(Nanowerk Spotlight) All mechanical systems exhibit vibrational resonances, where energy transmission through the structure spikes at certain natural frequencies. This resonance effect stems from the ...

Researchers at the University of Miyazaki in Japan used a new non-destructive method to enable them to investigate solar cell vibrations independently of module components. The study included ...

Energy harvesting technology is applied to "harvest" electrical energy from dumped energy sources around us, such as vibration, heat, light, and so on. A device that is capable of harvesting energy ...

There are natural frequencies in all equipment that have components. Generally, they exist in the 8 to 200 Hz environmental spectrum. Figure 46.1 demonstrates the transmissibility and resonant ...
