Modeling and Simulation of Piezoelectric Energy Harvesting

Energy harvesting has received growing attention over the last decade. The research motivation in this field is due to the reduced power requirement of small electronic components, such as the wireless sensor networks used in structural health monitoring applications. The ultimate goal in this research field is to power such small electronic devices by using the vibration energy available in th...

Energy Harvesting Electrical from Nano Beam with Layer Piezoelectric under Random Vibration

In the present paper, electrical energy harvesting from random vibrations of an Euler-Bernoulli nano-beam with two piezoelectric layers is investigated. The beam is composed of an aluminum layer together with two piezoelectric ceramic layers (PZT 5A) serving as energy harvesting sensors. In the proposed method, the equations governing the bimorph nano-beam will be analytically derived using cla...

Calvarial bone harvesting with piezoelectric device.

We introduce the use of a piezoelectric device in order to harvest calvarial bone grafts. The vibration frequency of the instrument allows for the efficient cutting of bone without the risk of accidentally damaging the dura.

Piezoelectric Energy Harvesting

The piezoelectric material selection and the circuit design in vibrational energy harvesting are discussed. The performances of the energy-harvesting unimorph devices that captured frequencies of 60 Hz by using piezoelectric PZT-based and BT-based ceramics were evaluated. Output voltages and power from the devices depend on the amplitude and the frequency of the oscillations, and depend on the ...
