Book Synopsis Springless Electromagnetic Vibration Energy Harvesters by : Mohamed Bendame
Download or read book Springless Electromagnetic Vibration Energy Harvesters written by Mohamed Bendame and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The abundance of environmental kinetic energy combined with advances in the electronics and MEMS industries have opened a window of opportunities for the design and fabrication of self-powered, battery independent, low-power electronic devices. Kinetic energy harvesting, the process that captures vibrations from the environment or surrounding systems and converts them into electrical power, o ers the prospects of unlimited power for such systems. Vibration energy harvesters (VEHs) are vibration-based micro-power generators that utilize mechanical oscillators to capture ambient vibration energy and convert it into electrical power using one of three main transduction mechanisms, electromagnetic, electrostatic, or piezoelectric. A key feature of VEHs is their ability to harvest maximum environmental vibration energy from low amplitude and low frequency vibrations from a wide spectrum of frequencies. Traditional VEHs use linear mechanical oscillators as their harvesting element and are tuned to harvest environmental vibrations at resonance frequency present within the application environment. These VEHs are usually designed to harvest energy from high frequency vibrations in a narrow band in the vicinity of the natural frequency of the mechanical oscillator, and outside this narrow band of frequencies their output power is signi cantly reduced. In environments where ambient vibrations are random and only available at low frequencies, conventional harvesters prove to be ine ective. Although such devices are capable of generating power from vibrations with frequencies close to their resonance frequency, the need for harvesters that can harvest energy from broadband vibration sources has become an interesting research topic in recent years. To overcome the limitations associated with traditional vibration energy harvesters, nonlinear phenomena, such as hardening and softening nonlinearities, magnetic levitation, and pact have been sought as a solution to broadband vibration energy harvesting. In this thesis we aim to address this challenge by investigating a new architecture of an electromagnetic vibration energy harvester, the electromagnetic \Springless" vibration energy harvester (SVEH). The new architecture di ers from traditional harvester as it uses a double-impact oscillator as its harvesting element as opposed to the linear model. Experimental results show that the new SVEH is capable of harvesting vibration energies with frequencies as low as 5Hz and amplitudes as low as 0.05 g in a frequency band of about 8Hz. The harvester generates maximum output power of 12 mWatt from vibrations with amplitude of 0.5 g and an optimal load of 3.6 ohms. Experimental results also show that the "nonlinear" center frequency of the harvester is not constant, as in the case of conventional harvesters, but depends on the amplitude and frequency of the external vibrations and whether the harvester is operated in the vertical or horizontal position. Experimental as well as the numerical frequency response curves of the SVEH also show the existence of hardening nonlinearity in the horizontal con guration and softening nonlinearity in the vertical con guration in the system. The hardening e ect allows harvesting of energy in the high frequency spectrum, about 25 Hz and a bandwidth of 7 Hz, while the softening e ect allows harvesting at the lower end of the frequency spectrum, which is around 5 Hz and a bandwidth of 8 Hz. Models of the SVEH in the vertical and horizontal con gurations were developed and nonlinear numerical and analytical methods were used to analyze the system to gain a deeper understanding of the system's behavior. The experimental data is then used to validate the models. The harvester's ability to harvest vibration energy from low frequency ( 25Hz) and low amplitude vibrations ( 0:5g) in a wide band ( 5Hz) is one of the unique features of the SVEH demonstrated in this work.

Book Synopsis Study of Electromagnetic Vibration Energy Harvesting with Free/impact Motion for Low Frequency Operation by :
Download or read book Study of Electromagnetic Vibration Energy Harvesting with Free/impact Motion for Low Frequency Operation written by and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This paper presents study of an electromagnetic vibration energy harvesting configuration that can work effectively at low frequencies. Unlike the conventional form of vibration energy harvesters in which the mass is directly connected to a vibrating frame with spring suspension, in the proposed configuration a permanent magnet mass is allowed to move freely within a certain distance inside a frame-carrying coil and make impacts with spring end stops. The free motion distance allows matching lower vibration frequencies with an increase in the relative amplitude at resonance. Hence, significant power could be generated at low frequencies. A nonlinear mathematical model including impact and electromagnetic induction is derived. Study of the dynamic behaviour and investigation of the system performance is carried out with the aid of case study simulation. The proposed harvester shows a unique dynamic behaviour in which different ways of response of the internal relative oscillation appear over the range of input frequencies. A mathematical condition for the response type at which the higher relative amplitude appears is derived, followed by an investigation of the system resonant frequency and relative amplitude. The resonant frequency shows a dependency on the free motion distance as well as the utilized mass and spring stiffness. Simulation and experimental comparisons are carried out between the proposed harvester and similar conventional one tuned at the same input frequency. The power generated by the proposed harvesting configuration can reach more than 12 times at 11 Hz in the simulation case and about 10 times at 10 Hz in the experimental case. Simulation comparison also shows that this power magnification increases by matching lower frequencies which emphasize the advantages of the proposed configuration for low frequency operation. Highlights: We present an electromagnetic vibration energy harvester based on free/impact motion. The proposed harvester has a resonant behaviour. However, it shows a unique way of oscillation. Its resonant frequency can be shifted to lower range with an increase in the resonant relative amplitude Simulation and experimental comparison between the proposed harvester and similar conventional one shows its advantages at low frequencies.
Book Synopsis Energy Scavenging for Wireless Sensor Networks by : Shad Roundy
Download or read book Energy Scavenging for Wireless Sensor Networks written by Shad Roundy and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast reduction in size and power consumption of CMOS circuitry has led to a large research effort based around the vision of wireless sensor networks. The proposed networks will be comprised of thousands of small wireless nodes that operate in a multi-hop fashion, replacing long transmission distances with many low power, low cost wireless devices. The result will be the creation of an intelligent environment responding to its inhabitants and ambient conditions. Wireless devices currently being designed and built for use in such environments typically run on batteries. However, as the networks increase in number and the devices decrease in size, the replacement of depleted batteries will not be practical. The cost of replacing batteries in a few devices that make up a small network about once per year is modest. However, the cost of replacing thousands of devices in a single building annually, some of which are in areas difficult to access, is simply not practical. Another approach would be to use a battery that is large enough to last the entire lifetime of the wireless sensor device. However, a battery large enough to last the lifetime of the device would dominate the overall system size and cost, and thus is not very attractive. Alternative methods of powering the devices that will make up the wireless networks are desperately needed.
