“…1 shows the energy harvesting powered node that consists of an energy harvester, an optional rectifier for AC input, a power management circuit (PMC), an energy storage device, an energy-aware interface (EAI), and a wireless sensor node [9], [10]. The rectifier converts AC voltage from a M8528-P2 macro-fiber composite (MFC) [18], which is bonded on a carbon fiber composite as the vibration energy harvester (VEH) into DC. The airflow energy harvester (AEH) consists of a turbine and a DC generator [4], which does not require rectification.…”
