Self-powered energy harvesting circuit

A self-powered energy harvesting circuit device comprising:

• a power generating mechanism comprising power generating elements configured to generate alternating current signals;
• one or more rectifier circuits connected to the power generating elements, each of the rectifier circuits comprising a rectifier configured to generate a direct current signal from the alternating current signals generated by the power generating elements;
• one or more group circuits, each of the group circuits connecting a group of the rectifier circuits in an electrical circuit to combine the direct current signals from the rectifier circuits in the group into a single direct current signal;
• one or more energy storage devices, each of the energy storage devices connected to at least one of the group circuits, wherein the one or more energy storage devices store energy carried by the direct current signals output by the one or more group circuits, the outputs of the one or more energy storage devices combined into a single output carrying a direct current signal, the single output split into a primary output carrying a direct current signal and a secondary output carrying a direct current signal;
• a switch connected to the primary output and comprising an output that carries the direct current signal from the primary output when the switch is closed;
• a controller connected to the secondary output and to the switch, and operating using the direct current signal carried by the secondary output, and configured to control the switch based on a level of energy stored in the energy storage devices;
• and
• a voltage regulator connected to the output of the switch and comprising an output that carries a direct current signal converted from the direct current signal from the output of the switch to a voltage for an electrical load when the switch is closed.
