Abstract
An onboard system for detecting a temperature of an element includes a radio-tag, the radio-tag being fixed onto the element and having an antenna, the antenna having a load, and a radio-tag reader. The radio-tag reader is designed to emit an interrogation signal and to receive in return a response signal coming from the radio-tag. The load includes a thermistor and the radio-tag reader is adapted for determining a gain and/or a phase-shift between the interrogation signal and the response signal and for deducing a temperature of the element therefrom.
