A linear non-resonant kinetic energy harvester for implantable devices is presented. The design contains a metal platform with permanent magnets, two stators with three-dimensional helical coils for increased power generation, ball bearings, and a polydimethylsiloxane (PDMS) package for biocompatibility. Mechanical excitation of this device within the body due to daily activities leads to a relative motion between the platform and stators, resulting in electromagnetic induction. Initial prototypes without packaging have been fabricated and characterized on a linear shaker. Dynamic tests showed that the friction force acting on the platform is on the order of 0.6 mN. The resistance and the inductance of the coils were measured to be 2.2 and 0.4 mu H, respectively. A peak open circuit voltage of 1.05 mV was generated per stator at a platform speed of 5.8 cm/s. Further development of this device offers potential for recharging the batteries of implantable biomedical devices within the body.

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 ...
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...
An efficient integrated interface electronics for electromagnetic energy harvesting from low voltage sources Ulusan, Hasan; Gharehbaghi, Kaveh; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2013-12-01) This paper presents a fully-integrated self-powered interface circuit for efficient rectification of the signals generated by vibration based low-voltage electromagnetic (EM) energy harvesters. The circuit utilizes an improved AC/DC doubler structure with active diodes to minimize the forward bias voltage drop for enhancing the rectifier efficiency. The comparators in the active diodes are powered internally by another passive AC/DC doubler with diode connected transistors. The performance is maximized thro...
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...
A Fully Integrated Power Management Circuit for Electromagnetic Energy Harvesting Applications Gharehbaghi, Kaveh; Ulusan, Hasan; Zorlu, Ozge; Muhtaroglu, Ali; Külah, Haluk (2012-12-05) In this paper a 90 nm power management circuit for vibration based electromagnetic energy harvesters is introduced to generate 1 V from the rectified DC voltage. A mode selector block is designed to detect the output DC voltage level of the rectifier and adjust the mode of the driver block. In order to set the output to the desired level, a regulation system with negative feedback topology is utilized. The circuit is able to operate with input voltages as low as 0.25 V. The simulation results also show that...
