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.

拟议的研究计划将对实现低成本，低功率有机电子设备，智能，一次性感觉微系统产生重大影响，并将为有机半导体设备的几个新兴应用领域做出贡献。长期的视觉是通过迭代设计和制造过程，明智的聚合物基材料选择和开发物理模型将晶体管特性与可检测的感觉响应相关联的物理模型，建立有机晶体管微型系统的理想配置。短期目标包括：1）发达有机晶体管的电和机械性能的数值估计和物理表征； 2）研究有机半导体和基于聚合物的高K纳米复合介电材料的低成本，直接造成的最佳微生物技术； 3）设计，制造和实验验证有机电化学晶体管（O-ECT）设备，用于主动传感应用。重点是将有机晶体管整合在新型整体和混合构型中，以检测化学分析物和物理变量，以进行潜在的化学，生物学和环境传感应用。该计划将与行业，非营利合作伙伴以及国家和国际研究小组建立合作，并将重点放在实施O-ECT作为化学和生物传感器，培训25位PHD，3个MASC和4名本科生的有机半导体学生实验室。拟议的研究计划将培训HQP的微型/纳米化和表征，以实施有机电子产品的共聚物半导体，导体和介电材料，开发用于低成本，内部O-ECT的新颖方案，O-ECT设备的表征，O-ECT设备和O-ECT设备的表征和随之而来的实验室芯片微型系统。该研究计划是由加拿大成为这种新兴智能传感器技术中的世界领导者的机会，而研究计划与省级和联邦政府的开拓性研究良好联系很好地联系在一起。领域。迫切需要在开发智能，自主和低成本的感觉设备方面接受培训的HQP，这可以促进许多不同构型中的物理和化学分析物的持续测量。我要求DND/NSERC补充剂在研究计划涉及“高级传感”目标区域，更具体地说是化学生物学 - 放射学传感“研究主题”的主题。开发的传感器将提供所需的多功能性，并可以作为制服上的斑块连接，在头盔上以徽标印刷，并将其固定在眼饰框架上以检测有害化学剂，并监测生物标记以快速诊断。
