Abstract:
Methods are described for addressing the bowing and/or warping of flexible substrates, attached to a rigid carrier, which occurs as a result of the thermal challenges of semiconductor processing. In particular, viscoelastic adhesives are provided which can bond a flexible substrate to a rigid carrier and mediate the thermal mismatch which often is present due to the distinctly different materials properties of most flexible substrates, such as plastic films, with respect to rigid carriers, such as silicon wafers. Assemblies are also provided which are produced according to the methods described herein.
Abstract:
A foldable, waterproof case includes a first wall and a second wall coupled to the first wall. The first and second walls at least partially define a cavity within the case. A lid is coupled to the second wall and is configured to selectively cover the cavity. A hinge is disposed between the first wall and the second wall. The first wall is rotatable relative to the second wall between a first, expanded position of the case and a second, collapsed position of the case. In the first position, the cavity includes a first volume and in the second position, the cavity includes a second volume that is less than the first volume. The hinge provides a waterproof connection between the first and second walls in the first position and in the second position.
Abstract:
In an aspect, the present invention provides stretchable, and optionally printable, components such as semiconductors and electronic circuits capable of providing good performance when stretched, compressed, flexed or otherwise deformed, and related methods of making or tuning such stretchable components. Stretchable semiconductors and electronic circuits preferred for some applications are flexible, in addition to being stretchable, and thus are capable of significant elongation, flexing, bending or other deformation along one or more axes. Further, stretchable semiconductors and electronic circuits of the present invention are adapted to a wide range of device configurations to provide fully flexible electronic and optoelectronic devices.

Abstract:
An origami enabled manufacturing system. The system uses origami design principles to create functional materials, structures, devices and/or systems having an adjustable size and/or shape. An operational device can be coupled to a planar substrate shaped and sized to correspond to a desired origami shape of an origami pattern. A plurality of planar substrates can be coupled together by a plurality of connection members that corresponds to one or more crease of the origami pattern. An array of planar substrates can be formed that convert into a three dimensional structure with origami shape. The resulting three-dimensional structure provides smaller projection area, higher portability and deformability.
Abstract:
A dynamic and refreshable three-dimensional tactile display uses stimulus sensitive hydrogel blocks as pixels to create a touch surface with elevations from a two-dimensional optical image or from stored data. The movable three-dimensional tactiles are powerful in teaching Science, Technology, Engineering, and Mathematics (STEM) materials to visually impaired and blind students.
