The Shape of Electrical Impedance Spectroscopy (EIS) is altered in Stroke Patients
The 26th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2005The shape of the Power Spectral Density Function (PSD) of the Electrical Field Distribution exhibit abnormalities in the brain structure when comparing chronic stroke patients with healthy volunteers. We built a System that can deliver White Noise currents in the 0-25kHz band to any electrode pair.

Barium titanate has been doped with rare earth oxides (erbium, holmium, gadolinium and yttrium), in an attempt to understand the effect upon the reliability of the dielectric material for multilayer capacitor applications. The morphology of the samples used was characterized using scanning electron microscopy (SEM).

Abstract Some inconsistencies were found in the literature on the effect of surfactant type on membrane fouling by surfactant-stabilized oil emulsions. For instance, a recent study showed that the fouling trends revealed by optical coherence tomography (OCT) were incongruent with the flux decline trends.

This paper presents the dielectric behaviour of suspensions of tomato cells (MSK8) and tobacco cells (BY2) in Murashige and Skoog, and Phosphate Buffer solutions. The behaviour of various concentrations of such suspensions is studied over a wide range of frequencies (1 kHz to 20 GHz).

In vivo Electrical-Impedance Spectroscopy (EIS) Readings in the Human Rectum
2016Worldwide, colorectal cancer (CRC) is one of the leading causes of morbidity and mortality, ranking third among the most common cancers. Although screening programs are useful in reducing its impact, the screening tools available at present are far from being ideal.

Glucose Detection Based on Low-Cost Electrical Impedance Spectroscopy (EIS) Using Genetic Algorithm
2018 IEEE ANDESCON, 2018The aim of this work is detecting glucose concentration based on low-cost electrical impedance spectroscopy (EIS) that works in a frequency range until 65 KHz through sine waves generated by a direct digital synthesizer (DDS). This system uses a pass band filter to reduce offset before a voltage to current converter which drives frequencies toward an ...

Breast cancer is considered among the leading causes of mortality and in Mexico is the leading cause of death in women over 25 years. Current limitations in treatment are associated to late diagnosis of the disease. Application of bioimpedance measurements to differentiate mammographic findings has technical feasibility because the electrical ...
