Capacitive ECG (cECG), a technique older than 50, is able to replace the gold standard ECG only in certain applications where unobtrusiveness and conformity are aimed at the expense of reduced signal quality. Triboelectric surface charges, motion artifacts, and resulting time-variant coupling capacitances are among the reasons for the signal deformations in cECG. In this paper, the mechanical vibrations of the human body are proposed as the source of time-variant coupling capacitances causing motion artifacts, which questions the applicability of adaptive filtering approaches to the problem of time-variant coupling capacitance. Ballistocardiogram (BCG) measurements on cECG electrodes are recorded and analyzed to investigate how these mechanical vibrations reflect on a differential biopotential measurement. Furthermore, using measured signals in a human experiment, numerical and test bench simulations were conducted to replicate how triboelectric surface charges might cause deformation on cECG signals.

Fiber-integrated terahertz spectrometer driven by ultrafast ytterbium doped fiber laser Keskin, Hakan; Altan, Hakan; Berberoğlu, Halil Giray; Department of Physics (2013) In this thesis, development of a Terahertz time domain spectrometer (THz-TDS) driven by an ultrafast Ytterbium (Yb) doped ber laser, whose repetition rate can be tuned, was investigated to show that it can be used in Optical Sampling by Cavity Tuning (OSCAT) technique which enables the fast acquisition of THz pulse pro les. Central wavelength of the Yb-doped laser developed for this study is 1031 nm. The output average power was measured to be 90 mW which corresponds to about two nanojoule per pulse at 51 ...
Colloidal CdSe Quantum Wells with Graded Shell Composition for Low-Threshold Amplified Spontaneous Emission and Highly Efficient Electroluminescence Keleştemur, Yusuf; Anni, Marco; Yakunin, Sergii; De Giorgi, Maria Luisa; Kovalenko, Maksym V. (2019-12-01) Semiconductor nanoplatelets (NPLs) have emerged as a very promising class of colloidal nanocrystals for light-emitting devices owing to their quantum-well-like electronic and optical characteristics. However, their lower photoluminescence quantum yield (PLQY) and limited stability have hampered the realization of their outstanding luminescent properties in device applications. Here, to address these deficiencies, we present a two-step synthetic approach that enables the synthesis of core/shell NPLs with pre...
Microcontroller controlled, multifrequency electrical impedance tomograph Arpınar, VE; Eyüboğlu, Behçet Murat (2001-10-28) In this study, development of a microcontroller controlled multifrequency electrical impedance tomography system is aimed. In this system, current injection and voltage measurements are both performed by the surface electrodes, which are microcontroller controlled. Data acquisition system process the measured signal using continuous time quadrature demodulator. After that, it converts analog information to digital and transfers it to the PC.
Current injection optimization for magnetic resonance-electrical impedance tomography (MREIT) Altunel, H.; Eyüboğlu, Behçet Murat; KÖKSAL, ADNAN (2007-09-02) Determining optimum current injection pattern is of interest in magnetic resonance-electrical impedance tomography (MREIT), since it helps in detecting smaller inhomogeneities within the body when total injected current into the body is limited. Based on this fact, for 2-D cylindrical body with concentric and cylindrical inhomogeneity, current injection optimization problem is analytically formulated, based on distinguishability definition for MREIT. The exterior penalty method is used to solve the optimiza...
Magnetohydrodynamic flow imaging of ionic solutions using electrical current injection and MR phase measurements Eroglu, Hasan H.; Sadighi, Mehdi; Eyüboğlu, Behçet Murat (Elsevier BV, 2019-06-01) In this study, a method is proposed to image magnetohydrodynamic (MHD) flow of ionic solutions, which is caused by externally injected electrical current to an imaging media, during MRI scans. A multi-physics (MP) model is created by using the electrical current, laminar flow, and MR equations. The conventional spoiled gradient echo MRI pulse sequence with bipolar flow encoding gradients is utilized to encode the MHD flow. Using the MP model and the MRI pulse sequence, relationship between the MHD flow rela...
