This paper presents a novel method and apparatus for converting keystrokes to electrical energy using a resonant energy harvester, which can be coupled with keyboards. The state-of-the-art dome switch design is modified to excite the tip of the energy harvester beam. Piezoelectric transduction converts vibrations to electrical power. The energy harvester design is optimized to give highest voltage output under use conditions, and is fabricated. A close match is observed for the first natural frequency. When the piezoelectric energy harvester is excited at 7.62 Hz with tip excitation to emulate keyboard use, 16.95 mu W of power is generated.

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...
An adaptive piezoelectric energy harvesting interface circuit with a novel peak detector
Chamanian, S.; Zorlu, O.; Külah, Haluk; Muhtaroglu, A. (2015-03-26)
This paper presents a fully self-powered interface circuit with a novel peak detector for piezoelectric energy harvesters (PEH). This circuit can be utilized to scavenge energy from low power environmental vibrations in 10s of mu W range. Synchronous switching technique is used to extract maximum available power where switching instants are detected independently from excitation changes of the PEH. The proposed peak detector senses voltages higher than power supply for a wide frequency range of input vibrat...
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 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...
