    Abstract: Systems and techniques are provided for a power receiver circuit. A power generating mechanism may include power generating elements that may generate alternating current signals. Rectifier circuit may include rectifiers that may generate a direct current signal from an alternating current signal, and diodes. Group circuits that may connect groups of rectifier circuits in electrical circuits to combine the direct current signals from the rectifier circuits in a group into a single direct current signal. A step down converter may be connected to the group circuits. The step down converter may convert a direct current signal to a direct current signal of a target voltage level. An output switch may be connected to the step down converter. A linear regulator may be connected to the step down converter. A microcontroller may be connected to the linear regulator and the output switch and may control the output switch.

    Abstract: Systems and techniques are provided for a self-powered energy harvesting circuit. A power generating mechanism may include power generating elements that generate alternating current signals. Rectifier circuits may each include a rectifier that generates a direct current signal from an alternating current signal. Group circuits may connect 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. Energy storage devices may be connected to the group circuits. The outputs of energy storage devices may be combined into a single output. The single output split into a primary output and a secondary output. A switch may be connected to the primary output. A controller may be connected to the secondary output and to the switch. The controller may control the switch. A voltage regulator may be connected to an output of the switch.

    Abstract: Electrical power for an electrical device can be acoustically produced. A first portion of an acoustic energy can be received at a piezoelectric transducer. A first electrical energy, produced from the first portion of the acoustic energy, can be conveyed from the piezoelectric transducer and received by a circuit. A bias voltage, produced from the first electrical energy, can be conveyed from the circuit and received at a capacitive transducer. A second portion of the acoustic energy can be received at the capacitive transducer. A second electrical energy, produced from the second portion of the acoustic energy, can be conveyed from the capacitive transducer and used as the electrical power for the electrical device. A ratio of the second electrical energy to the second portion of the acoustic energy can be greater than a ratio of the first electrical energy to the first portion of the acoustic energy.
