Typically two configurations are used for energy harvesting with different advantages: piezoelastic and piezomagnetoelastic. Best performance of the piezoelastic configuration is when the excitation frequency is close to the resonance frequency. If the input frequency slightly deviates from the natural frequency, the generated power is severely decreased. To tackle the problem, the piezomagneto...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

This article presents different micromechanical modelling techniques based on analytical and numerical approaches to determine the effective elastic piezoelectric (piezoelastic) properties of graphene-based composite materials. Different types, orientations shapes as well geometrical parameters fiber reinforcement are considered for estimating properties. The predicted with without considering ...

Flexible piezoelectric devices made of polymeric materials are widely used for microand nanoelectro-mechanical systems. In particular, numerous recent applications concern energy harvesting. Due to the importance of computational modeling to understand the influence that microscale geometry and constitutive variables exert on the macroscopic behavior, a numerical approach is developed here for ...

We present first observations of solar polarization with a new imaging polarimetry system that simultaneously records three Stokes components, I , Q, V or I , U , V , in a single CCD. This instrument is an intermediate version on the way to ZIMPOL II (Zürich Imaging Stokes Polarimeter II), which will record all four Stokes parameters (Stenflo et al. 1992). The principle of operation is based on...
