Abstract
- This paper proposes an asymmetric ultra-wideband - radio frequency identification (UWB-RFID) tag with electrocardiogram (ECG)-sensing capability for patients remote-monitoring in hospital environment. A UWB-RFID communication protocol is suggested for real-time transmission of undistorted ECG by interleaving ADC sampling and burst-mode UWB transmission. The proposed system shows a maximum accessing capability of 400 tags/second at 1.5 KHz ECG sampling rate with 10 Mbps UWB pulse rate. The tag consists of UHF-RFID receiver, UWB transmitter, ECG analog front-end, multi-input ADC and baseband circuitry integrated on two silicon dies. It was implemented by 6 mm2 -sized 180 nm CMOS technology. Electrodes for ECG-sensing are manufactured by inkjet-printing on polyimide substrate. Experiment results show that the tag transmits UWB pulses at 1 Mbps rate with 18 µW power. The printed electrodes conduct ECG waveform comparable to commercial electrodes.
