摘要： A solution for evaluating a medium using electrical signals is described. A plurality of electrical signals having different frequencies are transmitted through the medium and signal data corresponding to the electrical signals after having traveled through the medium is acquired. A complex impedance and a complex permittivity and/or complex conductivity can be calculated for the medium. A set of characteristics of the medium can be computed using mixing models and/or known information of the medium. A level of one or more attributes of the medium can be determined from the characteristics using nonparametric Bayesian inference. One particular application is directed to determining a nitrate level of soil.

摘要： An embodiment in accordance with the present invention is directed to a non-optical, label-free microfluidic biosensor utilizing an electrical liquid interface between two co-flowing liquids - one with a higher conductivity and one with a higher dielectric constant. The analyte-of-interest is in one solution while the receptor is in the adjacent stream. The electric interface acts as a substrate, when an alternating current electric field is applied perpendicularly across the interface, liquid displacement occurs which is frequency dependent. When a reaction occurs at the interface, it alters the electrical properties of the electrical interface, altering the frequency dependent liquid motion, which is then monitored by impedance spectroscopy downstream.

摘要： Systems and methods to provide a low voltage interface coupleable between an energy storage device or a DC power source (e.g., fuel cell stack, battery) and one or more AC signal diagnostic systems. The low voltage interface reduces a voltage of the DC power source and supplies the reduced voltage to the one or more AC signal diagnostic systems without affecting the results of the measurements obtained by the one or more AC signal diagnostic systems. Such functionality provides a safer method for performing advanced analysis (e.g., EIS, frequency analysis) while utilizing lower cost and/or smaller components.

摘要： Method for determining the state of an electrochemical device by means of electrochemical impedance spectroscopy (EIS) and equivalent circuit model (ECM) comprising the steps of measuring the system impedance by any EIS device, modelling the measured impedance by an ECM, identifying the ECM parameters through an automatic minimization algorithm, and processing the ECM parameters values to simulate the electrochemical impedance of the device. In particular, the identifications of the number of parameters (i.e. the ECM model components) and of suitable starting values of these parameters are automatically detected through a geometrical pre-analysis of the shape of the measured impedance spectrum Z', which geometrical pre-analysis will be also called in the following as Geometrical First Guess (GFG) algorithm.
