An energy-scavenging interface (24) having input terminals (25', 25") that can be connected to a transducer (22) including a storage element (22b), for receiving an input signal (V IN ) , and output terminals (26', 26"), which can be connected to an electrical load (27, 28) for supplying to the electrical load an output signal (V OUT ), said energy-scavenging interface (24) comprising: a first switch (30), which receives a signal that is a function of the electrical input signal (V IN , I); a first current-conduction element (36); and a control logic (60) configured for: (a) closing the first switch (30) for a first time interval having a first duration (T DELAY ) proportional to a time constant (Ä TRANSD ) of the transducer (22), during which the storage element (22b) stores the electrical charge; (b) opening the first switch (30) for a second time interval subsequent to the first time interval, in which the electrical load is supplied through the first current-conduction element by means of the electrical charge stored in the storage element, and until the electrical energy accumulated by the storage element (22b) reaches a first threshold value (I TH ).
