Proposed, to the best of our knowledge, is the first extreme environment wireless all-in-one hybrid temperature plus pressure sensor using a remoted thick single crystal Silicon Carbide chip within a pressurized capsule. Analysis and experiments are reported for the pressure aspect of the sensor for pressures up-to 40 atms.Proposed, to the best of our knowledge, is the first extreme environment wireless all-in-one hybrid temperature plus pressure sensor using a remoted thick single crystal Silicon Carbide chip within a pressurized capsule.
