Abstract

This paper presents a novel energy harvesting circuitry for a self-biased piezoelectric suitable for battery-less sensors in remote applications. The presented self-biased energy harvesting circuit does not require any external DC bias. The DC bias required to switch a transistor is granted from the electronic oscillator that is biased through the piezoelectric converted energy. The amplified output voltage utilizing a DC to DC boost converter with maximum power efficiency at the output has been fabricated using PCB board. The circuit is composed of a full wave bridge rectifier, smoothing capacitor, switch mode DC/DC Boost converter and a storage component at the output terminal. The measured harvested power is of 300 micro watts at load of 1.2M ohms used for ultra-low power applications.
