How Can Energy be Scavenged from Wideband Vibrations?

Portable devices, including wireless multi-sensor nodes and wearable electronics, are becoming widely used. Such systems require continuous power sources, and sometimes the use of batteries can be a limiting factor in the exploitation of the device functionality, especially when application contexts require a long operation time. In the framework of autonomous systems, power harvesting represents an interesting and powerful solution to scavenge energy from the environment.
