“…For example, SARTI Research group from the electronics department of the Universitat Politèc-nica de Catalunya performed some experiments to evaluate a developed energy harvesting device based on VIV (Molino- Minero-Re et al 2012). Also, Progeny systems corporation and the center for Energy Harvesting Materials and Systems at Virginia Tech worked on designing a sea floor power supply that can drive low-power electronics such as oceanographic sensors and health monitoring systems (Bezanson et al 2010).…”

Piezoelectric materials directly convert strain energy into electric energy and vice versa and are commonly used in sensing and actuating applications. They have been employed in mediums frequently undergoing vibrations, allowing harnessing of power at a small scale. Ideas of using the piezoelectric effect as a power take-off mechanism for ocean energy emerged in the 1970s and are still at a developing stage. This article overviews recent development on the application of the piezoelectric processes to the ocean field and provides a building block for future research work of ocean engineers who are interested in such possibilities. A brief discussion on the selection of the piezoelectric materials for different ocean-engineering applications is presented. Significant research projects on ocean-energy extraction through the use of these materials are then described and discussed with special scrutiny on the viability of proposed designs and their experimental or numerical validation. Various harvesting techniques in an ocean environment are categorized and compared. The challenges ahead and the outlook for success in this area are outlined.

“…There are a variety of potential methods to couple the flow energy to the structure with the transduction mechanism located away from the flow. Several types of flow induced energy harvester methods were considered in this study; one is a hydraulic pressure based method [18,24], a second is a bluff body based method [12,13,14,15,16], yet another is based on leakage-flow instabilites which induce large displacements in the bimorph tip when fluid flows past a narrow passage [25]. For example, when the flow is passing through the nozzle, the pressure fluctuation forces the bimorph to move alternately up and down, creating internal stresses and producing electricity.…”

“…In addition, they can operate with limited strain and in non rotating systems which offers the potential to produce long life harvesting systems due to limited wear, and piezoelectric materials with large piezoelectric activity and with Curie temperatures in the 300 o C range are commercially available so the potential to operate at higher temperatures is also an advantage. A variety of studies have looked at methods to convert flow energy into vibrations including vortex shedding [12,13,14,15,16], flapping motions [17] and hydraulic pressure [18]. This paper presents the results of our experiments on a variety of designs for flow energy harvesters which used nozzles and/or flow cavities along a pipe to produce conditions that excite a vibrating piezoelectric structure.…”

There is a need for a long-life power generation scheme that could be used downhole in an oil well to produce 1 Watt average power. There are a variety of existing or proposed energy harvesting schemes that could be used in this environment but each of these has its own limitations. The vibrating piezoelectric structure is in principle capable of operating for very long lifetimes (decades) thereby possibly overcoming a principle limitation of existing technology based on rotating turbo-machinery. In order to determine the feasibility of using piezoelectrics to produce suitable flow energy harvesting, we surveyed experimentally a variety of nozzle configurations that could be used to excite a vibrating piezoelectric structure in such a way as to enable conversion of flow energy into useful amounts of electrical power. These included reed structures, spring mass-structures, drag and lift bluff bodies and a variety of nozzles with varying flow profiles. Although not an exhaustive survey we identified a spline nozzle/piezoelectric bimorph system that experimentally produced up to 3.4 mW per bimorph. This paper will discuss these results and present our initial analyses of the device using dimensional analysis and constitutive electromechanical modeling. The analysis suggests that an order-of-magnitude improvement in power generation from the current design is possible.

“…Akaydin, H. D. [3] carried out experiment for a piezoelectric energy harvesting device which has a hollow cylinder with a diameter of 19.8mm and a single cantilever beam in a wind tunnel. Erik Molino-Minero-Re [4] implemented the VIV energy harvesting experiment for piezoelectric device with a series of cylinder and single cantilever beam, and the result shown that the maximum power is about 0.31 muW when the cylinder diameter is 8mm. A. Mehmood [5] calculated the VIV piezoelectric energy harvesting under low Reynolds and high mass ratio, and the maximum power is 10μW.…”

Abstract. The WIV numerical simulations of an elastically mounted cylinder located downstream of a stationary larger cylinder at high Reynolds numbers is done by lattice Boltzmann method(LBM). The model of fluid-mechanical-electric is established by LBM and OpenModelica through the coupling of WIV equation and Gauss equation. The numerical analysis of the WIV piezoelectric energy harvesting obtain the output voltage and output power under R=2e5Ω, which is compared to the numerical simulation of a single cylinder VIV piezoelectric energy harvesting. The results show that the WIV increases the amplitude of downstream cylinder and gets higher output voltage and power. For the same energy harvesting device, WIV has better electricity-generating capacity and can effectively improve the piezoelectric output characteristics.
