文摘

Strain can be successfully extracted independent of the interrogation distance for the first time. The proposed structure allows for strong inductive coupling and, thus, a higher wireless signal-to-noise ratio. Using full electrical characteristics of the system, strain can be precisely extracted at any interrogation distance.
