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.

这项研究的目的是展示一种基于有机晶体管技术的原型射频识别(RFID)标签系统，具有更大的通信范围。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高电源电压传输能力的限制。该方法是制造具有极高迁移率、能够低电压工作的离子凝胶介质有机晶体管，并设计针对这些新器件进行优化的可靠的数字和混合信号电路。这项拟议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。新的可印刷的高电容介质、高迁移率的稳定n型沟道材料以及保证器件可靠性的制造方法将被开发出来。基于离子凝胶器件，每个电路构建块都将针对低电压操作进行优化，并集成到RFID原型中。印刷、柔性RFID电路的制造将使用现成的、直接写入、气雾剂喷印方法来完成。该项目将在可印刷的、灵活的、大面积的电子产品领域产生重大影响。将为本科生和研究生课程开发关于有机晶体管的新课程材料。将准备一个实验模块，同时教授学生有关材料问题和基本晶体管操作的知识。这个跨学科的实验室模块将被纳入材料科学和工程或电气工程的本科实验室课程。该项目将积极主动地招收和培养代表性不足的少数族裔学生、妇女和K-12学生，并大力利用现有的大学范围的外联努力。
