In this study, the fabrication of microfluidic devices for dielectrophoretic and acoustophoretic based applications with high-precision CNC machining has been presented. For both devices, molds out of stainless steel have been fabricated, and polymer molding is implemented. For dielectrophoretic device, the metal electrodes have been fabricated using high-precision machining and embedded into the device during the molding process. For acoustophoretic device, piezoelectric slides have been embedded into the device during the molding process. This is a pioneer study for the fabrication of microfluidic devices with embedded 3D electrodes and PZT slides

Design and implementation of A MEMS based gravimetric detector for cytometry applications
Bayraktar, Ekrem; Bayraktar, Ekrem; Department of Electrical and Electronics Engineering (2010)
This thesis reports design and implementation of a MEMS based gravimetric resonator for cytometry applications. There are mainly two objectives of this thesis; to enable in-flow analysis and to perform closed loop operation that does not require any additional processing or equipment. A novel MEMS based resonator with in-flow capabilities is proposed for detection of agents inside micro channels. High resolution of mass detection inside micro channels is planned to be succeeded with lateral motion in the mi...
Design of a high precision hybrid AM machine
Yılmaz, Yunus Emre; Dölen, Melik; Department of Mechanical Engineering (2019)
Precision requirements in fused deposition modelling (FDM) processes have been increasing in recent years, especially after recognizing the potential of FDM process to produce complex and functional components. In order to increase precision of FDM process, 6-axis hybrid manufacturing system, which can carry out additive- and subtractive manufacturing processes in one manufacturing system platform, is designed. During design, kinematic analysis of the machine is done, axial- and angular errors are estimated...
Constant voltage, constant frequency operation of a self-excited induction generator
Çalışkan, Ahmet; Üçtuğ, Yıldırım; Department of Electrical and Electronics Engineering (2005)
In this thesis, control schemes for the self-excited induction generator are developed with Matlab/Simulink. Self-excited induction generator is considered as a constant voltage-constant frequency supply for an isolated load. A wind turbine is assumed to be the variable-speed drive of the induction generator. Control schemes aim to ensure a constant voltage-constant frequency operation of the induction generator in case of the variations in the wind speed and/or the load. From the general model of the self-...
Comparison of Inverter Topologies Suited for Integrated Modular Motor Drive Applications
Ugur, Mesut; Sarac, Hakan; Keysan, Ozan (2018-08-30)
In this paper, various inverter topologies are compared for integrated modular motor drive (IMMD) applications. Two-level voltage source inverter (2L-VSI), three level voltage source inverter (3L-VSI) and series/parallel combinations of these topologies with system level modularity are compared in terms of voltage and current harmonic spectrum, passive component sizes and motor drive efficiency. New generation wide band-gap GaN power semiconductor devices are utilized in modular topologies and they are comp...
Design, fabrication, and characterization of micro thermal actuators
Gülcüler, Buğrahan; Azgın, Kıvanç; Department of Mechanical Engineering (2020-11)
This thesis presents the design, fabrication, and characterization of V-Type thermal actuators, which will be used in an actuator system that is planned to be a tensile and compressive test setup to characterize the expandible cells by the help of double- ended tuning fork resonators as a force sensing mechanism. Actuators are serially packed to increase the generated force by them while maintaining the same deflection values. They have been connected to the overall system by springs to create a force on te...
