This paper presents an electromagnetic (EM) vibrationto-electrical power generator which can efficiently scavenge energy from low-frequency external vibrations. The reported generator up-converts low-frequency environmental vibrations to a much higher frequency through a novel electro-mechanical frequency up-converter using a magnet, and hence provides efficient energy conversion even at low frequencies. Power is generated by means of electromagnetic induction using a magnet and coils on top of resonating cantilever beams. The expected maximum power from a single cantilever is 2.5muW in vacuum. The proposed system has been tested in milliscale and the frequency up-conversion technique has been verified.

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...
An Electromagnetic Micro Power Generator for Low-Frequency Environmental Vibrations Based on the Frequency Upconversion Technique
Sari, Ibrahim; Balkan, Raif Tuna; Külah, Haluk (2010-02-01)
This paper presents a microelectromechanical-system-based electromagnetic vibration-to-electrical power generator that can harvest energy from low-frequency external vibrations. The efficiency of vibration-based harvesters is proportional to excitation frequency, so the proposed generator is designed to convert low-frequency environmental vibrations to a higher frequency by employing the frequency upconversion (FupC) technique. It has been shown that the generator can effectively harvest energy from environ...
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 harvesting system for low frequency applications with a passive interface ASIC in standard CMOS
Rahimi, Arian; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-01)
This paper presents a compact energy harvesting system, which consists of an electromagnetic (EM) generator converting ambient low frequency vibrations to DC voltage by using a highly efficient full-wave rectifier in a System-on-Package (Sop). Frequency Up-Conversion technique has been utilized by the in-house EM transducer to harvest energy from very low frequency vibrations (<5 Hz). The interface ASIC is a passive rectifier based on the boot-strap rectification (BSR) technique to decrease the effective th...
A wideband electromagnetic micro power generator for wireless microsystems
Sari, Ibrahim; Balkan, Tuna; Külah, Haluk (2007-06-14)
This paper presents a wideband electromagnetic (EM) vibration-to-electrical power generator which can efficiently scavenge energy and generate steady power over a predetermined frequency range. Power is generated by means of electromagnetic induction using a magnet and coils on top of resonating cantilever beams. The reported generator covers a wide band of external vibration frequency by implementing a number of serially connected cantilevers in different lengths. The device generates 0.5 mu W continuous p...
