Abstract:
A method of forming a structural honeycomb includes cutting and folding a substrate sheet according to predetermined cutting and folding patterns and fold angles that cause the sheet to form a honeycomb having cells that each have at least one face abutting, or nearly abutting, the face of another cell. The honeycomb is then stabilized by joining abutting, or nearly abutting, faces to hold the honeycomb together. The honeycomb may have a prespecified three-dimensional shape. The folding pattern may include corrugation, canted corrugation, or zig-zag folds. Joining may employ fixed and/or reversible joinery, including slotted cross section, tabbed strip, angled strip, integral skin, sewn, or laced. At least some folds may be partially-closed to create bends and twists in the honeycomb structure. Some surfaces of the honeycomb may be covered with a skin or face sheet. The substrate sheet may have flexible electronic traces.

Tamper-respondent assemblies and methods of fabrication are provided which include a tamper-respondent electronic circuit structure. The tamper-respondent electronic circuit structure includes, for instance, a tamper-respondent sensor having at least one flexible layer and paired conductive lines disposed on the at least one flexible layer. The paired conductive lines form, at least in part, at least one tamper-detect network of the tamper-respondent sensor. The tamper-respondent electronic circuit structure further includes monitor circuitry electrically connected to the paired conductive lines to differentially monitor the paired conductive lines for a tamper event. In enhanced embodiments, multiple interconnect vias electrically connect to two or more layers of paired conductive lines and are disposed in an unfolded interconnect area of the tamper-respondent sensor when the sensor is operatively positioned about an electronic component or assembly to be protected.
Abstract:
In one embodiment, the organic light emitting diode (1) comprises a carrier substrate (2) having an organic layer stack for producing light. The organic light emitting diode (1) is electrically connectable via at least one connector (3) as intended. The connector (3) has two main sides (32) situated opposite one another that each have at least two electrical contact pads (31) of the connector (3) located on them. As seen in a cross section perpendicular to the main sides (32) and perpendicular to an insertion direction (x) of the connector (3), the contact pads (31) are arranged both geometrically and with electrical point symmetry, so that incorrect-polarity protection against incorrect electrical connection of the organic light emitting diode (1) is attained.

In certain embodiments, the formed flexible layer(s) may be one or more corrugated layers or one or more flattened, folded layers.
Abstract:
Disclosed are appendage mountable electronic systems and related methods for covering and conforming to an appendage surface. A flexible or stretchable substrate has an inner surface for receiving an appendage, including an appendage having a curved surface, and an opposed outer surface that is accessible to external surfaces. A stretchable or flexible electronic device is supported by the substrate inner and/or outer surface, depending on the application of interest. The electronic device in combination with the substrate provides a net bending stiffness to facilitate conformal contact between the inner surface and a surface of the appendage provided within the enclosure. In an aspect, the system is capable of surface flipping without adversely impacting electronic device functionality, such as electronic devices comprising arrays of sensors, actuators, or both sensors and actuators.
