该论文提出了一种基于非晶铟镓锌氧化物薄膜晶体管工艺的柔性NFC标签，可在低于250°C的温度下直接加工在聚酯基底上，旨在实现低成本、低功耗的物联网通信。通过商用USB阅读器设备在13.56MHz频率下为标签供电，解决了传统硅基NFC标签在柔性应用中的成本和工艺兼容性问题。

We employ amorphous Indium-Gallium-Zinc-Oxide (a-IGZO) thin-film transistor circuits processed at low temperatures, less than 250C, directly on thin polyester substrates. Reaching NFC standards with a-IGZO circuits is challenging because the technology is n-type only and the electron mobility (~15 cm2/Vs) is lower compared to silicon. As the main result, we show that the most important NFC regulatory standards are met, even with relaxed 5 micron design rules, using optimized design topologies. The measured data rates and power consumption of all different transponders is
