AN ELECTROMAGNETIC MICRO POWER GENERATOR FOR LOW FREQUENCY ENVIRONMENTAL VIBRATIONS BASED ON THE FREQUENCY UP-CONVERSION TECHNIQUE Sari, Ibrahim; Balkan, Tuna; Külah, Haluk (2009-01-29) This paper presents an electromagnetic (EM) vibration-to-electrical power generator, which can efficiently harvest energy from low-frequency external vibrations by using frequency up-conversion. The generator can effectively scavenge energy from low frequency environmental vibrations of 70-150 Hz and generates 0.57 mV voltage with 0.25 nW power from a single cantilever at a vibration frequency of 95 Hz. The fabricated generator size is 8.5 x 7 x 2.5 mm(3) and a total number of 20 serially connected cantilev...
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...
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...
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 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...
