Abstract:
Electronic stickers may be manufactured on flexible substrates (110, 120, 130) as layers and packaged together. The package may then have an adhesive applied to one side to provide capability for sticking the electronic devices to surfaces. The stickers can be wrappable, placed on surfaces, glued on walls or mirrors or wood or stone, and have electronics (112, 122, 132) which may or may not be ultrathin. Packaging for the electronic sticker can use polymer on cellulose manufacturing and/or three dimensional (3-D) printing. The electronic stickers may provide lighting capability, sensing capability, and/or recharging capabilities.
Abstract:
One manner of producing more desirable clothing with electronic capabilities is to manufacture electronics, such as the charging wires or devices themselves, directly onto the textile materials. Textile materials generally do not support the manufacturing of electronic devices, in part because the surface of the textile is too rough for electronic devices or the processes used to manufacturing electronic devices. An intermediate layer (204) may be placed on the textile material (202) to reduce the roughness of the surface of the textile material and provide other beneficial characteristics for the placement of electronic devices (206) directly on the textile material.

Abstract:
Various examples are provided for stretchable antennas that can be used for applications such as wearable electronics. In one example, a stretchable antenna includes a flexible support structure including a lateral spring section having a proximal end and at a distal end; a metallic antenna disposed on at least a portion of the lateral spring section, the metallic antenna extending along the lateral spring section from the proximal end; and a metallic feed coupled to the metallic antenna at the proximal end of the lateral spring section. In another example, a method includes patterning a polymer layer disposed on a substrate to define a lateral spring section; disposing a metal layer on at least a portion of the lateral spring section, the metal layer forming an antenna extending along the portion of the lateral spring section; and releasing the polymer layer and the metal layer from the substrate.

A sensor includes a substrate (105) and a nanotube structure (110) formed on top of the substrate. A body (115) is formed on top of the substrate and surrounds the nanotube structure. A source contact (120) is electrically coupled to a top portion of the nanotube structure. A drain contact (125) is arranged on top of the substrate and is electrically coupled with a bottom portion of the nanotube structure. A gate contact (130) is arranged on top of the nanotube structure. The gate contact is electrically is isolated from the top portion of the nanotube structure and electrically coupled with a middle portion of the nanotube structure. The top portion of the nanotube structure is exposed to an environment surrounding the sensor.
Abstract:
A flexible solar cell (100) includes an interdigitated back contact (508) having a first electrode (102) coupled to a first plurality of contacts (104) and a second electrode (106) coupled to a second plurality of contacts (108). The first plurality of contacts run in a first direction (110) from the first electrode towards the second electrode and the second plurality of contacts run in a second direction (112) from the second electrode towards the first electrode. The flexible solar cell also includes a plurality of light-collecting segments (114) coupled to the first and second plurality of contacts of the interdigitated back contact. Adjacent ones of the plurality of light-collecting segments are spaced apart from each other in the first or second direction. A length of each of the plurality of light-collecting segments runs along the interdigitated back contact in a third direction (116), which is perpendicular to the first and second directions.

Abstract:
The control system (120) is implemented on a base cap (112) of a pill container (102). It is connected to an ingress/egress pill counter (130), which counts the number of pills going into and out of the container. Optionally strain, tamper, container temperature or container humidity sensors can be connected to the control system. Preferably, these are paper sensors. The control system connects to the pills counter and sensors via electrical connections (166, 168). The control system is adapted to generate an alert depending on the signals from the pill counter or sensors. The alert may be generated via Bluetooth functionality, a GSM module, a LED or a buzzer.. Bluetooth functionality allows a 2-way data transmission to a smartphone. A log of sensor and pill intake data may be kept in Flash Memory. A top lid (114) attaching to the base cap fully encloses the control system.
