Vibration based electromagnetic energy harvesters (VEMEHs) for powering wireless sensor nodes (WSNs) and low power devices has got enormous research interests as alternative source of power. One of the prime limitations to the application of these harvesters as a replacement to battery systems is their dependency on the limited range of operating frequencies. This paper highlights the current advancements in the area of wide-band VEMEHs. All such VEMEHs have been studied and reported based on their range of operating frequencies, frequency bandwidth, overall volume, output voltage, the value of available output power, power density and the level of vibrations these harvesters are subjected to. Moreover the reported VEMEHs are categorized on the basis of their operating mechanism i.e eit... view more»
