Abstract: A system for monitoring marine animals includes a monitoring tag attachable to a marine animal. The monitoring tag includes a processor, a memory coupled to the processor, at least one communication interface, and at least one sensor. The processor is configured to store readings from the at least one sensor in the memory. The system also includes at least one communication receiver having a processor, a memory coupled to the processor, and at least one communication interface. The at least one communication receiver is configured to float in water. The processor of the monitoring tag is configured to determine, using the at least one sensor, whether the monitoring tag is within a communication range for radio frequency communication with the at least one communication receiver, and to transmit, via the at least one communication interface of the monitoring tag, the stored readings to the at least one communication receiver responsive to the processor of the monitoring tag determining that the monitoring tag is within the communication range for radio frequency communication with the at least one communication receiver.

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.

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.
