The proposed research program will have significant impact in realizing low-cost, low-power organic electronic devices, smart, disposable sensory microsystems, and will contribute to several emerging application domains of organic semiconductor devices. The long-term vision is to establish the ideal configuration of organic transistor microsystems through iterative design and fabrication process, judicious selection of polymer-based materials and the development of a physical model correlating transistor characteristics with detectable sensory responses. The short-term goals encompass: 1) numerical estimation and physical characterization of the electrical and mechanical properties of the developed organic transistors; 2) investigation of optimal microfabrication techniques for low-cost, direct-patterning of organic semiconductors and polymer-based high-K nanocomposite dielectric materials; and 3) design, fabrication and experimental validation of prototype organic electro-chemical transistor (O-ECT) devices for active sensing applications. The emphasis will be to integrate organic-transistors in novel monolithic and hybrid configurations, for detecting chemical analytes and physical variables, for potential chemical, biological and environmental sensing applications. Establishing collaborations with industry, non-profit partners, and national and international research groups, the program will place emphasis on implementing O-ECTs as chemical and biological sensors, training a total of 2 PhD, 3 MASc and 4 undergraduate students at the Organic Semiconductor Lab. The proposed research program will train HQPs in micro/nanofabrication and characterization, implementing copolymer semiconductor, conductor and dielectric materials for organic electronics, developing novel protocols for low-cost, in-house production of O-ECT, characterization of O-ECT devices and resultant lab-on-a-chip microsystems.******The research program is motivated by the opportunity for Canada to become a world-leader in such emerging smart sensor technologies and the research program links well with both the provincial and federal mandates of pioneering research in this domain. There is an urgent need for HQP trained in developing smart, autonomous and low-cost sensory devices, which can facilitate continuous measurement of physical and chemical analytes in many different conformations. ******I am requesting the DND/NSERC supplement as the research program addresses the 'Advanced Sensing' target area, and more specifically the Chemical-Biological-Radiological Sensing' research theme. The developed sensors will offer desirable versatility in form factor, and can be attached as patches on uniforms, printed as logos on helmets, and secured onto eye-wear frames for detection of hazardous chemical agents, as well as monitoring bio-markers for rapid diagnosis.

该研究项目将对实现低成本、低功耗有机电子器件、智能、一次性传感微系统产生重大影响，并将为有机半导体器件的几个新兴应用领域做出贡献。长期愿景是通过迭代设计和制造工艺，明智地选择聚合物基材料以及开发将晶体管特性与可检测的感官响应相关联的物理模型，建立有机晶体管微系统的理想配置。短期目标包括：1)所开发的有机晶体管的电学和力学性能的数值估计和物理表征；2)低成本、直接图案化有机半导体和聚合物基高k纳米复合介电材料的最佳微加工技术研究；3)设计、制造和实验验证用于主动传感应用的原型有机电化学晶体管（O-ECT）器件。重点将是在新的单片和混合配置中集成有机晶体管，用于检测化学分析物和物理变量，用于潜在的化学，生物和环境传感应用。该项目将与工业界、非营利合作伙伴以及国内和国际研究团体建立合作关系，重点是将O-ECTs作为化学和生物传感器，在有机半导体实验室培养2名博士、3名硕士和4名本科生。拟议的研究计划将培训HQPs在微/纳米制造和表征，实现有机电子的共聚物半导体，导体和介电材料，开发低成本的新协议，内部生产O-ECT，表征O-ECT设备和由此产生的芯片上的实验室微系统。******该研究项目的动机是加拿大有机会成为这种新兴智能传感器技术的世界领导者，该研究项目与该领域的省级和联邦开创性研究任务密切相关。目前迫切需要在开发智能、自主和低成本传感设备方面受过培训的HQP，这些设备可以促进对许多不同构象的物理和化学分析物的连续测量。******我正在申请DND/NSERC补充文件，因为研究项目涉及“先进传感”目标领域，更具体地说，是“化学-生物-放射传感”研究主题。开发的传感器将提供理想的多功能性，可以作为贴片贴在制服上，作为标志印在头盔上，并固定在眼镜框架上，用于检测危险化学剂，以及监测生物标志物以进行快速诊断。
