Virtual symposium on “Nonlinear Energy Harvesting from Mechanical and Aeroelastic Vibrations” (ICNAAM2020)

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…

Virtual symposium on “Frequency Broadband Energy Harvesting From Nonlinear Vibrations” (NODYCON 2021)

Recently, energy harvesting from ambient vibration is an active area of research and facing various applications sufficient to power simple wireless and portable devices. Kinematically excited nonlinear resonators with piezoelectric, electrostatic, and electromagnetic transducers are proposed. Such complex devices are characterized with a frequency broad band effect. Other nonlinear effects as vibration synchronization, multiple solutions,…
