The introduction of the wireless power energy transmission with the green energy harvesting. Instead of creating the antenna array, the pivoting antenna (coil) structure can be used to implement the single antenna (coil) with different area or size of antenna (coil) and different turns of coil. The power energy can be transmitted wirelessly by various designed antenna (coil). By connecting to the proposed cuttable-flexural substrate power chager circuit, the original and traditional battery (ex. mercury battery) can be replaced. The size of the IOT devices can be reduced.
