Recently, energy scavenging studies have become an important research area not only for the utilization of ambient energy sources but also for their high potential to replace the batteries especially for wireless body area networks (WBANs). Conventionally, batteries are used to provide energy to the WBANs. Amount of energy provided by batteries limits on-board features and communication range of the WBANs. Also, battery recharging or replacement is significantly impractical. Therefore, different energy scavenging interface circuits with different efficiencies have been proposed to overcome these limitations. This study focuses on energy scavengers and their potential utilization for low-power systems. Particularly, energy scavenging interface circuits for the WBANs are investigated in this paper.


Energy scavenging from low-frequency vibrations by using frequency up-conversion for wireless sensor applications
Külah, Haluk (2008-03-01)
This paper presents an electromagnetic (EM) vibration-to-electrical power generator for wireless sensors, which can scavenge energy from low-frequency external vibrations. For most wireless applications, the ambient vibration is generally at very low frequencies (1-100 Hz), and traditional scavenging techniques cannot generate enough energy for proper operation. The reported generator up-converts low-frequency environmental vibrations to a higher frequency through a mechanical frequency up-converter using a...

Energy harvesting from piezoelectric stacks via impacting beam
Özpak, Yiğit; Çalışkan, Mehmet; Department of Mechanical Engineering (2014)
Piezoelectric materials can be used for energy harvesting from ambient vibration due to their high power density and ease of application. Two basic methods, namely, tuning the natural frequency to the operational frequency and increasing the operation bandwidth of the harvester are commonly employed to maximize the energy harvested from piezoelectric materials. Majority of the studies performed in recent years focus mostly on tuning the natural frequency of the harvester. However, small deviations in operat...

Chamanian, Salar; Baghaee, Sajjad; Ulusan, Hasan; Zorlu, Ozge; Külah, Haluk; Uysal, Elif (2014-10-01)
This paper presents a wireless sensor node (WSN) system where an electromagnetic (EM) energy harvester is utilized for charging its rechargeable batteries while the system is operational. The capability and the performance of an in-house low-frequency EM energy harvester for charging rechargeable NiMH batteries were experimentally verified in comparison to a regular battery charger. Furthermore, the power consumption of MicaZ motes, used as the WSN, was evaluated in detail for different operation conditions...
