“…In addition to tank testing, numerical models of the fluid structure interaction of the S3 device with the waves were set up, [ 159 ] dry‐run generation tests on the DEG modules along with reliability tests were conducted, [ 49 ] and layouts of scalable power electronics were identified (Section 3.3). [ 125 ] As an important conclusion, the authors suggested that the peak electric field to be cyclically applied on the DE material should be significantly lower than the BD value (they suggest a value of 60 kV mm −1 for silicones), for the system to reach a target lifetime on the order of 20 years (i.e.,

Dielectric elastomer generator systems (DEGSs) are a class of electrostatic softtransducers capable of converting oscillating mechanical power from different sources into usable electricity. Over the past years, a diversity of DEGSs has been conceived, integrated, and tested featuring diverse topologies and implementation characteristics tailored on different applications. Herein, the recent advances on DEGSs are reviewed and illustrated in terms of design of hardware architectures, power electronics, and control, with reference to the different application targets, including large-scale systems such as ocean wave energy converters, and small-scale systems such as human motion or ambient vibration energy harvesters. Finally, challenges and perspectives for the advancement of DEGSs are identified and discussed.

“…In 2011, a 10 m long S3 WEC, equipped with 20 independent EAP generators, was tested in the Hydrodynamics and Ocean Engineering Tank of Ecole Centrale de Nantes. Numerical tools were developed to analyse the hydroelastic response of the device [90]. A recent mathematical model has also provided a means to calculate the maximal power absorption of the device based on the waves radiated in the far field.…”

We review wave energy conversion technologies for niche applications, i.e., kilowatt-scale systems that allow for more agile design, faster deployment and easier operation than utility scale systems. The wave energy converters for niche markets analysed in this paper are classified into breakwater-integrated, hybrid, devices for special applications. We show that niche markets are emerging as a very vibrant landscape, with several such technologies having now achieved operational stage, and others undergoing full-scale sea trials. This review also includes flexible devices, which started as niche applications in the 1980s and are now close to commercial maturity. We discuss the strong potential of flexible devices in reducing costs and improving survivability and reliability of wave energy systems. Finally, we show that the use of WECs in niche applications is supporting the development of utility-scale projects by accumulating field experience, demonstrating success stories of grid integration and building confidence for stakeholders.

The dielectric elastomer generator (DEG) has attracted attention in converting mechanical energy into electrical energy, due to its high energy density, fast response, and light weight, which together make DEG a promising technology for electromechanical conversion. In this article, recent research papers on DEG are reviewed. First, we present the working principles, parameters, materials, and deformation modes of DEG. Then, we introduce DEG prototypes in the field of collecting mechanical energy, including small-scale applications for wind energy and human motion energy, and large-scale applications for wave energy. At the end of the review, we discuss the challenges and perspectives of DEG. We believe that DEG will play an important role in mechanical energy harvesting in the future.
