“…With DE, electric power can be generated even by a slow change in the shape of DE [8,10], while for piezoelectric devices higher-frequency impulsive mechanical forces are needed to generate the electric power [6]. Also, the amount of electric energy generated on a per mass basis and conversion efficiency from mechanical to electrical energy can be greater than that from piezoelectricity [9,25,26]. We can calculate the energy generated for such a cycle.…”

“…Energy harvesting systems can use piezoelectric materials. Due to the nature of the piezoelectric response, and the cost of the materials, these generators tend to be used only for small devices that harvest energy from higher frequency sources such as mechanical vibrations [6][7][8][9]. Wave power generators using DE (dielectric elastomer) transducers, a novel method to harvest renewable energy [10,11], also known as "artificial muscles" because of their functional similarity to natural muscles when operated in reverse as actuators, may be able to solve these problems.…”

DEs (dielectric elastomers), a type of electroactive polymer, show considerable promise for harvesting energy from wind, ocean waves, water currents, or even from human motion. Their energy density and efficiency of conversion make for simple, low cost, and robust generators where an electroactive polymer transducer is directly driven by the up-and-down motions of waves. Over the past few years, we have conducted various tests to validate DE wave power generators. In our 2010 test, a DE generator generated electricity even with comparatively small wave heights. Generator performance over a longer period of time (50 minutes) was evaluated in our present test. In the 2010 test, the system was not able to automatically respond to changes in sea level because of its mooring. The present system used a sunken horizontal plate, which enabled it to create the needed reaction forces and respond to sea level changes. This method of mooring generated electric power even in deep water.

“…(2), we can now write this value as: E = 0.5 C 1 V 1 2 (C 1 /C 2 -1) (3) The amount of energy that a given mass of DE can generate is determined by its maximum strain and dielectric breakdown strength. Using polymer materials such as acrylic and silicone elastomers, energy densities more than an order of magnitude greater than those of piezoelectric or electromagnetic materials have been produced [4,[21][22][23][24].…”

“…Rapid deformation is not necessary as in the case of a piezoelectric element. Thus, unlike piezoelectric devices [4,[21][22][23][24], a DE device can be directly coupled to relatively low frequency motions such as human activity or ocean waves where stretch and contract times are on the order of tenths of seconds to tens of seconds rather than milliseconds [25].…”

Abstract:From 2007 to 2015, we installed DE (dielectric elastomer) generators on a buoy, and succeeded in a demonstration of power generation at sea. In 2011, we also pointed out that DE generators could be useful for ships for the first time in the world. Using the know-how obtained at that time, we have recently developed an innovative wave-power generator for small ships, which can generate electric power by the rocking movement of the ship. Mounting this device on a model ship, we carried out a demonstration experiment of the power generation in a wave-generation water-tank to verify its feasibility for practical use on a real ship. And 48% of wave energy (gross value) can be converted to electric energy, suggesting the realization of fairly high efficiency power generation, compared with the efficiency of the existing wave generators.

Multifunctional materials support many technological advances in materials science required by the increasing interactivity demand of the Internet of Things (IoT). [1] Among multifunctional materials, smart materials allow their implementation as sensing materials as they transduce different physicoÀchemical solicitations. Those materials include piezoelectric, pyroelectric, magnetostrictive, magnetoelectric, or shape memory materials, among others. [2] Electroactive polymers (EAPs) and their composites are an important class of smart materials applied in technological applications such as sensors and actuators, [3] biomedical, [4] environmental, [5] and energy harvesting [6] and storage applications, [7] among others, based on their active response but also on their tailorable mechanical, thermal, and chemical properties and versatility with respect to the processing techniques, including compatibility with additive manufacturing technologies.Within the EAP class, poly(vinylidene fluoride) (PVDF) and their copolymers are the most relevant for many piezo-, pyro-, and ferroelectric applications and stand out in comparison with other polymers for their higher dielectric constant and piezoelectric coefficient,
