This paper presents an energy scavenging technique, merging microfluidics with electrostatic energy harvesting. The method employs droplet-based microflow of two phases with different electrical permittivities, resulting in a capacitance change across the microchannel, to harvest electrical energy. The technique is implemented on 3 mm wide, 1 mm deep minichannels. It is shown that 0.4 nW can be harvested using a single electrode pair, with air and water as the two phases flowing at 1 ml/min. The generated power can be increased significantly by microscale implementation, where the number of electrodes can also be increased for further improvement.

Optimization of AA-Battery Sized Electromagnetic Energy Harvesters: Reducing the Resonance Frequency Using a Non-Magnetic Inertial Mass Yasar, Oguz; Ulusan, Hasan; Zorlu, Ozge; Sardan-Sukas, Ozlem; Külah, Haluk (2018-06-01) This paper presents an optimization study for a miniature electromagnetic energy harvester, by incorporating a non-magnetic inertial mass (tungsten) along with the axially oriented moving magnets. The aim is to decrease the operation frequency and increase the output power of the harvester with the usage of higher density material and larger magnetic flux density. Dimensions of the magnets are optimized according to the harvester dimensions and magnetic flux gradients. Additionally, coil length, width, resi...
Hybrid energy harvester using piezoelectric and pyroelectric properties of PZT 5A ceramics Koyuncuoğlu, Aziz; Zorlu, Özge; Okutucu Özyurt, Hanife Tuba; Külah, Haluk (2013-07-15) This paper presents a novel hybrid piezoelectric-pyroelectric energy harvester using a cantilever beam with a PZT tip mass. The cantilever is moving between two surfaces with different temperatures under external vibration. PZT ceramic is used as the piezoelectric material, which also has pyroelectric characteristics. By using the pyroelectric effect along with the piezoelectric one, the output RMS voltage of the PZT ceramic was enhanced up to 10% under 50°C ΔT.
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...
Performance-Based Seismic Design of Bitlis River Viaduct Based on Damage Control Using Seismic Isolation and Energy Dissipation Devices Dicleli, Murat (2017-05-28) This paper presents a sample application of seismic isolation techniques in performance-based design of a major viaduct. The Bitlis River viaduct is located in a seismically active region. The targeted performance goal required no damage at 475-year return period earthquake and repairable damage at 2475-year return period earthquake. The bridge is designed with a seismic isolation system composed of spherical bearings and MRSD (Multidirectional Re-centering steel Damper) hysteretic dampers. The MRSD is a re...
Thermal loading and unloading of a solid cylinder subjected to periodic internal energy cycling Eraslan, Ahmet Nedim (2017-03-01) An analytical model is developed to estimate partially plastic loading and unloading behavior of a transient internal energy cycling solid cylinder. The cylinder is initially at zero temperature, but for times greater than zero, heat is generated or consumed internally at a time dependent rate. The transient temperature distribution in the cylinder is obtained by using Duhamel's theorem. As the cylinder is heated or cooled slowly the uncoupled theory of thermal stress is used. Under these circumstances elas...
