In this study, we developed a conceptual design for a high resolution multichannel ECG data acquisition system for recording of electrical activity of the heart. The system has modular architecture, both in hardware and software layers. It consists of several recording units controlled by sub-microcontrollers, and one main unit that contains the main-microcontroller. Special distributed message based operating system has been developed and embedded to sub-microcontrollers and main-microcontroller to provide communication between them. The operating system is accomplished by the General Purpose Parallel Bus (GPPB) developed for this design. GPPB is responsible to convey commands, data, addresses, and handshaking messages. In each recording unit, 8 channels have been sampled by octal simultaneous 24-bit high resolution ∑-∆ analog-to-digital converter. Sampled data is read out via Serial Peripheral Interface (SPI) by the corresponding sub-microcontroller. Then, data in the sub-microcontrollers are transferred to the main-microcontroller using GPPB. At the last step, recorded data is sent from the main-microcontroller to the computer using USB interface.

Design and Optimization of Nanoantennas for Nano-Optical Applications Işıklar, Göktuğ; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2020-9) In this study, design and simulation of plasmonic nanoantenna structures to obtain high power enhancement capabilities at optical frequencies, as well as utilization of nanoantennas for imaging and sensing applications are presented. Plasmonic characteristics of nanoantennas, which depend on many parameters, such as material, frequency, geometry, and size, are investigated in detail via computational analyses of various nanoantenna structures. Numerical solutions of electromagnetic problems are performe...
Design and implementation of labview based data acquisition and image reconstruction environment for Metu-mrı system Özsüt, Murat Eşref; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2005) Data acquisition and image reconstruction tasks of METU Magnetic Resonance Imaging (MRI) System are used to be performed by a 15 year-old technology. This system is incapable of transmitting control signals simultaneously and has memory limitations. Control software is written mostly in assembly language, which is hard to modify, with very limited user interface functionality, and time consuming. In order to improve the system, a LabVIEW based data acquisition system consisting of a NI-6713 D/A card (to gen...
Design of a dual polarized low profile antenna for microwave brain imaging Üçel, Kaan; Alatan, Lale; Department of Electrical and Electronics Engineering (2022-5-9) In this thesis, a low profile, low cost, wide band (0.9-2GHz) dual linearly polarized printed dipole antenna is designed to be used in microwave brain imaging systems. Dual polarization feature offers superior data acquisition through polarization diversity for better image quality. Starting from a simple printed dipole, antenna structure is modified step by step to meet these design requirements. Since a conductive surface in close vicinity of the antenna affects antenna performance, in order to obtain uni...
Development of a resonant mass sensor for MEMS based cell detection applications Eroğlu, Deniz; Külah, Haluk; Department of Electrical and Electronics Engineering (2012) This thesis reports design and implementation of a MEMS based resonant mass sensor for cell detection applications. The main objective of the thesis is the real-time detection of captured cells inside liquid medium and obtaining the detection results by electronic means, without the aid of any external optical instruments. A new resonant mass sensor architecture is presented that has various advantages over its conventional counterparts. The device oscillates in the lateral direction, eliminating squeeze fi...
Theoretical and experimental investigation of fluid rheology effects on modulated ultrasound propagation Ozkok, Okan; Uludağ, Yusuf (2014-09-01) A mathematical model is developed and presented to capture the effect of viscoelastic nature of a material on modulated ultrasound (US) pulses. The model is established by considering perturbation of material elements subject to modulated US pulses and by introducing the exponential relaxation of the perturbed fluid elements with a spectrum of time constants. Both the model and experimental findings revealed that consecutive perturbation of a material via the modulated US pulses enabled to probe the relaxat...
