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 threshold voltage of the utilized diodes, attaining a high AC/DC conversion efficiency in a standard 0.35 mu m CMOS process. The energy harvesting system has been tested within a frequency range of 2-10 Hz. The autonomous system with a volume of 21 cm(3), delivers 128 mu W DC power to an 80 mu A load at an external vibration frequency of 2 Hz and 72 mg peak acceleration while a 1.6V DC voltage is generated. The maximum overall power density is measured as 6.1 mu W/cm(3). Furthermore, the reliable operation of a commercially available temperature sensor, as a realistic load, has also been demonstrated by using the energy harvester as a DC supply.

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 Self-Powered Rectifier Circuit for Low-Voltage Energy Harvesting Applications Ulusan, Hasan; Gharehbaghi, Kaveh; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-05) This paper presents a fully self-powered low voltage and low power active rectifier circuit for vibration-based electromagnetic (EM) energy harvesters. A passive AC/DC doubler is used to provide a supply voltage for the active rectifier circuit. The proposed circuit is designed using standard 90 nm TSMC CMOS technology. The simulation results show that the proposed active rectifier circuit has voltage conversion ratio higher than 150% when the input peak voltage is more than 100 mV at open-load condition. T...
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 ...
