“…The open-circuit voltage could be improved through reducing the size of damping orifice, where the output voltage reached the maximum value of 51.6 V at the air pressure of 0.5 MPa with the valve opening of 1/6. Li et al (2020) proposed a piezoelectric energy harvester based on a spring-mass-spring oscillator, of which the piezoelectrics operate in the d33 mode. By using lead zirconate titanate (PZT-4) ceramics as model materials, they systematically characterized the performance of the energy harvester.…”

We have designed a piezoelectric power nano-generator unitcell (device) where gas molecules are moving in Brownian motion and these molecules collide with a piezoelectric material. Due to the collision by gas molecules on the piezoelectric material, a voltage difference is induced across the piezoelectric material. We developed a simple model to calculate the voltage and power generation by using the method of statistical mechanics. Here we considered that gas molecules are not interacting with each other. We have created a design to connect nano-generator unitcells to form a chip in series configurations to enhance the production of the power nano-generation. Our design for the new power generator shows that as the thickness of the piezoelectric material increases so does the voltage generation. Our design can continuously generate electricity and this feature is better than solar panels that only work during daytime and windmills that cannot work without wind. It can work in a natural atmosphere environment. In the future when a new way of printing chips at low costs is discovered, then generating electricity will be very cheap using our design.

“…In recent years, the structural vibration characteristics under friction, including the transformation between dynamic and static frictions [17], system stability analysis [18,19], and energy harvesting under friction [20,21] have received attention from researchers. Studies have been conducted on vibration response [22][23][24] and energy harvesting from friction [25][26][27][28][29][30]. Li et al solved the final wear shape of elastic indenter by the dimension reduction method.…”

“…Li et al proposed a piezoelectric energy harvester based on spring mass oscillator. The results showed that the harvester can output high voltage at resonant frequency [ 28 ]. Chen et al sandwiched the piezoelectric plate between two layers of elastic damping elements and proposed a method to realize energy harvesting through frictional vibration and vibration reduction at the same time [ 29 ].…”

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.

“…Vibration energy harvesters (VEHs), which can harvest energy from ambient vibrations and convert it into electrical energy automatically, have become a promising alternative for a range of applications. There are three main approaches to harvesting energy from vibrations, which involve the use of either electrostatic [1][2][3][4][5][6], electromagnetic [7,8] or piezoelectric [9][10][11][12][13][14][15][16][17][18][19] principles. As a general rule, the main challenge in vibrational energy harvesting is that the maximum system performance is achieved when the resonant frequency of the VEH matches the external vibration source.…”
