Abstract :
We demonstrate a microfabricated 63Ni radioisotope-powered RFID transponder realized with a SAW (surface acoustic wave) device as the transmission frequency selector. The transponder is powered by a 1.5 milli-Ci 63Ni source which has a half-life of 100 years. We have achieved a 5mW, 10-¿s long, 100MHz carrier envelope, RF pulses which occur every 3 minutes, across a 50¿ load. The transponder can potentially work autonomously for decades, which can revolutionize long term reliable sensing and monitoring.
