A measurement bench has been developed to fully automate the procedure for the characterization of a vibration-based energy scavenging system. The measurement system is capable of monitoring all important characteristics of a vibration harvesting system (input and output voltage, current, and other parameters, frequency and acceleration values, etc.). It is composed of a PC, typical digital mea...

A micro power generator for harvesting vibration energy by means of a piezoelectric laminated cantilever with inertial mass was designed, fabricated, and characterized. The device was micro machined from a silicon-on-insulator structure coated with a 2μm thick piezoelectric PZT thin film. Interdigitated electrodes (IDE) were applied to achieve higher voltages. A piezoelectric coupling constant ...

We have examined a piezoelectric unimorph cantilever (PUC) with unequal piezoelectric and nonpiezoelectric lengths for vibration energy harvesting theoretically by extending the analysis of a PUC with equal piezoelectric and nonpiezoelectric lengths. The theoretical approach was validated by experiments. A case study showed that for a fixed vibration frequency, the maximum open-circuit induced ...

Address correspondence to [email protected] ABSTRACT In this article, an introduction is presented about the energy harvesting technologies that have potential for powering nanosystems. Our discussion mainly focuses on the approaches other than the well-known solar cell and thermoelectrics. We mainly introduce the piezoelectric nanogenerators developed using aligned ZnO nanowire arrays. This is...

This paper presents a planar multi-pole electromagnetic energy harvesting transducer. We report on the design, manufacture, and performance results of integrated devices based on this transducer. The transducer leverages recent advancements in the manufacture of multi-pole magnets and can be implemented in a very cost effective manner using printed circuit board (PCB) technology. The basic tran...
