Abstract: An efficient fabrication technique, including an optional design step, is used to create highly customizable wearable electronics. The method of fabrication utilizes rapid laser machining and adhesion-controlled soft materials. The method produces well-aligned, multi-layered materials created from 2D and 3D elements that stretch and bend while seamlessly integrating with rigid components such as microchip integrated circuits (IC), discrete electrical components, and interconnects. The design step can be used to create a 3D device that conforms to different-shaped body parts. These techniques are applied using commercially available materials. These methods enable custom wearable electronics while offering versatility in design and functionality for a variety of bio-monitoring applications.

When executing the instructions, the processors present on a display of the apparatus a first screen that corresponds to a first mode of the apparatus. The first screen is in a first level of a graphical user interface (GUI) hierarchy and occupies a substantial portion of the display when presented. In response to a transition event at the first screen, the processors present a second screen that corresponds to a second mode of the apparatus. The second screen is in the first level of the GUI hierarchy and occupies the substantial portion of the display when presented. In response to a selection event at the first screen, the processors present a third screen that corresponds to a first function of the first mode of the apparatus.

Abstract: An edible structure may comprise a gelatin film and fiber strips. The gelatin film may have a higher density of gelatin in a first layer of the film than in a second layer of the film. The fiber strips may be attached to the first layer, and may have an initial orientation, thickness and density. The structure may be configured to undergo a shape transformation when the apparatus hydrates. During the transformation, the film may transform from a flat film into a curved, 3D film. Which specific shape results from the transformation may depend, at least in part, on the initial orientation, thickness and density of the fiber strips. The film may include flavorings or other additives. In some cases, the transformation may change a texture of the structure. In some cases, the transformation may be caused, at least in part, by a change in temperature.

Abstract: In exemplary implementations of this invention, a shape controller controls the shape of a bladder as the bladder inflates. The shape controller includes a first set of regions and a second set of regions. The second set of regions is more flexible than the first set of regions. The shape controller is embedded within, or adjacent to, a wall of the bladder. When the bladder is inflated, the overall shape of the bladder bends in areas adjacent to the more flexible regions of the shape controller. For example, the shape controller may comprise paper and the more flexible regions may comprise creases in the paper. Or, for example, the more flexible regions may comprise notches or indentations. In some implementations of this invention, a multi-state shape display changes shape as it inflates, with additional bumps forming as pressure in the display increases.

Abstract: A composite film includes a substrate that is not responsive to relative humidity, and also one or more layers of hygromorphic material. The hygromorphic material expands in response to an increase in relative humidity and contracts in response to a decrease in relative humidity. In some cases, the composite film is bi-layer or tri-layer. The composite films are fabricated such that they undergo a desired bending pattern in response to changes in relative humidity. In some cases, these bending patterns are combinations of two bending primitives: a smooth curve and a sharply angled curve. These two primitives are combined to create a variety of shape transformations including 1D linear transformation, 2D surface expansion and contraction, 2.5D texture change and 3D folding. Any type of hygromorphic material may be employed, including living gram positive and gram negative bacterial cells, yeast cells, plant cells, mammalian cells, cell debris, or hydrogel.
