Core temperature measurement using inductively coupled noise thermometry at 522MHz

Abstract

Every material which dissipates electrical energy generates thermal noise power that is related to the temperature of that material. This work exploits this effect to measure the average absolute temperature within a vessel. We present a technique for the measurement of core temperature based on inductive noise telemetry; where a loop antenna is magnetically coupled to a saline solution. Dissipations in the antenna are dominated by the solution and therefore the noise measured in the antenna is dominated by the noise in the solution. This work demonstrates a noise measurement of 0.67 pV/°C/VHz, approaching the theoretical calculated noise in the solution. The noise thermometry system is demonstrated, in ideal conditions and a temperature measurement resolution of 0.2°C is achieved.
