RFID-Enabled Temperature Sensor

I.M. Abdel-Motaleb[1], K. Allen [1]
[1]Department of Electrical Engineering, Northern Illinois University, DeKalb, IL, USA

The design of a RFID-enabled temperature sensor is described in this paper. In this sensor, a change in temperature causes structural beams to bend, which results in a proportional displacement of the plates of the capacitor. Plates\' displacement results, in turn, in changing the value ... En savoir plus
