Remote control device including a power accumulating device

The device has an electrical energy accumulation device comprising a capacitor (C1) connected to energy generating terminals i.e. electromagnetic or piezoelectric induction type energy generators (1), and a switch (S1) for controlling charge/discharge of the capacitor. The electrical energy accumulation device comprises another capacitor (C2) connected to the former capacitor, and another switch (S2) controlling charging /discharging of the latter capacitor. A sequential control unit successively controls the switches.
