Abstract: Based on the improved interval extension, a robust optimization method for nonlinear monostable energy harvesters with uncertainties is developed. In this method, the 2nd order terms in the interval extension formula of the objective function (output voltage) are kept so this approach is suitable for a nonlinear energy harvesting system. To illustrate this method,...
Abstract: Mechanical coupling in similar energy harvesters has the potential to enhance their broadband harvesting capability. However, often the performance of one harvester dominates the other, and the coupling transfers energy from the high frequency harvester to the low frequency harvester, thus reducing the capability of the high frequency harvester. Hence, researchers have proposed using...
Currently, an increasing research activity is observed in the field of distributed energy harvesting from ambient vibration. The result of these studies are complex systems using multi-field devices with piezoelectric, electrostatic, and electromagnetic transducers. High availability of vibration sources compensate relatively low efficiency. Linear transduces should be adjusted to the source frequencies in their resonance...
