3D PROFILOMETER FOR INVESTIGATION OF MICRO AND NANOFEATURES OF ADVANCED MATERIALS

我们正在为新的先进材料开发一个通用的3D可视化系统。本资助申请中要求的设备是一台多功能数码显微镜（Keyence VHX-2000数码显微镜），具有3D轮廓测量能力，可用于先进材料和设备的微观和纳米特征的实验研究：聚合物、复合材料、泡沫、骨组织细胞、微流体和光伏。该项目的目标是为多伦多大学新开发的先进制造研究所提供先进材料领域的先进设备，目标有三个方面：1)在实时加工过程中可视化和建模聚合物混合物和复合材料；Ii)精确控制生物医学组织的拓扑结构，特别是用于骨结构适应的微细胞力学测试装置iii)拓扑图案聚合物和超导体表面的微结构表面的精确和自动化深度测量。精确和动态的测量和表征微纳米特征是所要求的系统的主要功能。然而，使用所提出的显微镜，获得这样的测量是可以实现的。测量结果可用于研究各种工艺、材料和系统参数对最终产品/设备性能的影响。本研究项目的应用领域包括：功能泡沫、组织工程、传感器和传感器、光伏和光电子器件。该系统将成为多伦多大学新开发的先进制造研究所开放访问基础设施的一部分。该系统对所有申请人都至关重要，因为它将代表来自多伦多大学各个部门的实验室中最先进的可视化系统：机械与工业工程、材料科学与工程、电气与计算机工程以及生物材料与生物医学工程研究所。

We are making the case for a universal 3D visualization system for new advanced materials development. The equipment requested in this grant application is a multifunctional digital microscope (Keyence VHX-2000 digital microscope) with 3D profile measurement capabilities to be used in experimental studies of micro and nano-features of advanced materials and devices: polymers, composites, foams, bone tissue cells, microfluidics and photovoltaics. The goal of this program is to have state of the art equipment in Advanced Materials for the newly developed Institute for Advanced Manufacturing at the University of Toronto and the objectives are three folds: i) to visualize and model the polymer blends and composites in real time processing; ii) to precisely control the topology of biomedical tissues in particular the micro cell mechano-testing device used in bone structure adaptation iii) accurate and automated depth measurement for microstructured surfaces of topologically-patterned polymer and superconductors surfaces. Accurate and dynamic measurements and characterization of micro and nano-features is the main function of the requested system. Using the proposed microscope, however, the acquisition of such measurements will be achievable. The measurements can be used to study the effects of various processing, material and system parameters on the final product/device properties. Applications in this research program include: functional foams, tissue engineering, sensors and transducers, photovoltaic and optoelectronic devices. The requested system will be part of the open access infrastructure for the newly developed Institute for Advanced Manufacturing at the University of Toronto. The system crucial for all the applicants since it will represent state of the art visualization system in their labs from various Departments units in the University of Toronto: Mechanical and Industrial Engineering, Materials Science and Engineering, Electrical and Computer Engineering and Institute of Biomaterials and Biomedical Engineering.
