Special Issue Information

Dear  Colleagues,

This Special Issue, "Energy Harvesting and Storage Devices in Korea", features research articles from top researchers in the field of energy harvesting and storage devices, with a particular focus on developments in Korea. This Special Issue covers a wide range of topics related to the design, development, and application of energy harvesting and storage devices, providing a comprehensive overview of the latest research in the field.

Energy harvesting and storage devices are becoming increasingly important as the world seeks to transition to cleaner and more sustainable sources of energy. These devices are used to capture and store energy from renewable sources, such as solar, wind, and thermal energy, and can be used to power a wide range of applications across various industries.

The articles in this Special Issue cover a broad range of topics related to energy harvesting and storage devices, including their design, development, and performance evaluation. For example, one article discusses the development of a hybrid energy harvester that combines piezoelectric and electromagnetic mechanisms to capture energy from ambient vibrations. Another article describes the design and optimization of supercapacitor-based energy storage devices.

In addition to showcasing the latest research in the field, this Special Issue also highlights the current challenges and opportunities in energy harvesting and storage devices. For example, several articles discuss the limitations of existing energy harvesting and storage technologies and propose new solutions to overcome these limitations. Other articles focus on the commercialization and scaling up of energy harvesting and storage devices to meet the growing demand for sustainable energy solutions.

Overall, the Special Issue "Energy Harvesting and Storage Device in Korea" provides a comprehensive overview of the latest developments in energy harvesting and storage devices, and highlights the potential of these technologies to revolutionize the way we capture, store, and use energy.

As an urgent international challenge, the sudden change in climate due to global warming needs to be addressed in the near future. This can be achieved through a reduction in fossil fuel utilization and through carbon sequestration, which reduces the concentration of CO2 in the atmosphere. In this study, a self-sustainable impact sensor is proposed through implementing a triboelectric nanogenerator with a CaCO3 contact layer fabricated via a CO2 absorption method. The triboelectric polarity of CaCO3 with the location between the polyimide and the paper and the effects of varying the crystal structure are investigated first. The impact sensing characteristics are then confirmed at various input frequencies and under applied forces. Further, the high mechanical strength and strong adherence of CaCO3 on the surface of the device are demonstrated through enhanced durability compared to the unmodified device. For the intended application, the as-fabricated sensor is used to detect the turning state of the paper Ddakji in a slap match game using a supervised learning algorithm based on a support vector machine presenting a high classification accuracy of 95.8%. The robust CaCO3-based triboelectric device can provide an eco-friendly advantage due to its self-powered characteristics for impact sensing and carbon sequestration. Full article
