Kertas kerja ini membentangkan kebolehlaksanaan pengganding kapasitif menggunakan lapisan dua elektrik untuk pemindahan kuasa tanpa wayar di bawah air laut. Oleh kerana air laut ialah larutan elektrolit, lapisan berkembar elektrik (EDL) terbentuk pada permukaan elektrod pengganding dalam arus terus. Jika EDL boleh digunakan dalam frekuensi radio, ada kemungkinan kecekapan pemindahan kuasa tinggi boleh dicapai di bawah air laut kerana Q-faktor boleh diperolehi. Untuk menjelaskannya, langkah-langkah berikut perlu diambil; Pertama, ukur ciri kekerapan kebolehterimaan kompleks dalam air laut dan jelaskan tingkah laku EDL daripada keputusan. Kedua, jelaskan bahawa EDL membawa kepada peningkatan dalam Q-faktor air laut. Ia akan ditunjukkan dalam kertas ini bahawa gandingan kapasitif oleh EDL berlaku menggunakan dua jenis model pengganding. Ketiga, reka bentuk pengganding dengan kecekapan tinggi seperti yang diukur oleh Q-faktor dan kebenaran relatif EDL. Terakhir, tunjukkan bahawa pengganding yang direka bentuk di bawah air laut boleh mencapai kecekapan lebih 85% pada jarak pemindahan 5 mm dan kebolehlaksanaan pengganding dengan EDL.

Abstract: This paper presents the feasibility of a capacitive coupler utilizing an electric double layer for wireless power transfer under seawater. Since seawater is an electrolyte solution, an electric double layer (EDL) is formed on the electrode surface of the coupler in direct current. If the EDL can be utilized in radio frequency, it is possible that high power transfer efficiency can be achieved under seawater because a high Q-factor can be obtained. To clarify this, the following steps need taking; First, measure the frequency characteristics of the complex permittivity in seawater and elucidate the behaviors of the EDL from the results. Second, clarify that EDL leads to an improvement in the Q-factor of seawater. It will be shown in this paper that capacitive coupling by EDL occurs using two kinds of the coupler models. Third, design a coupler with high efficiency as measured by the Q-factor and relative permittivity of EDL. Last, demonstrate that the designed coupler under seawater can achieve over 85% efficiency at a transfer distance of 5 mm and feasibility of the coupler with EDL.
