“…By using a gear (Priya, 2005;Rastegar and Murray, 2009), the input frequency can be amplified according to the number of gear teeth. In the two-stage design, the low excitation frequency can be further amplified to the high natural frequency of the cantilever beam (Rastegar et al, 2006;Lee et al, 2007;Tieck et al, 2006;Wickenheiser and Garcia, 2010;Kulah and Najafi, 2008). Such techniques decouple the excitation frequency and the vibration frequency of an energy harvester (i.e., its resonance frequency).…”

“…Actually, in the piezoelectric windmill design, another frequency up-conversion mechanism was included, which was presented as the concept of two-stage energy harvesting design by Rastegar et al (2006) or similarly termed as a "mechanical rectification approach" by Tieck et al (2006). The basic operation of such a two-stage energy harvester is shown in Figure 38.…”

The dramatic reduction in power consumption of current integrated circuits has evoked great research interests in harvesting ambient energy, such as vibrations, as a potential power supply for electronic devices to avoid battery replacement. Currently, most vibration-based energy harvesters are designed as linear resonators to achieve optimal performance by matching their resonance frequencies with the ambient excitation frequencies a priori. However, a slight shift of the excitation frequency will cause a dramatic reduction in performance. Unfortunately, in the vast majority of practical cases, the ambient vibrations are frequency-varying or totally random with energy distributed over a wide frequency spectrum. Hence, developing techniques to increase the bandwidth of vibration-based energy harvesters has become the next important problem in energy harvesting. This paper reviews the advances made in the past few years on this issue. The broadband vibration-based energy harvesting solutions, covering resonance tuning, 2 multimodal energy harvesting, frequency up-conversion and techniques exploiting nonlinear oscillations, are summarized in detail with regard to their merits and applicability in different circumstances.

“…The third approach may be termed frequency conversion. In the device proposed by Rastegar et al [69] , a low frequency oscillator is tuned to ambient vibrations but this is coupled into a high frequency resonant structure which performs the conversion to electrical energy. Experimental results for this proposed method are not presented but it is apparent that ensuring efficient coupling between low and high frequency oscillators is critical to the efficiency of the overall structure.…”

Wireless sensor networks (WSNs) offer an attractive solution to many environmental, security, and process monitoring problems. However, one barrier to their fuller adoption is the need to supply electrical power over extended periods of time without the need for dedicated wiring. Energy harvesting provides a potential solution to this problem in many applications. This paper reviews the characteristics and energy requirements of typical sensor network nodes, assesses a range of potential ambient energy sources, and outlines the characteristics of a wide range of energy conversion devices. It then proposes a method to compare these diverse sources and conversion mechanisms in terms of their normalised power density.

“…Impact driven devices as in [20,21,22,23] bear the risk of damaging the brittle piezoelectric ceramic material in the long term. A more promising approach appears to be plucking via plectra [24,25,26]. The contact-less magnetic coupling chosen by the authors has also been employed by others [27].…”

Human motion energy harvesting as an alternative to battery powering in body worn and implanted devices is challenging during prolonged periods of inactivity. Even a buffer energy storage system will run out of power eventually if there is no external acceleration to the harvester. This paper presents a method to actuate the rotor inside a previously presented rotational piezoelectric energy harvester wirelessly via a magnetic reluctance coupling to an external driving rotor with one or more permanent magnet stacks attached. *Manuscript(includes changes marked in red font for revision documents) Click here to view linked References of the orientation of the device with respect to gravity, which is desirable for real world applications. Lateral misalignment between the harvester and the driving magnet can also be overcome. The largest distance of power transfer reached was 32 mm with the largest magnets tested, and the optimal power output into a resistive load was over 100 µW at a frequency of 25 Hz.The functional volume of the harvester is 1.85 cm 3 -similar to the size of a wristwatch.
