ABSTRACT:
A damage sensor comprises a probe track, a sense track, and a signal generator operable to input a probe signal to the probe track. The probe track and the sense track are electromagnetically coupled by a structure on which they are provided, such that the probe signal induces, in dependence on the degree of electromagnetic coupling between the probe track and the sense track, a sensed signal in the sense track. The magnitude, phase and frequency of the sensed signal can be analysed in order to determine whether and where damage has occurred to the structure.
