A capacitive driving system (100) comprises: - a supply device (110) having a set of transmission electrodes (111, 112) located at a top surface (117), and a power generator (13) adapted to generate alternating electrical power; - load devices (200) each having two receiver electrodes (221, 222) at a lower surface (227) and at least one load member (223) coupled to said receiver electrodes. In an energy transfer position, the lower surface of the load device is directed to the top surface of the supply device and at least one of said transmission electrodes together with a corresponding one of said receiver electrodes defines a first transfer capacitor (31). Resonant energy transfer takes place from the supply device to the load member. The load device can be rotated for enabling amendment of the capacitance value of said first transfer capacitor. |
