The invention relates to a device for detecting icing and de-icing of a wind turbine blade, characterized in that it comprises: a sensor, placed on the surface of a blade, and comprising a first so-called 'receiving' antenna, a second so-called 'emitting' antenna, and a frequency divider inserted between said first and second antennas; and an interrogator, configured to emit an electromagnetic wave towards the receiving antenna of said sensor, and to receive an electromagnetic wave from the emitting antenna of said sensor.

Method for detecting icing and de-icing

A method for monitoring a civil engineering construction including a first metal reinforcement and a reference conductor element. The first metal reinforcement and the reference conductor being separated by dielectric material and each having a first end that is electrically accessible. The method including injecting an incident electrical signal which is applied differentially between the first ends of the first reinforcement and of the reference conductor element collecting reflected signals returning along the conductors in return, and analyzing the reflected signals by comparing them against reference signals in order to determine any potential structural defect in the first reinforcement.
