Electrical stunning in the process of slaughtering poultry is used to induce unconsciousness and immobilize the animal for easier processing. Unconsciousness is a function of brain damage. Brain damage has been studied with brain impedance recordings under ischemic conditions. This experiment studies brain impedance as a response to a general epileptiform insult caused by electrical stunning an...

Nitrogen plays a key role in crop yields. Hence, farmers may apply excessive N fertilizers to crop fields, inducing environmental pollution. Crop N monitoring methods have been developed to improve N fertilizer management, most of them based on leaf or canopy optical-property measurements. However, sensitivity to environmental interference remains an important drawback. Electrical impedance has...

1. Introduction The development of a real-time, in-service structural health monitoring and damage detection technique has recently attracted a large number of academic and industrial researchers. The goal of this research is to allow systems and structures to monitor their own integrity while in operation and throughout their lives in order to prevent catastrophic failures and to reduce the co...

The paper proposes results from the investigations of humidity sensing elements based on Bi-doped TiO 2 thin films, prepared by a sol-gel method. Titanium n-butoxide was used as a starting material for the preparation of the experimental samples, and bismuth acetate as doping compound. The samples were sintered at 400°C. Afterwards, the samples were placed into a calibrated humidity chamber and...

Measurement of electrical impedance can discriminate between tissues of different electrical properties. A measurement system with adequate spatial resolution focused on a volume around the tip of a needle or other invasive clinical equipment can be used to determine in which type of tissue the tip is positioned. We have measured the sensitivity zone of a needle electrode with an active electro...

Introduction Several in vitro studies have shown that the electrical impedance of malignant tissues is significantly higher than those of normal and benign tissues. Therefore, impedance imaging has the potential as a diagnostic tool in cancer. Magnetic Resonance Electrical Impedance Tomography (MREIT) is a technique that is used for imaging impedance distribution inside an object noninvasively ...
