For managing the soaring power demand, various types of Energy Harvesting Systems (EHS) have been developed. The energy harvesting from unutilized natural renewable sources using piezoelectric transducers is one of them. Day-by-day different analytical models are being reported with different piezoelectric transducers to improve the energy efficiency and output power of the energy harvesting systems. The goal of this paper is to review the PEH (Piezo-electric Energy Harvesting) systems developed in last decade to harness energy required for small electronics. The Piezo-electric energy harvesting system works on the phenomena of direct piezo-electric effect; i.e. the transducer generates electric energy when it is exposed to mechanical stress/pressure/vibration. The suitability of piezo-electric transducer for different applications depends upon the piezo-electric materials, their shapes and configurations. In this article the different piezoelectric materials and the transducer configurations have been discussed. The performance parameters of different piezo-electric energy harvesting systems have been analyzed and the scope of improvement in the existing systems has been discussed in this manuscript.

“…Kinetic energy exists in many applications of the built environment such as engines, heavy equipment, highways, and railways [ 5 ]. Autonomous condition monitoring of rotating machinery is a possible application of PEHs [ 6 , 7 ], as well as health monitoring of aerospace structures [ 8 ]. The field of PEH evolved from the field of passive vibration damping [ 9 ], which employs mechanical systems or fluids to reduce vibration in machinery.…”

A flutter-type, nonlinear piezoelectric energy harvester was tested in various combinations of aerodynamic and harmonic base excitation to study its power output and efficiency. The commercial polyvinylidene fluoride film transducer LDT1-028K was used in 33 excitation mode. The aerodynamic excitation was created by a centrifugal fan and the base excitation by a cone speaker. The excitations were produced by varying independently the mean airflow velocity and the frequency of base vibration. A capacitive load was used to store the harvested energy. A line laser was employed along with long exposure photography and high-speed video, for the visualization of the piezo film’s mode shapes and the measurement of maximum tip deflection. The harvested power was mapped along with the maximum tip deflection of the piezo-film, and a process of optimally combining the two excitation sources for maximum power harvesting is demonstrated. The energy conversion efficiency is defined by means of electrical power output divided by the elastic strain energy rate of change during oscillations. The efficiency was mapped and correlated with resonance conditions and results from other studies. It was observed that the conversion efficiency is related to the phase difference between excitation and response and tends to decrease as the excitation frequency rises.

“…For instance, using solar energy to power remote mines and oil extraction facilities, or to provide electricity for remote sensing are two examples of the use of renewable energy in the modern era. Specifically, these are examples where renewable energy is provided for applications located far from a power distribution network, which can reduce the negative environmental effects [ 5 , 8 , 9 , 10 ].…”

An open-water wave energy converter (OWEC) made of a new soft platform has been developed by combining piezoelectric macro-fiber composites (MFCs) and a low-cost elastomer. In the past decades, numerous types of water wave energy conversion platform have been developed and investigated, from buoys to overtopping devices. These harvesters mainly use electromagnetic-based generators, and they have faced challenges such as their enormous size, high deployment and maintenance costs, and negative effects on the environment. These problems hinder their practicality and competitiveness. In this paper, a soft open-water wave energy converter is introduced which integrates piezoelectric MFCs and bubble wrap into an elastomer sheet. The performance of the OWEC was investigated in a wave flume as a floatable structure. The maximum 29.7 µW energy harvested from the small OWEC represents a promising energy conversion performance at low frequencies (<2 Hz). The elastomer was able to protect the MFCs and internal electrical connections without any degradation during the experiment. In addition, the OWEC is a foldable structure, which can reduce the deployment costs in real-world applications. The combination of no maintenance, low fabrication cost, low deployment cost, and moderate energy harvesting capability may advance the OWEC platform to its real-world applications.
