Hybrid energy harvesting of piezoelectric and electromagnetic using vibration excitation of bimorph cantilever beam

Harvesting energy is the technique for accumulating energy from the surrounding environment and transforming it into electricity. Instead, the evolution of low power electronics, dependencies on battery as a power source that can decrease the lifespan and function capability. Thus, many researchers...
