This paper presents a miniature and non-resonant vibration based electromagnetic (EM) energy harvester, which generates energy from low frequency and low amplitude vibrations. The structure combines a MEMS-based coil realized on a parylene cantilever, and a miniature NdFeB magnet, resulting in a small sized EM harvester prototype with a strong magnetic part. The magnet is attached to a moving platform, whereas the coil is fixed to a stationary base. The mechanical frequency up-conversion (mFupC) technique is utilized to increase the energy conversion efficiency. The fabricated prototype has a volume of 120 mm(3) and generates 1.44 mV RMS voltage and 24 nW RMS power from 10 Hz, 4 mm peak-to-peak (0.8 g) external vibrations. A power density of 200 nW/cm(3) has been realized with the prototype.

A MEMS-based energy harvester for generating energy from non-resonant environmental vibrations
Zorlu, Ozge; Külah, Haluk (2013-11-01)
This paper presents a non-resonant vibration based electromagnetic MEMS energy harvester, which generates energy from low frequency vibrations with low displacement amplitude. The harvester is composed of an energy harvester chip, housing two electroplated copper micro coils realized on parylene cantilevers and a miniature NdFeB magnet with two mechanical barrier arms. The structure uses the mechanical frequency up conversion (mFupC) principle for energy generation. The non-resonant operation is maintained ...
An Electromagnetic Micro-Power Generator for Low Frequency Vibrations with Tunable Resonance
Türkyılmaz, Serhan; Muhtaroglu, A.; Külah, Haluk (2011-09-07)
This paper presents an electromagnetic (EM) micro-power generator with tunable resonance frequency which can harvest energy from low frequency environmental vibrations. The reported power generator up-converts low frequency environmental vibrations before mechanical-to-electrical energy conversion by utilizing two diaphragms with different resonance frequencies. Power is generated through electromagnetic induction by a magnet attached to the low frequency diaphragm, and a 50 turn, 2.1 Omega coil, and a magn...
A Mechanical Frequency Up-Conversion Mechanism for Vibration Based Energy Harvesters
Zorlu, Ozge; Topal, Emre Tan; Külah, Haluk (2009-10-28)
This paper presents a new mechanical frequency up-conversion (FUC) mechanism for harvesting energy from external low frequency vibrations. The structure consists of a magnet placed on a support, a polystyrene cantilever carrying a pick-up coil, and a mechanical barrier which converts low frequency vibrations to a higher frequency, hence increasing the efficiency of the system. The tested structure proved to give 20.3 mV and 68.7 mu W RMS power output by up-converting 10 Hertz external vibration to 643 Hertz...
AN ELECTROMAGNETIC ENERGY HARVESTER FOR LOW FREQUENCY AND LOW-G VIBRATIONS WITH A MODIFIED FREQUENCY UP CONVERSION METHOD
Zorlu, Ozge; Turkyilmaz, Serol; Muhtaroglu, Ali; Külah, Haluk (2013-01-24)
This paper presents a MEMS-based electromagnetic (EM) energy harvester for low frequency and low acceleration vibrations. The harvester is an improved version of [1], which operates with the frequency up conversion (FupC) principle. The former structure was composed of a low-frequency diaphragm carrying a magnet and 16 high-frequency cantilevers with coils. In this work, the phase difference between the coil outputs, leading to voltage cancellation in serial connection, has been eliminated by using a single...
A Vibration-Based Electromagnetic Energy Harvester Using Mechanical Frequency Up-Conversion Method
Zorlu, Ozge; Topal, Emre Tan; Külah, Haluk (2011-02-01)
This paper presents a new vibration-based electromagnetic energy harvester using a mechanical frequency up-conversion method for harvesting energy from external low-frequency vibrations within a range of 1-10 Hz. The structure consists of a magnet placed on a diaphragm, a polystyrene cantilever carrying a pick-up coil, and a mechanical barrier which converts low-frequency vibrations to a higher frequency, hence increasing the efficiency of the system. The tested structure proved to generate 88.6 mV and 544....
