Abstract: Zirconia solid electrolytes with nonequilibrium composite structure were prepared by impregnation of a porous 8YSZ matrix with a solution of Zirconia. Microstructures were characterized by XRD and SEM. The electrical properties were studied by impedance spectroscopy as a function of temperature. Biaxial flexural strength and fracture toughness of composite samples were measured by rin...

Introduction: Electrical impedance tomography (EIT) is a non-invasive technique utilized in various medical applications, including brain imaging and other neurological diseases. Recognizing the physiological and anatomical characteristics of organs based on their electrical properties is one of the main applications of EIT, as each variety of tissue structure has its own electrical characteris...

Non-invasive single cell analyses are increasingly required for the medicaldiagnostics of test substances or the development of drugs and therapies on the single celllevel. For the non-invasive characterisation of cells, impedance spectroscopy whichprovides the frequency dependent electrical properties has been used. Recently,microfludic systems have been investigated to manipulate the single c...

This paper investigates the effects of annealing of the electrodes based on parylene-caulked polydimethylsiloxane (pc-PDMS) in terms of mechanical strength and long-term electrical property. Previously, the electrodes based on pc-PDMS showed a better ability to withstand in vivo environments because of the low water absorption and beneficial mechanical properties of the substrate, compared to n...

The structures of αand β-Ag3VO4 were studied via singlecrystal X-ray diffraction (XRD). The transition from α-phase to β-phase was found to occur at 110 °C. Single-crystal XRD revealed that the integrity of the single crystals was maintained as Ag3VO4 reversibly transitioned between α-Ag3VO4 and β-Ag3VO4. The optical and electrical properties of polycrystalline α-Ag3VO4 were studied by diffuse ...

Electrical impedance measurements provide useful information about the characteristics of a Li-ion battery. The classical method of measurement consists in performing an impedance spectroscopy relying on offline records of the response of the battery to a controlled current or voltage test signal. This method is robust but presents an important drawback: it is very time consuming, especially fo...

In this paper, we describe the design and function of a microchip which is used to detect, analyse and count single micron-sized particles at high speed. The device uses multi-frequency electrical impedance together with single particle fluorescence spectroscopy. Impedance is measured using microelectrodes fabricated within a microfluidic channel. Optical measurements are made by focussing a be...

In impedance spectroscopy of epithelial cell layers, it is a common task to extrapolate discrete two-dimensional plots in order to determine electrical properties associated with axis intercepts. Here, we investigate how implicit properties of such curves can be used to predict the x-axis intercept where explicitly determined properties fail to do so. We perform feature extraction, algorithmic ...
