摘要： A low-cost and non-invasive method for remote monitoring deformations of a structure (2), which method envisages to couple at least two RFID tags (3) to the structure (2) in its respective points (10a, 10b, 10a-10c), to interrogate at radio frequency the RFID tags (3) so that a resultant electromagnetic field is produced at a certain distance (DINF) from the structure (2), the resultant electromagnetic field ensuing from a combination of the electromagnetic fields produced individually by each RFID tags (3) in response to the interrogation, to measure the resultant electromagnetic field at such a distance (DINF) from the structure (2) for obtaining measurements of the resultant electromagnetic field, and to determine the deformations of the structure (2) as a function of the measurements of the resultant electromagnetic field.

摘要翻译： 一种用于远程监测结构（2）变形的低成本和非侵入性方法，该方法设想将其至少两个RFID标签（3）耦合到其各自点（10a，10b，10a- 10c），以无线电频率询问RFID标签（3），使得从结构（2）产生一定距离（DINF）的合成电磁场，从单独产生的电磁场的组合产生的所得到的电磁场 通过每个RFID标签（3）响应于询问，以从结构（2）测量所得到的电磁场（DINF），以获得所得到的电磁场的测量值，并确定结构的变形（ 2）作为所得电磁场的测量的函数。
