Abstract: Embodiments herein relate to systems and devices for measuring analyte presence on graphene varactors, which can be used for analyte sensing in physiological gas samples. In an embodiment, a system for measuring analyte presence on a graphene varactor is included having a capacitance to digital converter (CDC) and a graphene varactor. The CDC can be in electrical communication with the graphene varactor and can be configured to measure the capacitance of the graphene varactor in response to an excitation signal over a plurality of DC bias voltages. Other embodiments are also included herein.

Abstract: A method uses an electromagnetic navigation system, including a number of field transmitters and at least one receiver. The method includes receiving a field signal from the at least one receiver, and the field signal includes a number of different frequencies corresponding to each of the field transmitters. The received field signal is multiplied by a synchronization signal using a frequency-division multiplexing scheme, and the received field signal is integrated over a predetermined sampling interval and converted into an integrated signal having only a desired signal based on the synchronization signal. The integrated signal is outputted for subsequent processing of the electromagnetic navigation system.

Abstract: A sensing apparatus includes a magneto-resistive sensing element and a coil element formed on a first chip, and semiconductor circuitry formed on a second chip. The magneto-resistive sensing element senses magnetic fields, while the coil element is used to reset a magnetic orientation of the magneto-resistive sensing element. The semiconductor circuitry includes a reset circuit that controls the coil element and an amplifier circuit coupled to the magneto-resistive sensing element. The amplifier circuit operates to generate a sensing signal that is proportional to the sensed magnetic fields. The sensing signal is then used to activate the reset circuit.
