Ceramic Based Intelligent Piezoelectric Energy Harvesting Device

A Piezoelectric Device for Measurement and Power Harvesting Applications

With the fast growth of wireless communications between nodes/sensor units, devices installed in remote places require power energy supply solutions to assure their functionally and data communication capabilities. For these applications energy harvesting takes place as a good solution, to increase the availability of energy, in opposition to the conventional systems of energy supply. Regenerat...

A periodic folded piezoelectric beam for efficient vibration energy harvesting

Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...

Piezoelectric Transformers for Ultra-low Voltage Energy Harvesting Applications ¬リニ

This work shows the possibility to exploit piezoelectric transformers (PTs) for implementing step-up oscillators for ultra-low DC voltage energy harvesting (EH) applications. Oscillation is achieved by coupling a common source stage made up of nchannel JFETs with a piezoelectric transformer acting like a high gain notch filter. A voltage doubler is used to store energy in a capacitor. A mathema...
