제목 Wireless VOCs Sensor Based on Carboxylated Polypyrrole Nanoparticle Fixed Ultra High Frequency (UHF)-RFID Tag
초록 In this study, we fabricated radio frequency identification (RFID)-based wireless sensor systems using carboxyl group functionalized polypyrrole (C-PPy) nanoparticles (NPs). The sensor system was composed of an RFID reader antenna and a C-PPy NPs coated sensor tag made from a commercially available ultrahigh frequency (UHF)-RFID tag. The C-PPy NPs were synthesized via chemical oxidation co-polymerization and were covalently bonded to the tag to form a passive sensor. This wireless sensor exhibits ultrahigh sensitivity to ammonia over long distances, detecting concentrations as low as 0.1 ppm. It also maintains its sensing performance as they were deformed by bending and twisting. Due to their flexibility, these sensors may be used in wearable technologies for sensing gases.
