Energy Asymmetry

We examine the influence of potential energy asymmetry on the power generated by energy harvesting system. We present results for the system consisting of two masses (magnets) attached to piezoelastic oscillators which vibrate in the magnetic field produced by the magnets attached directly to the harvesting device. The nonlinearity of the system is achieved by the variable strength of the magnetic fields produced by the static magnets. We additionally examine the influence of disproportion between piezoelastic beams stiffness, which is described by the mistuning parameter.

Magneto Rheological

Magneto Rheological Elastomers (MREs) are composite materials based on an elastomer filled by magnetic particles. Anisotropic MRE can be easily manufactured by curing the material under homogeneous magnetic field which creates column of particles. The magnetic and elastic properties are actually coupled making these MREs suitable for energy conversion. From these remarkable properties, an energy harvesting device is considered through the application of a DC bias magnetic induction on two MREs as a metal piece is applying an AC shear strain on them. Such strain therefore changes the permeabilities of the elastomers, hence generating an AC magnetic induction which can be converted into AC electrical signal with the help of a coil. The device is simulated with a Finite Element Method software to examine the effect of the MRE parameters, the DC bias magnetic induction and applied shear strain (amplitude and frequency) on the resulting electrical signal.
