Backscatter RFID sensors are beneficial for sensing applications where small, low-maintenance sensor nodes are needed. In this paper, a transducer to monitor the curvature of a tagged object for backscatter RFID sensors operating at 5:8GHz is presented. It is shown, by vector network analyzer measurements, that the presented prototype, an open-circuited microstrip line resonator, changes its input impedance with bending and thus, proves feasible for integration in an RFID sensor. Analysis of the transducer’s performance, when integrated in a backscatter sensor, is provided.
