Abstract: A method of making a shape-programmable liquid crystal elastomer. The method includes preparing an alignment cell having a surface programmed with a plurality of domains. A cavity of the alignment cell is filled with a monomer solution. The monomers of the monomer solution are configured to align to the surface of the alignment cell. The aligned monomers are polymerized by Michael Addition. The polymerized monomers are then cross-linked to form a cross-linked liquid crystal elastomer. The cross-linking traps monomer alignment into a plurality of voxels with each voxel having a director orientation.

Abstract: This application discloses a method of photomechanically manipulating optically fixable SMPs that employ glassy, photoresponsive polymeric materials, which are capable of rapid optical-fixing with short exposures (<<5 min) of eye-safe visible light. Key to the optical fixing is the use of polymeric materials composed of covalently attached photochromic units such as azobenzene and the use of light capable of inducing simultaneous trans-cis and cis-trans isomerization of azobenzene or other photochromic moieties capable of similar cycling. Upon exposure to light in this wavelength regime (440-514 nm for the azobenzene unit here), real and lasting reconfigurations are induced capable of fixing both the optically induced strain as well as mechanically induced strain. A linear dependence of bending angle on polarization angle is observed and may be used to control the shape reconfiguration of the SMPs.

The processor is used to perform the steps of determining exposure settings using the exposure control system; selectively engaging the image stabilization system responsive to whether the determined exposure settings satisfy a predefined condition; capturing a digital image of a scene using the image sensor and the selectively engaged image stabilization system; and storing the captured digital image in the memory system.

Abstract: Cross-linked polyimides based on a novel crosslinker and methods of making the same. The general structure of these heat-resistant and amorphous polyimides is shown as follows: in which n, m, and l denote the degrees of polymerization (DP) of each arm and the linking group R? is one of the following moieties: —C(CF3)2—, —O—, —SO2—, >C(?O), —OPh-C(CH3)2-PhO-, -(Ph)C(CF3)—, or a direct bond (—). Films (cantilevers) comprising cross-linked polyimides according to the present invention demonstrate photodirected bending upon exposure to linearly polarized light.
