Abstract

A digital energy harvester that captures electrical energy from complicated random or multimodal vibrations is proposed. The novel energy harvester is digital, autonomous, and controlled by a self-powered microprocessor. The digital self-powered microprocessor automatically and synchronously changes the circuit components with the vibration phase, and can therefore achieve autonomous harvesting. The multifunctional and self-controlled microprocessor is only driven by the voltage of the piezoelectric transducer, and no external power is required. The harvester exhibits great potential and versatility and is applicable to many machines and devices.
