Patent ID: 8410924

Claim:
Method for remote monitoring deformations of a structure ( 2 ), which method comprises: coupling at least two RFID tags ( 3 ) to the said structure ( 2 ) in respective points ( 9 a , 9 b ; 9 a - 9 c ) of the structure ( 2 ) itself; interrogating at radio frequency the RFID tags ( 3 ) so that a resultant electromagnetic field is produced at a certain distance (DINF) from said structure ( 2 ), said resultant electromagnetic field ensuing from a combination of the electromagnetic fields singularly produced by the RFID tags ( 3 ) in response to the interrogation; measuring the electromagnetic field at said certain distance (DINF) to obtain measurements of said resultant electromagnetic field; and determining said deformations of the structure ( 2 ) as a function of the measurements of the resultant electromagnetic field.
