摘要: Recent progresses in both microelectronic and energy conversion fields have made the conception of truly self-powered, wireless systems no longer chimerical. Combined with increasing demands from industries for left-behind sensors sensor networks, such advances therefore led to an imminent technological breakthrough terms autonomous devices. Whereas some are commercially available, optimization microgenerators that harvest their near environment is still issue giving a positive balance electronic circuits feature complex functions, or minimizing amount needed active material. Many sources available harvesting (thermal, solar, so on), but vibrations one most commonly present significant amount. For source, piezoelectric elements very good agents conversion, as they relatively high coupling coefficient well power densities. Several ways can be explored, two main issues concern increase converted extracted energies, independency harvested load connected harvester.
