Implementation of curcumin concentration coating to improve power efficiency in wireless power transfer

The research object in this research is the copper winding in the WPT system which characteristics will be observed after being coated with a concentration of curcumin. From the experiment of coating the curcumin concentration: H2O on the surface of the copper coil, it shows that there is an influence of physical phenomena from the curcumin concentration material. The strength of the magnetic field (B) and electric current (I) increased after the process of coating the concentration of curcumin: H2O on the copper coil for 0–5 hours. A coil wound with an electric current produces a strong magnetic field (B1), while the curcumin compound (C20H21O6) contains two aromatic benzene rings which produce a strong magnetic field on 6p (B2). Measuring the magnetic field strength using a Gauss meter after the curcumin concentration coating process showed an increase in the magnetic field strength and electric current. Assuming the equation for magnetic field strength B=B1+B2. Increasing the strength of the magnetic field and electric current in the copper winding of the wireless power transfer (WPT) system will affect the power efficiency of the copper windings L1 (transceiver) and L2 (receiver). The process of coating curcumin on a layer of copper to determine the electromechanical effect of curcumin. Utilization of curcumin as an alternative to increase power efficiency in WPT and increase conductivity in copper windings
