Wireless and sensitive radio-frequency identification (RFID) tag hydrogen sensor based on Pt nanoparticles decorated graphene |
| 초록 |
Highly sensitive hydrogen-gas leak detection and surveillance systems are needed owing to its high flammability; additionally, the ability to monitor large areas via wireless networks is becoming increasingly important to detect toxic and critical gas as fast as we can. In this report, we introduce radio frequency identification (RFID)-based wireless smart-sensor system, composed of Pt-decorated reduced graphene oxide (Pt_rGO) sheets-immobilized RFID sensor tag and an RFID-reader antenna-connected network analyzer to detect hydrogen gas. The resulting sensor shows high sensitivity to unprecedentedly low concentration (1 ppm) in wireless network system and probability to observe target gas in long distance (50 cm). |
