This paper presents a battery-less tire pressure monitoring system. Electro-magnetic field energy harvesting is utilized. The chip is also capable of RFID in a frequency range from 1MHz to 2.45GHz. The sensor data is transmitted either by an active transmitter at 868MHz or by employing the RFID feature. A bulk acoustic wave resonator is used as frequency(More)
This paper presents a fully passive multi frequency RFID transponder according to the EPC HF and EPC Class 1 Gen 2 UHF standard. The combination of inductive and electro-magnetic coupling increases the applicability and flexibility of state-of-the-art RFID transponders especially for these areas of applications where RFID transponders should operate in both(More)
