Low cost sensors realized using UHF RFID tag

In this letter, a new low cost sensor which realized by UHF RFID tag was proposed. The cost of sensor, which consists of accelerometers and single axis gyroscope, is about 0.1$. The principle was introduced and sensor was realized in this paper. As a proof of concept, test was designed based on the proposed principle. The position and attitude of virtual object (or characters in electronic game) was controlled by the sensor.
