Original Abstract Submitted
Disclosed is an energy autonomous system including an energy transducer, a first capacitor, a second capacitor having greater capacitance than the first capacitor, and a microprocessor. The microprocessor includes a first terminal electrically coupled to the energy transducer and the first capacitor; a second terminal electrically coupled to the second capacitor; a switch that is in a conductive state in which the switch electrically couples the first terminal and second terminals together, or a nonconductive state in which the switch does not electrically couple first terminal and second terminals together; a voltage detector that detects a voltage at the first terminal; and a processor coupled to the voltage detector and the switch. The processor controls charging of the second capacitor by controlling the switch to be in the conductive state or the nonconductive state based on the voltage at the first terminal detected by the voltage detector.
