The document summarizes research on using passive chipless RFID tags for remote identification and wireless temperature sensing. It discusses two key points: 1) A novel technique to identify tags based on extracting the terminating load impedance and transmission delay line length from the tag's time-domain response. This allows identifying tags under both line-of-sight and non-line-of-sight scenarios from distances up to 180 cm. 2) The tags can also be used as wireless temperature sensors by incorporating a thermistor and extracting its varying resistance from 20Β°C to 100Β°C using the proposed load extraction methods, successfully sensing temperature changes.
