Direct piezoelectric conversion is very popular in generating power from mechanical stress. There continuous progress harvesting vibration. In this article, experimental tests on a circular plate, to evaluate the electric produced by at low acceleration over wide range of ambient vibration frequency, are presented. The analysis presented and discussed. results demonstrate potentiality using low...

The accurate simulation of excitonic energy transfer in molecular complexes with coupled electronic and vibrational degrees of freedom is essential for comparing excitonic system parameters obtained from ab initio methods with measured time-resolved spectra. Several exact methods for computing the exciton dynamics within a density-matrix formalism are known but are restricted to small systems w...

Energy harvesting has been around for more than a decade, with continual research tackling the issues of charging and powering up electronic gadgets. Because its multiple advantages, such as greater mobility longer lifespan, notion energy acquired broad popularity. Researchers are investigating methods to harness created by vibrations from various materials transducers part conservation movemen...

Stochastic resonance has seen wide application in the physical sciences as a tool to understand weak signal amplification by noise. However, this apparently counterintuitive phenomenon does not appear to have been exploited as a tool to enhance vibrational energy harvesting. In this note we demonstrate that by adding periodic forcing to a vibrationally excited energy harvesting mechanism, the p...

Energy harvesting is an emerging technology with applications to handheld, portable, and implantable electronics. Harvesting ambient vibration energy through piezoelectric (PE) means is a popular energy-harvesting technique that can potentially supply 10’s-100’s of μW of available power [1]. One of the limitations of existing PE-harvesters is in their interface circuitry. Commonly used full-bri...
