This paper reports a compact magnetic transducer developed for generating electrical power from respiration. The device incorporates a side-drive turbine rotor with embedded permanent magnets and two stators, integrated into a poly(methyl methacrylate) (PMMA) package for actuation. The novelty and advantage of the design lies in almost full use of the available turbine volume together with two stators for both mechanical and electrical transduction, which leads to high rotational speeds and high voltage generation at low flow rates. A variety of turbine and stator designs were developed. In the best-performing design, the turbine reached 10 krpm rotational speed at 16 lpm flow rate and 74 mbar pressure drop. The open circuit voltage and output electrical power at this speed were measured to be 2.75 V and 0.06 mW on a matched resistive load, respectively. When operated at 10 krpm for 30 s, the device was able to store 1.28 mJ on a 1 mF capacitor. Tests at higher flow rates showed that the turbine can reach 30 krpm, leading to 8.14 V at the stator terminals and 0.51 mW output power. The results demonstrate the feasibility of this device to generate power from respiration, and its potential to be used in portable electronic devices.

An Adaptable Interface Circuit With Multistage Energy Extraction for Low-Power Piezoelectric Energy Harvesting MEMS Chamanian, Salar; Ulusan, Hasan; Koyuncuoglu, Aziz; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2019-03-01) This paper presents a self-powered interface circuit to extract energy from ambient vibrations for powering up microelectronic devices. The circuit interfaces a piezoelectric energy harvesting micro electro-mechanical systems (MEMS) device to scavenge acoustic energy. Synchronous electric charge extraction (SECE) technique is deployed through the implementation of a novel multistage energy extraction (MSEE) circuit in 180 nm HV CMOS technology to harvest and store energy.

A Compact Angular Rate Sensor System Using a Fully Decoupled Silicon-on-Glass MEMS Gyroscope Alper, Said Emre; Temiz, Yuksel; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2008-12-01) This paper presents the development of a compact single-axis angular rate sensor system employing a 100-mu m-thick single-crystal silicon microelectromechanical systems gyroscope with an improved decoupling arrangement between the drive and sense modes. The improved decoupling arrangement of the gyroscope enhances the robustness of sensing frame against drive-mode oscillations and therefore minimizes mechanical crosstalk between the drive and sense modes, yielding a small bias instability. The gyroscope cor...
A Self-Adapting Synchronized-Switch Interface Circuit for Piezoelectric Energy Harvesters Chamanian, Salar; Muhtaroglu, Ali; Külah, Haluk (Institute of Electrical and Electronics Engineers (IEEE), 2020-01-01) This paper presents a self-adapting synchronized-switch harvesting (SA-SSH) interface circuit to extract energy from vibration-based piezoelectric energy harvesters (PEHs). The implemented circuit utilizes a novel switching technique to recycle optimum amount of harvested charge on piezoelectric capacitance to strengthen the damping force, and simultaneously achieve load-independent energy extraction with a single inductor. Charge recycling is realized by adjusting extraction time, and optimized through a m...
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 Automatically Mode-Matched MEMS Gyroscope With Wide and Tunable Bandwidth Sonmezoglu, Soner; Alper, Said Emre; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2014-04-01) This paper presents the architecture and experimental verification of the automatic mode-matching system that uses the phase relationship between the residual quadrature and drive signals in a gyroscope to achieve and maintain matched resonance mode frequencies. The system also allows adjusting the system bandwidth with the aid of the proportional-integral controller parameters of the sense-mode force-feedback controller, independently from the mechanical sensor bandwidth. This paper experimentally examines...
