Abstract: A method for fabricating a composite film structure, the method includes determining a desired morphology for a metallic layer of the composite film structure, selecting a first metal substrate based on the determining, transferring a graphene layer onto the first metal substrate, depositing the metallic layer on the graphene layer to achieve the desired morphology, and removing the first metal substrate from the graphene and the deposited metallic layer to form the composite film structure. A surface energy difference between the first metal substrate and the deposited metallic layer results in the desired morphology of the metallic layer.

Abstract: A sensor arrangement for determining at least one physical parameter of a sensor unit which is activated by at least one periodic excitation, comprising a detection region in which changes of the parameter in the surroundings of the sensor unit lead to an output signal from the sensor unit. The sensor unit is wired such that if there is no change of the parameter in the detection region the output signal is a zero signal at the output of the sensor unit, whereas if there are changes of the parameter in the detection region the output signal is a signal that is not zero and which has a specific amplitude and phase. By means of a closed-loop control, the non-zero signal in the receive path is adjusted to achieve an adjusted state at zero even in the presence of changes of the parameter in the detection region. Inherent in the control signal used for this adjustment is a deviation (Δx, Δy) of the control signal from the adjusted state, which deviation represents information about the parameter. To create a sensor arrangement and a method in which values of a physical parameter in a detection region can be clearly determined, in a four-quadrant representation of the deviation (Δx, Δy) in the form of a vector analysis in a phase space of the control signal, the angle of an imaginary vector (2.6) relative to the x axis of an x, y coordinate system, said vector leading from the origin (2.7) of the x, y coordinate system to a measuring point (2.5) and said origin corresponding to the adjusted state, represents a measurement for the change of the parameter along a direction, and/or the magnitude of the imaginary vector (2.6) represents a measurement for the change of the parameter along a further direction.

Abstract: A control circuit for use with a four terminal sensor, such as a glucose sensor. The Glucose sensor is a volume product and typically its manufacture will want to make it as inexpensively as possible. This may give rise to variable impedances surrounding the active cell of the sensor. Typically the sensor has first and second drive terminals and first and second measurement terminals, so as to help overcome the impedance problem. The control circuit is arranged to drive at least one of the first and second drive terminals with an excitation signal, and control the excitation signal such that a voltage difference between the first and second measurement terminals is within a target range of voltages. To allow the control circuit to work with a variety of measurement cell types the control circuit further comprises voltage level shifters for adjusting a voltage at one or both of the drive terminals, or for adjusting a voltage received from one or both of the measurement terminals.

The chutes and the aquatic animal passage system are formed with precast concrete segments and may include a protective liner or coating coupled to their outer surface to protect animals from contacting the outer surface of the precast concrete segments. The sensors may be integrated with the precast concrete segments forming the chutes. Smart concrete segments may be employed as transducers to create an electric field in the chutes, with impedance sensors coupled to the transducers being responsive to changes to the electric field in the chutes caused by passing animals.

Abstract: A method for conducting nonlinear electrochemical impedance spectroscopy. The method includes quantifying the nonlinear response of an electrochemical system by measuring higher-order current or voltage harmonics generated by moderate-amplitude sinusoidal current or voltage perturbations. The method involves acquisition of the response signal followed by time apodization and fast Fourier transformation of the data into the frequency domain, where the magnitude and phase of each harmonic signal can be readily quantified. The method can be implemented on a computer as a software program.
