A novel design of a hybrid piezoelectric-electromagnetic harvester for vortex-induced vibration applications inside a pipe-flow is proposed. The piezoelectric energy harvester is modeled with a macro-fiber composite with an electromagnetic oscillator. Analytical and numerical models were developed for the fluid-structure interaction. An optimization study was conducted using finite element modelling across different bluff body shapes and orientations where triangle and 2.5x ellipse were optimal choices for maximizing energy harvesting properties. An investigation into dual-mass energy harvesting was also performed for bandwidth enhancement. A secondary beam has improved the piezoelectric performance by 21% to 52%. Finally, an experimental study was conducted to verify the narrowband resonance models and validate the use of a magnetically coupled dual broadband harvester (58% enhancement). Optimization and design of the harvester has led to improvements in performance that can realize powering sensors and devices in wireless applications.

“…The work demonstrated that maximum power output and efficiency from a hybrid PE system was greater than traditional piezoelectric or electromagnetic energy harvesters and more power can be harvested from the electromagnetic than the piezoelectric system. Hafizh et al (2021) investigated the bluff body optimization parameters for resonant vibration under fluid flow for a hybrid piezoelectric-electromagnetic system. The proposed hybrid harvester departs from previous work by utilizing a vertical harvester with an internal electromagnetic compact geometry that is fully submerged in water under the influence of VIV.…”

This article proposes a novel hybrid piezoelectric–electromagnetic vortex-induced vibration energy harvester from flow of water inside of a pipe. The piezoelectric energy harvester was modeled with a macro-fiber composite P2-type while the electromechanical transduction was modeled by an elastic magnet coupled to the bluff body movement. A dual-mass configuration was proposed to increase the energy harvesting efficiency. Theoretical models and the submerged natural frequencies of the hybrid energy harvesters were outlined. Computational fluid dynamics and finite element analysis with ANSYS were used to visualize the response in synchronization and output the voltage extracted from the harvesting mechanisms. The addition of a secondary system improves the amount of harvestable energy and outputs more energy than just a single system. This demonstrates the superiority of a dual-mass hybrid system. A tuned secondary beam was used for L-body configurations to make use of inline oscillations, and the secondary piezoelectric output improved for all configurations. Secondary beam tuning also improved the performance of the harvester by any amount between 21% and 52% when compared against a single-mass hybrid energy harvester. A comparative study showed that the L-vertical and vertical bluff-body-tuned was the best performing hybrid-PE energy harvester based on total voltage output.

“…However, the main advantages of piezoelectric-based devices are the simple nature of piezoelectric transducers, which enable designers to use a simple mechanism in the harvester, in addition to their durability, high voltage, high impedance of output, and high energy production density [ 25 , 26 ]. Some vibrational energy converters use a combination of the aforementioned transducers to reach a higher conversion efficiency [ 27 ].…”

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.
