  • Publication number: 20210208019
    Abstract: A leak detector includes a leak sensor. The leak sensor includes a bottom ground plane, a porous bottom dielectric substrate arranged on the bottom ground plane, a conductor arranged on the porous bottom substrate, a top dielectric substrate arranged on the conductor, and a top ground plane arranged on the top dielectric substrate. The leak detector also includes readout circuitry electrically coupled to the conductor. The readout circuitry is configured to measure a change in electrical properties in at least the porous bottom dielectric substrate.

  • Publication number: 20200011725
    Abstract: A sensor includes a planar T-resonator and an oscillator. The planar T-resonator can be a branched T-resonator with at least two symmetrical branches coupled to a stub. The oscillator has an input coupled to the planar T-resonator and an output. The oscillator has a negative resistance within a predetermined frequency range. The oscillator can be configured so that it has an input phase approximately equal to a phase of the planar T-resonator over a majority of the predetermined frequency range.

  • Publication number: 20190353573
    Abstract: An example system is configured to detect saturation levels of a target, such as a core sample of a reservoir, using magnetic fields generated by hydrophilic magnetic nanoparticles within the target. The target contains both a hydrocarbon, such as oil or gas, and a mixture comprised of water and the hydrophilic magnetic nanoparticles. The system includes magnetic field detectors for spatial distribution across a dimension of the target. The magnetic field detectors are configured to detect a magnetic field associated with the hydrophilic magnetic nanoparticles.
