  • Abstract
    In this paper, a simple wireless platform to transduce data from sensors without the need for a battery in the sensors is introduced. The sensor can be either resistor-or capacitor-based. The sensing systems adapt RFID operation principles including a reader and a transponder. Our platform is fully analog and contains few components making it easy to implement with existing ICs and sensors. The platform for temperature sensing has been demonstrated. The device includes a 1times2.5 cm2 coil antenna and a thermistor. The read range is 4 cm using a 6times6 cm2 reader antenna powered at 970 kHz. A temperature range of 5-90degC is monitored resulting in read frequencies from 6 to 10 kHz.
