A Sub-2V Printed Flexible Organic RFID System Design for Long Range Communication

本研究的目的是展示一个基于有机晶体管技术的射频识别（RFID）标签系统的原型，该系统具有改进的通信范围。传统的基于有机晶体管的RFID系统具有有限的通信距离，因为它们从根本上受到提供高电源电压的能力的限制。该方法是制造具有极高迁移率的离子凝胶介电有机晶体管，并为这些新型器件设计优化的可靠数字和混合信号电路。提出的研究将开发关键技术，将有机晶体管技术转化为未来大面积电子系统的可行器件平台。将开发新的可印刷高电容介质，具有高迁移率的稳定n型通道材料以及保证器件可靠性的制造方法。基于离子凝胶器件，每个电路构建块将针对低压操作进行优化，并集成到RFID原型中。印刷柔性RFID电路的制造将使用一种易于获得的，直接写入的，气溶胶喷射打印方法来完成。该项目将在可印刷、柔性、大面积电子领域产生重大影响。将为本科和研究生课程开发新的有机晶体管课程材料。将准备一个实验模块，同时教授学生有关材料问题和基本的晶体管操作。这个跨学科的实验模块将被纳入材料科学与工程或电气工程的本科实验课程。该项目将积极招募和培养代表性不足的少数民族学生、女性和K-12学生，并大力利用现有的全校范围内的推广工作。

The objective of this research is to demonstrate a prototype radio-frequency identification (RFID) tag system based on organic transistor technology with improved communication range. Traditional organic transistor based RFID systems have a limited communication distance as they are fundamentally restricted by the capability of delivering a high power supply voltage. The approach is to fabricate ion-gel dielectric organic transistors with extremely high mobility capable of low-voltage operation and to design reliable digital and mixed-signal circuits optimized for these novel devices. The proposed research will develop key technologies to transform organic transistor technology into a viable device platform for future large area electronic systems. New printable high capacitance dielectrics, stable n-type channel materials with high mobility, and fabrication methods for device reliability assurance will be developed. Each circuit building block will be optimized for low voltage operation based on the ion-gel devices and integrated into an RFID prototype. Fabrication of printed, flexible RFID circuits will be accomplished using a readily available, direct-write, aerosol-jet-printing method. This project will have a major impact in the general arena of printable, flexible, large-area electronics. New course materials will be developed on organic transistors for the undergraduate and graduate curricula. A laboratory module will be prepared that simultaneously teaches students about materials issues and basic transistor operation. This interdisciplinary laboratory module will be incorporated into an undergraduate laboratory course in materials science and engineering or in electrical engineering. This project will proactively recruit and nurture under-represented minority students, women, and K-12 students, and strongly leverage existing university-wide outreach efforts.
