Wind energy harvesting technology can convert wind energy into electric energy to supply power for microelectronic devices. It has great potential in many specific applications and environments, such as remote areas, sea surfaces, mountains, and so on. Over the past few years, flutter‐based wind energy harvesting, which generates electric energy based on the limit cycle oscillation created by structural aeroelastic instability, has received increasing attention, and as a consequence, different energy harvesting structures, theories, and methods have been proposed. In this paper, three types of flutter‐based energy harvesters (FEHs) including airfoil‐based, flat plate‐based, and flexible body‐based FEHs are reviewed, and related concepts and theoretical models are introduced. The recent progress in FEH performance enhancement methods is classified into structural improvement and optimization, the introduction of nonlinearity, and hybrid structures and mechanisms. Finally, the main FEH challenges are summarized, and future research directions are discussed.

Technology advancement in power–electronic interfaces and their evolution open an opportunity to end-users to benefit from their newfound capability. For the end-users, power–electronic interfaces can act as Distributed Energy Resources (DERs) for reactive power injection and absorption. If these power–electronic interface capabilities can be properly integrated into traditional utility system operations, they can be used as beneficial tools for distribution management and voltage profile enhancement. Considering the present distribution system, it is not possible to communicate to all DERs. In this paper, we considered two proposed residential-control and droop-control methods. The multi-criteria decision-making technique (MCDM), along with fuzzy theory, was used to prioritize candidate buses for their participation in the Volt-VAR program. In this paper, the contribution of active DERs in reactive power compensation was evaluated.

Ocean contain abundant clean energies including tidal and wave, but such energies are known for low frequency and large excitation amplitude, posing considerable challenges for high‐efficiency energy conversion. As an emerging technology, triboelectric nanogenerators (TENGs) have been widely used in energy harvesting and novel sensor design due to their high sensitivity and flexible structure. Meanwhile, they show great advantages in the low‐frequency environment (<5 Hz), and display great potential for deployment in remote ocean waters, and construction of large‐scale TENG networks. In this review, firstly, the working principle of TENGs and various configurations developed for the marine environment are introduced, which mainly include solid–solid and solid–liquid interfaces. Then, from the viewpoint of power improvement, authors are most concerned about the modification methods of materials such as surface modification, electron injection, and chemical doping. Meanwhile, improved technologies for energy harvesters in marine environment are discussed in detail, such as improving the hydrophobicity and degradation of materials, studying the self‐healing ability of materials, and designing power management circuits. Finally, the current challenges are summarized, and research trends are given from both short‐term and long‐term perspectives.
