(DURIP-20) PROGRAMMABLE VARIABLE ANGLE PHOTO-THERMO-MECHANICAL TESTING SYSTEM FOR CHARACTERIZING PHOTO ADAPTIVE MATERIALS
Abstract
This proposal aims to establish new characterization capabilities for designing and investigating non- conventional Artificial Homeostatic Multifunctional Material Microsystems that are capable of real- time sensing-and-adapting to regulate local conditions including temperature, air pressure, and light at a constant level against environment perturbations. This will enable the research capability and enhance the research quality of a AFOSR YIP project, titled “Bioinspired Artificial Homeostatic Multifunctional Material Microsystems (AHM3) based on Self-sustaining Autonomic Adaptive Structures” (Award Number: FA9550-17-1-0311). Achieving such real-time autonomous regulation of local light conditions relies on creating a series of smart hydrogel materials photo-thermo- mechanically responsive to varying incident photonic stimuli. Critical to the success of this non- conventional autonomic adaptive system development is to carefully and systematically characterize multiple parameters simultaneously, specifically to (1) illuminate the photo-responsive material from different and constantly varying angles and at the same time (2) real-time capture the microscale actuation and analyze reconfiguration three-dimensionally and quantitatively measure (temporal factor) and map (spatial factor) the local temperature and configuration. However, there is no commercial equipment that allows for multifunctional visible-and-IR orthogonal imaging plus thermal/optical measurements with precise environment control. Hence, herein we propose to build a multifunctional dynamic microsystem testing platform, based on a variable-angle illuminating system equipped with a thermal controller and a mechanical tester.
