Micromechanical characterization of photomechanical materials
Abstract
This proposal seeks funding to acquire a system for micromechanical characterization ofphotomechanical materials that fills the sig nificant gaps in both forces, from nano- to milli-Newtons, and lengths, from micrometers to millimeters, that exist between charact erizationtechniques at the single molecule and the macroscopic levels. We propose the purchase of acommercial instrument that inte grates highly sensitive capacitive force transducers based onmicro-electromechanical systems (MEMS) technology with piezoelectric p ositioners and anoptical microscope with adjustable viewing direction to enable a wide range of measurements onmicro-scale photome chanical materials. To the existing system, we will add a multi-wavelengthlight source permitting in situ photo-switching of a rang e of materials. These capabilities willaccelerate the pace of fundamental discovery by providing access to previously unobtainable measurements on individual micro-crystalline structures, and by allowing us to rapidly screenmany candidate materials using only sm all quantities to identify the most promising materials forscale-up to enable macroscopic testing.
