 Wireless Power Transfer (WPT) can be implemented in many ways. The most well-known technologies in the sector today are depicted in Figure 1 and can be divided into WPT by acoustic or by electromagnetic means Wireless Power Transfer (WPT) can be implemented in many ways.

 The inductive coupling technology attains the highest energy transfer efficiency, varying from 70% up to 90%. In the same figure can be seen that the efficiency for magnetic resonant coupling strongly declines to a range of 40-60%. In the near-field technology this WPT method is used for greater distances, going from a few centimetres up to a maximum of 5m. A summary of these near-field methods is given in Figure 3. The inductive coupling technology attains the highest energy transfer efficiency, varying from 70% up to 90%.
