“…In the early 1980s, McKinney et al [1] proposed a prototype energy power-generating device based on the flutter phenomenon. Ericka et al [2] proposed an energy-harvesting generator from vibration using a piezoelectric membrane. Under an acceleration of 2 g and a load resistance of 56 kΩ, the energy-harvesting generator generated a maximum power of 1.8 mW.…”

This paper presents a new energy-harvesting system with two identical piezoelectric energy harvesters in a tandem configuration. Each harvester consists of a piezoelectric beam and a circular cylinder. Experiments are performed to investigate the energy-harvesting performances of this system in water. It can be found that their energy-harvesting performances are all different from that of the single harvester (without an upstream or downstream harvester). The experimental results show that the water speed and the spacing ratio have significant effects on the energy-harvesting performances of the two tandem harvesters. The output power of the upstream harvester first increases, and then decreases with the water speed increasing. The maximum output power of 167.8 µW is achieved at the water speed of 0.306 m/s and the spacing ratio (L/D) of 2.5. Increasing the water speed results in an increase in the energy performance of the downstream harvester. Compared with the single harvester, the performance of the downstream harvester is weakened in the low water speed range, but enhanced in the higher water speed range. Further, the output power of 533 µW is obtained by the downstream harvester at the water speed of 0.412 m/s and the spacing ratio of 1.7, which is 29 times more than that of the single harvester. The results indicate the superiority of the two tandem harvesters in energy-harvesting performance.

The paper deals with the experimental methods of determination of piezoelectric unimorph resonant frequencies essential for a design of acoustical systems. The characterization of piezoelectric unimorphs and their significant properties are brought in. Three broadband methods of determination of unimorph frequency response based on measurement of electrical impedance, acoustic pressure and vibration velocity are presented. The supposed methodology is verified by measurement of three unimorph samples. The efficiency and practical applicability of each method are further discussed.

“…Different from a strip that primarily deforms along its axis, an annular geometry deforms in two-dimensions, thus offering a further degree of freedom for design of energy harvesting devices [23,25,45]. The possibility of harvesting energy from the base excitation of annular IPMCs may aid in the design of miniature selfpowered devices for installation in instrumented buoys that could extract energy from the up-and-down movements of the ocean [46,51].…”

Energy harvesting from underwater vibration of an annular ionic polymer metal composite

2015

In this paper, we study underwater energy harvesting from bending vibrations of an annular ionic polymer metal composite (IPMC). The IPMC is clamped to a moving base, which harmonically excites the IPMC to vibrate along its fundamental axisymmetric mode shape. We model the IPMC as a thin plate, and the interaction with the surrounding fluid is described through a distributed hydrodynamic loading which is responsible for a marked reduction of the resonance spectrum through added mass effect. IPMC sensing is described though a lumped circuit model, comprising a resistor, a capacitor, a Warburg impedance, and a voltage source controlled by the mechanical curvature. In a series of experiments, the IPMC electrodes are shunted with a resistor, which is parametrically varied together with the excitation frequency to elucidate power harvesting. We also assess the effect of the IPMC geometry on power harvesting, by systematically varying the inner radius of the annulus to encompass five different configurations. Experimental results suggest that IPMC geometry has a primary role on its vibrations, whereby increasing the inner radius results into a significant increase of the resonance frequency. Such an increase does, in turn, produce a robust improvement in power harvesting that increases of two orders of magnitude as the ratio between the inner and the outer radius varies from 0.23 to 0.5.
