Abstract: A pneumatic haptic sleeve is provided which is knit in one piece with a top side and a bottom side. The top side has a relatively soft and stiff stiffness areas. The soft areas are of increasing stiffness, where the softest is right beneath pneumatic actuators and allows for actuator deformation. The high stiff area is above and around the pneumatic actuators. The pneumatic actuators fit within the knitted sleeve such that the top side of the pneumatic actuator matches up with the high stiffness area, and the bottom side of the pneumatic actuator matches up with the low stiffness area. The pneumatic actuator has two states: actuated and non-actuated. The pneumatic haptic sleeve is portable, self-contained, and comfortable to wear, thereby promoting extended wearability and more consistent use in mediated social touch applications.

Abstract: A wearable device may be provided for detecting cumulative alcohol consumption. Such a wearable device may include an adhesive layer that adheres to skin and that allows sweat from the skin to pass through and a customizable ink layer that reacts irreversibly to change color along a gradient as ethanol is detected in the sweat. The customizable ink continues to increase color intensity along the gradient as ethanol continues to be detected in the sweat over time.

Abstract: Disclosed is a method for producing an orthodontic appliance for securing to a user's teeth in order to carry out an orthodontic treatment, the appliance having an element. The method includes a) gathering information relating to the user's set of teeth; b) using the information to determine at least first and second stable shapes of the element towards which the element should tend to deform during the first and second periods of treatment, respectively; and c) producing and programming the element in such a way that the application of a stimulus during the first period of the treatment renders the second stable shape operational. In certain aspects in step c), a retractable or expansible material is incorporated into the element.

Abstract: The Self-Assembly System is composed of a series of units that take an external force that activates an individual state in each unit and sequentially folds/rotates/expands to form a rigid 3-dimensional structure. The system self-assembles from a flexible linear chain or 2-dimensional grid pattern into a rigid 3-dimensional structure, simply by adding an external energy source. The mechanism and placement of each unit provides the sequence of fold angles that is activated by external energy. When the system is assembled, unit-by-unit, or pre-manufactured as a single linked strand, the user is actually “programming” the folding sequence, much like our body's protein strands, that take external energy and fold in a 3-dimensional structure. This demonstrates that structures can be built from 1-dimensional or 2-dimensional flexible geometry and self-assemble into 3-dimensional rigid geometry without manual assembly or construction, simply through an external means of energy.
