Patient monitoring is one of the challenging and significant tasks in healthcare sector. Generally bio-potential electrodes are used to extract low amplitude physiological signals from the human body and for continuous healthcare monitoring of patients in hospital. The conventional wet electrodes provide an optimal signal, but it needs skin preparation and the application of electrolytic gel be...

Impedance response of zinc and galvanized steel samples exposed in wet-dry cyclic condition using 0.05 M NaCl solution has been analyzed in order to evaluate their corrosion behavior. The wet-dry cyclic test was performed by exposing sample to alternate conditions of 1 h immersion in 0.05 M NaCl solution and 7 h drying at 298 K with relative humidity (RH) of 60% for 10 days consisting of 30 cyc...

This paper presents a biosensor-CMOS platform for measuring the capacitive coupling of biorecognition elements. The biosensor is designed, fabricated, and tested for the detection and quantification of a protein that reveals the presence of early-stage cancer. For the first time, the spermidine/spermine N1 acetyltransferase (SSAT) enzyme has been screened and quantified on the surface of a capa...

Decreasing transistor sizes and lower voltage swings cause two distinct problems for communication in integrated circuits. First, decreasing inter-wire spacing increases interline capacitive coupling, which adversely affects transmission energy and delay. Second, lower voltage swings render the transmission susceptible to various noise sources. Coding can be used to address both these problems....

background: this study is the first research investigating the possible effect of pulsed power signals on the characteristics of cortical bone by comparing the mechanical properties of this type of bone pre and post expose to pulsed power. methods: a positive buck-boost converter was applied to generate adjustable high voltage, high frequency pulses (up to 500 v and 10 khz). the functional beha...

Introduction: Decoupling of multi-element coil is becoming increasingly important due to the parallel transmitting application. The conventional method to decouple coil elements distributed in the azimuthal direction is to use the Butler matrix to form the Eigen modes of the multi-element set-up [1]. Because the Eigen modes of the birdcage coil are orthogonal to each other, the elements after B...

Radio frequency (rf) plasma sources used in the processing of thin films can be divided into three distinct categories: capacitive (E), inductive (H), and wave (W) -sustained (e.g., helicon) discharges. As the excitation power or voltage is increased, transitions from capacitive to inductive to helicon discharges are often observed, in some cases exhibiting hysteresis. A model is developed to d...

there are fewer problems encountered with optical voltage transducers in comparison with their inductive and capacitive counterparts. although capacitive and inductive transformers are used vastly for the purpose of measurement and protection in the networks, they cause problems such as core saturation and improper transient responses which decrease the accuracy of measurement and eficiency of ...
