    Abstract: Disclosed is a method for producing zinc oxide nanostructures, the method comprising: providing a zinc anode and a cathode in an arc discharge chamber, wherein the cathode is arranged horizontally in the arc discharge chamber and the anode is arranged vertically; supplying current to the anode and the cathode to establish an arc discharge between the cathode and the anode to vaporise the anode and produce the zinc oxide nanostructures; terminating the current supply to the anode and the cathode; and collecting the resulting zinc oxide nanostructures. Also disclosed is a method for producing a sensor component, the method comprising: providing a sensor substrate comprising a conducting thin film at least partially covering at least two regions on at least one surface of a sensor substrate material to define a gap in the conducting thin film; applying a mixture comprising zinc oxide nanostructures and a nonionic polymer to at least a portion of the gap in the conducting thin film and thereby bridge the gap; and optionally, annealing the mixture of zinc oxide nanostructures and nonionic polymer applied to the sensor substrate, to provide the sensor component. Further disclosed is a sensor component comprising: a sensor substrate comprising a conducting thin film at least partially covering at least two regions on at least one surface of a sensor substrate material to define a gap in the conducting thin film; and a mixture comprising zinc oxide nanostructures and a nonionic polymer covering at least a portion of the gap in the conducting thin film, thereby bridging the gap.

    Abstract: Disclosed is a magnetometer (100) for measuring an external magnetic field. The magnetometer is comprised of at least one core (102), at least one excitation coil (106a, 106b) and at least one pick-up coil (104). The core (102) has a magnetoresistance property measurable in response to the external magnetic field. The at least one excitation coil (106a, 106b) is near or around the core (102) or at least one of the cores (102). The excitation coil (106a, 106b) is configured to be driven by an alternating current to partially saturate a magnetisation of the core (102) during part of the AC cycle. The at least one pick-up coil (104) is near or around at least a portion of the core (102) and the excitation coil (106a, 106b). The pick-up coil (104) is configured to carry a signal induced in the presence of the external magnetic field. The induced signal is measurable in response to the external magnetic field.
