项目摘要

Economically viable self-powered micro and nano devices promise to revolutionize technologies in healthcare, environmental, consumer and military applications. Piezoelectric nanowires can convert mechanical energy into electrical power, and extend the applications for implanted biomedical devices. They can be used where solar energy is unreliable. However, there are significant roadblocks for nano and micro systems to realize their full potential. Current methods used for making these systems require many discrete processes, expensive equipment in addition to a clean room environment resulting in prohibitive cost. Each process requires long preparation, handling and processing times. For faster throughput, huge investments must be made for automation, justifiable only for mass production. In general, cost has become a roadblock against capturing the benefits of most nanotechnology innovations. Therefore, a need in nanomanufacturing is to develop innovative flexible processes that enable integration for efficient small and medium lot size production. This award is to work on a single equipment that can perform multiple tasks required for processing heterogeneous nanomaterials and integrating them into a device. The non-cleanroom method is scalable and has shown more than two-orders-of-magnitude improvement in zinc oxide nanowire performance, reduction of six processes in to one, and reduction of equipment investment by a factor of ten. This research advances the fundamental understanding of the capabilities and performance of this single-step approach for processing and integrating heterogeneous materials and devices. The project plans to recruit female and under-represented minority graduate students, use the research results in new coursework and organize symposia as a platform for stimulating and exchanging new ideas.The overarching goal of this project is to study and develop a novel integrated nanomanufacturing process for self-powered nanosensor systems. The research involves understanding the process-structure-properties-performance relationships in these materials and systems. The objectives of this research project are to uncover the correlations among the nucleation density, growth and morphology of the ZnO nanowire arrays produced by a pulsed laser; the correlation of the piezoelectric properties and the morphology of the ZnO nanowire arrays; the correlation of the performance of the piezoelectric nanogenerator subassembly and the piezoelectric properties, and the integration of a nanosensor into the self-powered nanogenerator system. The main outcome of this research is the understanding of the mechanisms and relationships among pulsed laser parameters, crystal nucleation and morphology control of ZnO nanowire arrays, and its impact on the material properties and performance in self-powered nanosensing systems.

经济上可行的自供电的微型和纳米设备有望彻底改变医疗，环境，消费者和军事应用中的技术。压电纳米线可以将机械能转换为电力，并扩展植入的生物医学设备的应用。它们可以在太阳能不可靠的地方使用。但是，纳米和微型系统具有巨大的障碍，可以发挥其全部潜力。用于制造这些系统的当前方法需要许多离散的过程，除了清洁室环境外，还需要昂贵的设备，从而导致成本高昂。每个过程都需要长时间的准备，处理和处理时间。为了更快的吞吐量，必须进行巨额投资以进行自动化，这仅适用于群众生产。总的来说，成本已成为抵制大多数纳米技术创新的好处的障碍。因此，纳米制造的需求是开发创新的灵活过程，以使整合有效地增加中等大小的生产。该奖项是处理单个设备，该设备可以执行处理异质纳米材料并将其集成到设备中所需的多个任务。非清洁空间方法是可扩展的，并且在氧化锌纳米线的性能，六个过程中的六个过程中显示了超过两端，将设备投资减少了十倍。这项研究促进了对这种单步方法处理和整合异质材料和设备的能力和性能的基本理解。该项目计划招募女性和代表性不足的少数群体研究生，使用研究结果，并组织研讨会作为刺激和交换新想法的平台。该项目的超大目标是研究和开发一种新型的纳米制造过程，以进行自动驱动的纳米传感器系统。该研究涉及了解这些材料和系统中的过程结构 - 绩效关系。该研究项目的目标是揭示脉冲激光器产生的ZnO纳米线阵列的成核密度，生长和形态之间的相关性；压电特性与ZnO纳米线阵列的形态的相关性；压电纳米生成器子组件和压电性能的性能以及将纳米传感器的整合到自动纳米生成器系统中的相关性。这项研究的主要结果是了解脉冲激光参数之间的机制和关系，ZnO纳米线阵列的晶体成核和形态控制及其对自供电纳米传感系统的材料特性和性能的影响。
