Webinar on energy harvesting took place on Wednesday (25.11.2020) of the Polish time. Our speaker was Martin Siewe from University of Yaounde, Cameroon who presented a lecture: “Nonlinear characterization of some wireless energy harvesters”
Abstract: This paper examines the oscillations of a spherical pendulum with horizontal Lissajous excitation. The pendulum has two degrees of freedom: a rotational angle defined in the horizontal plane and an inclination angle defined by the pendulum with respect to the vertical z axis. The results of numerical simulations are illustrated with the mathematical model...
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...
