aim to reduce the fuel consumption by recovering waste energy from different parts of the vehicle, such as engine [2], tires [3][4][5], suspension [6][7][8][9][10][11][12][13], and braking [14][15][16][17][18][19][20].…”

A novel piezoelectric energy generator embedded in vehicle brake pads and excited by magnetic repulsion is developed. The generators are mounted on the backing plate of the brake pad through the perforated friction layer. Slotted brake rotor with embedded magnets is equipped to ensure the braking performance of the vehicle. During the braking process, dynamic magnetic repulsion will be generated when the overlapping area of the embedded magnets in the brake pad and brake rotor is changing. The magnetic repulsion is generated when two magnets are close to each other, and the force is proportionally changing with the overlapping area of the two magnets. As a result of repulsion between the magnets, the piezoelectric stack will experience compressive forces, creating an electrical charge for generating energy. To illustrate the voltage generation, a mathematical model with experimental verification is established to calculate the electric charge and output voltage considering the charge dissipation. The energy harvesting process is evaluated by simulating the transient charging of the storage capacitor through the diode bridge, which was experimentally validated in literature. The influences of the dimensional and material properties of the piezoelectric stack, the vehicle speed, the magnetic repulsion, the diameter of the magnetic actuator, the capacitance of the storage capacitor and the distance between rotor center to the actuator on the root mean square (RMS) of the charging power are discussed. A total RMS power of 0.0710 W can be achieved with thirty-six generators embedded in both the inner and the outer brake pads within one brake caliper using APC850 (PZT4) material, and a total RMS power of 1.1226 W can be achieved using PMN-PT-B (PT=0.3-0.33) material at 120 km/h speed of the vehicle. This novel generator will be useful for efficient and practical energy harvesting applications during vehicle braking process.

A new electrical power generation device based on high-frequency dynamic piezoelectric shear deformation under friction is developed. During the operation of a moving plate compressed and sliding on the top of a piezoelectric patch with constant velocity, dynamic shear deformation of the elastic piezoelectric patch is excited by periodic friction force and status (sliding and stick) variation. The dynamic piezoelectric shear strain can then generate continuous electrical power for energy absorbing and harvesting applications. The design of the piezoelectric couple device is first provided, and its mechanism, dynamic response and electric power generation under friction are described by a detailed iteration model. By comparing with previous experimental results, the accuracy of the proposed model is proven. Through numerical studies, the influences of the equivalent mass of the system, the velocity of the sliding object, the static friction coefficient and its lower limit, as well as the friction force delay rate on the power generation are obtained and discussed. The numerical results show that with the proposed design, up to 50-Watt maximum electrical power could be generated by a piezoelectric patch with a dimension of $$20\times 2\times 6$$ 20 × 2 × 6 cm under continuous friction with the moving plate at the velocity of 15 m/s. The possible bi-linear elastic stiffness variation of the system is also introduced, and the threshold of bi-linear elastic deformation, where the system stiffness changes, can be optimized for obtaining the highest power generation.
