Sentences with phrase «electrical impedance»

Electrical impedance refers to the opposition or resistance that an electrical circuit or device demonstrates when an electric current flows through it. It is akin to the resistance in a water pipe, where the narrower the pipe or the rougher its surface, the greater the resistance to water flow. Similarly, electrical impedance measures how much a circuit or device resists or hinders the flow of electric current. Full definition
That's the promise of a new technology called electrical impedance tomography, or EIT.
As it moves, the pipette monitors a property called electrical impedance — a measure of how difficult it is for electricity to flow out of the pipette.
Further, studies have shown real - time, label - free cell monitoring using electrical impedance technology to be a viable technique to perform these assays and identify and validate novel cancer targets.
Brian Pollard at the University of Manchester, UK, and colleagues used a new method called functional electrical impedance tomography by evoked response (fEITER) to record the brain activity of 20 people as they responded to a general anaesthetic.
The Prize was awarded for Dr. Rutkove's work to advance the use of electrical impedance myography (EIM) as a biomarker measure for ALS.

Imaging techniques used for diagnosis of pathology (such as ultrasound, mammogram, magnetic resonance imaging (MRI), positron emission tomography (PET) scan, 2 - Methoxy Isobutyl Isonitrile (MIBI) scan, electrical impedance tomography (EIT) scan, computed tomography (CT) scan / computer axial tomography (CAT) scan, thermography, or diaphanography) are non-invasive and do not affect milk production or safety.
To make efficient vibration harvesters from PVDF, researchers must stack the polymer in multiple layers, improving the output current and reducing the electrical impedance that is inherent to piezoelectric materials.
