  • Electronic circuit for harvesting energy from ultra-low power sources
    Patent number: 10734822
    Abstract: The present invention relates to an electronic circuit for harvesting energy from ultra-low power sources, said circuit comprising a capacitor module (1), a microcontroller (2), two analog switches (3 and 7), an auxiliary battery module (4), a terminal (5), and an operating mode module (6). The circuit is characterised in that: at least two sources (FE) from a plurality of sources (FE) are connected to the capacitor module (1); and the microcontroller (2) transmits the RC digital signals [1.4] at the capacitor module (1) to the first set of analog switches and changes from an idle state to an active state.
