Abstract: A sensor device for testing electrical connections using contactless fault detection is disclosed. The sensor device includes: a surface coil comprising a plurality of concentric loops disposed at a first region located away from the electrical connections. The concentric loops generate a first magnetic field passing through the electrical connections, and the first magnetic field is equivalent to that generated by a coaxial intermediate current loop adjacent to the electrical connections based on an excitation current in the surface coil. The sensor device further includes a sensor adapted to detect a second magnetic field at a second region located away from the electrical connections, wherein variations in the detected second magnetic field provide categories of performance of the electrical connections.

Abstract: A sensor device is provided for detecting electrical defects in a device under test (DUT). The sensor device includes a signal line configured to conduct a stimulus signal through a first conductor in the DUT; an inductor connected in series with the signal line for providing an inductance; and a ground line arranged adjacent to the signal line and configured to provide a ground path through a second conductor in the DUT for the stimulus signal conducted through the signal line and the first conductor. A resonance frequency for the signal line is determined based on the inductance and an effective capacitance of the signal line generated in response to the stimulus signal. An increase in the resonance frequency indicates an open defect in the first conductor and/or the second conductor, and a decrease in the resonance frequency indicates a short defect between the first conductor and the second conductor.

Abstract: A method of fabricating at least one electronic circuit component comprises: patterning a conductive material on a fibrous substrate by aerosol jet printing in a pattern corresponding to said at least one electronic circuit component; and sintering the conductive material by hot air sintering. The fibrous substrate may be paper, for example cellulose fibre paper.

Abstract: A wireless power transmitter apparatus including a transmit resonator having a resonant frequency; and a transmit coil located within the transmit resonator; wherein the transmit resonator is configured to inductively couple to a receive resonator having a resonant frequency that is the same as the resonant frequency of the transmit resonator to thereby transmit power to the receive resonator.

Abstract: A non-invasive glucose monitoring apparatus comprises at least one microstrip transmission line (MLIN) component comprising: a microstrip conductor that is arranged relative to a ground plane such that a body part of a user, such as a finger or wrist, is receivable in a space defined between the microstrip conductor and the ground plane, the microstrip transmission line component having an input port; a signal input component for transmitting an input signal to the input port; and a concentration determining component configured to: determine at least one parameter of an output signal of the microstrip transmission line component; and determine, based on a comparison of the at least one parameter to at least one respective calibration curve, a glucose concentration of the user.
