In the current era of the industrial revolution 4.0, the need for time, labor, and cost efficiency is a basic requirement for human life, especially regarding electrical energy sources. The supply of commercial electricity is still using electricity cables to deliver electricity to the load. Therefore, one of the ways of sending or transferring electrical power that continues to be developed today is wireless electricity transfer. The wireless transfer of electric power has several advantages compared to the use of cables, which can increase the convenience in the use of electrical equipment and can reduce the amount of electronic waste. This research will study the techniques or methods of near-field wireless energy transfer systems, namely the inductive coupling method, the magnetic resonance coupling method and the capacitive coupling method. The results of this study propose an optimal modeling of wireless power transfer so that results and quality are better, taking into account the distance between the sender and receiver because the work efficiency of wireless power transfer decreases with respect to distance. And the signal transmission frequency is low for inductive coupling, while the resulting frequency will be high on magnetic resonance coupling and capacitive coupling. AbstrakDi era revolusi industri 4.0 saat ini, kebutuhan akan hal efisiensi waktu, tenaga kerja, dan biaya merupakan kebutuhan pokok bagi kehidupan manusia, khususnya yang menyangkut sumber energi listrik. Suplai energi listrik komersial sampai saat ini masih mempergunakan kabel listrik untuk menghantarkan listrik ke beban. Salah satu cara pengiriman daya yang terus dikembangkan oleh peneliti saat ini adalah pengembangan sistem daya listrik nirkabel, yang memiliki kelebihan dalam pemanfaatannya dibandingkan dengan kabel. Kenyamanan peralatan listrik tanpa kabel yang dirasakan oleh pengguna dan berkurangnya sampah listrik yang ditimbulkan, merupakan kelebihan sistem transfer daya nirkabel. Pada penelitian ini akan dikaji mengenai teknik atau metode sistem transfer daya nirkabel medan dekat (near field), yaitu metode kopling induktif, metode kopling resonansi magnetik dan metode kopling kapasitif. Hasil penelitian ini mengusulkan pemodelan transfer daya nirkabel secara optimal agar hasil dan kualitasnya lebih baik, dengan memperhatikan jarak antara pengirim dan penerima karena efisiensi kerja transfer daya nirkabel berkurang terhadap jarak. Dan frekuensi sinyal transmisi rendah untuk kopling induktif, sementara frekuensi yang dihasilkan akan tinggi pada kopling resonansi magnetik dan kopling kapasitif. Kata kunci : transfer daya nirkabel, kopling kapasitif, kopling resonansi magnetik, kopling induktif

“…Special outdoor applications are also used, such as wireless charging for electric trams and vehicles; furthermore, power supply for running cars may be used [36,37]. In addition, WPTs can be used in medical applications as a power supply for a capsule endoscope for diagnosis gastroenterologists [38], as well as other devices implanted under the human skin, such as cardiac implants [39]. Tower and transmission lines can be inspected based on UAVs.…”

Abstract:Traditional power supply cords have become less important because they prevent large-scale utilization and mobility. In addition, the use of batteries as a substitute for power cords is not an optimal solution because batteries have a short lifetime, thereby increasing the cost, weight, and ecological footprint of the hardware implementation. Their recharging or replacement is impractical and incurs operational costs. Recent progress has allowed electromagnetic wave energy to be transferred from power sources (i.e., transmitters) to destinations (i.e., receivers) wirelessly, the so-called wireless power transfer (WPT) technique. New developments in WPT technique motivate new avenues of research in different applications. Recently, WPT has been used in mobile phones, electric vehicles, medical implants, wireless sensor network, unmanned aerial vehicles, and so on. This review highlights up-to-date studies that are specific to near-field WPT, which include the classification, comparison, and potential applications of these techniques in the real world. In addition, limitations and challenges of these techniques are highlighted at the end of the article.

Recently, the capsular endoscope that has extra function has been investigated. Although the power consumption tends to increase as the ability increases, it is difficult to increase the capacity of the battery due to the volumetric problem. In this study, we proposed an antenna for both wireless power transmission and image transmission to be mounted on a capsule endoscope. In this paper, we discussed the requirements desired to antennas to be mounted in capsular endoscope.
