Abstract

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 senors 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.
