“…Vibrations can be converted into energy by numerous techniques: electromagnetic, electrostatic/capacitive, and piezoelectric [15]. Moreover, the piezoelectric devices are appropriate to be optimized for a certain excitation frequencies and that can facilitate the raise of the system efficiency, see Kurt et al [22] and Uzun et al [18]. According to Cottone [6], non-linear oscillators can offer the option of broadening the response of vibration energy systems, in that way they can physically respond to changes in driving frequency, Uzun et al [23].…”

“…Among the aforementioned techniques, piezoelectrics have some advantages such as elevated power density and voltage. In addition, the piezoelectrics are appropriate to be optimized for some excitation frequencies and can be useful to increase the system efficiency, see Kurt et al [22] and Uzun et al [18]. The materials used for piezoelectric conversion are naturally-occurring ones as crystals, ceramics, and polymers, see Patel et al [28] and Westwood [29].…”

Abstract:Over the past few years, it has been established that vibration energy harvesters with intentionally designed components can be used for frequency bandwidth enhancement under excitation for sufficiently high vibration amplitudes. Pipelines are often necessary means of transporting important resources such as water, gas, and oil. A self-powered wireless sensor network could be a sustainable alternative for in-pipe monitoring applications. A new control algorithm has been developed and implemented into an underwater energy harvester. Firstly, a computational study of a piezoelectric energy harvester for underwater applications has been studied for using the kinetic energy of water flow at four different Reynolds numbers Re = 3000, 6000, 9000, and 12,000. The device consists of a piezoelectric beam assembled to an oscillating cylinder inside the water of pipes from 2 to 5 inches in diameter. Therefore, unsteady simulations have been performed to study the dynamic forces under different water speeds. Secondly, a new control law strategy based on the computational results has been developed to extract as much energy as possible from the energy harvester. The results show that the harvester can efficiently extract the power from the kinetic energy of the fluid. The maximum power output is 996.25 µW and corresponds to the case with Re = 12,000.

“…Among piezoelectric harvesters, a cantilever-type bending structure has been most frequently investigated. [9][10][11][12][13][14] The performance of a piezoelectric energy harvester has often been reported in terms of power density (output power per harvester volume, unit: W cm À3 ) measured at a given frequency and acceleration of vibration. The reported power density values for piezoelectric energy harvesters range from lW cm À3 to a few mW cm…”

A wideband vibration energy harvester based on a folded asymmetric gapped cantilever Appl. Phys. Lett. 104, 053902 (2014) This study provides comprehensive analysis of the structure-performance relationships in cantilever-type piezoelectric energy harvesters. It provides full understanding of the effect of all the practical global control variables on the harvester performance. The control variables considered for the analysis were material parameters, areal and volumetric dimensions, and configuration of the inactive and active layers. Experimentally, the output power density of the harvester was maximum when the shape of the beam was close to a square for a constant bending stiffness and a fixed beam area. Through analytical modeling of the effective stiffness for the piezoelectric bimorph, the conditions for enhancing the bending stiffness within the same beam volume as that of a conventional bimorph were identified. The harvester configuration with beam aspect ratio of 0.86 utilizing distributed inactive layers exhibited an giant output power of 52.5 mW and power density of 28.5 mW cm À3 at 30 Hz under 6.9 m s À2 excitation. The analysis further indicates that the trend in the output power with varying damping ratio is dissimilar to that of the efficiency. In order to realize best performance, the harvester should be designed with respect to maximizing the magnitude of output power. V C 2014 AIP Publishing LLC.
