in this work, polypyrrole/ceo2 nanocomposite (nc) was synthesized in the presence of methylorange as a reactive self-degraded soft template. the field emission scanning electron microscopy(fesem) images indicate that the ceo2 nps have a nucleus effect and cause a homogenous ppycore–shell type morphology with an encapsulation of the ceo2 core by the ppy shell. the effect ofnc on acrylic waterbor...

This paper is concerned with a physical model of an interdigitated sensor working in a frequency range from 100 Hz to 10 MHz. A theoretical approach is proposed to optimize the use of the sensor for bioimpedance spectroscopy. The correlation between design parameters and frequency behavior in coplanar impedance sensors are described. CoventorWare software was used to model the biological medium...

Photovoltaic arc faults have led to a number of rooftop fires that have caused significant property damage and threatened the safety of building occupants. In response, Article 690.11 was added to the United States 2011 National Electrical Code, requiring new PV systems on or penetrating a building to include a listed arc fault protection device. Many proposed arc fault detectors utilize freque...

This study quantifies the dynamic attachment and spreading of porcine pulmonary artery endothelial cells (PPAECs) on optically thin, indium tin oxide (ITO) biosensors using simultaneous differential interference contrast microscopy (DICM) and electrical microimpedance spectroscopy. A lock-in amplifier circuit monitored the impedance of PPAECs cultivated on the transparent ITO bioelectrodes as a...

A mismatch in electrode impedance is a common and significant source of artefact electrical spectroscopy systems. We have analysed these artefacts, identifying key parameters the optimisation both current voltage excited used this information to develop new clinical system for investigating muscle anisotropy human limbs, with aim developing biomarkers various pathologies. This instrumentation i...
