Abstract:
A method of forming a curved touch surface is disclosed. The method can include depositing and patterning a conductive thin film on a flexible substrate to form at least one touch sensor pattern, while the flexible substrate is in a flat state. According to certain embodiments, the method can include supporting the flexible substrate in the flat state on at least one curved forming substrate having a predetermined curvature; and performing an anneal process, or an anneal-like high-heat process, on the conductive thin film, wherein the anneal process can cause the flexible substrate to conform to the predetermined curvature of the at least one curved forming substrate. According to an embodiment, the curved forming substrate can include a first forming substrate having a first predetermined curvature and a second forming substrate having a second predetermined curvature complementing the first predetermined curvature.
Abstract:
A flexible printed circuit board is provided including a flexible sheet having at least one electrically conductive layer, with a printed circuit pattern and a fold retainer pattern formed in one of the electrically conductive layers. The fold retainer pattern is electrically isolated from the printed circuit pattern. The fold retainer pattern has notches that indicate where the sheet is to be folded when the flexible sheet is folded, it is held in its folded shape by the fold retainer pattern.
Abstract:
Some forms relate to a stretchable computing device that includes a stretchable body; a first electronic component embedded within the stretchable body; a second electronic component embedded within the stretchable body; and wherein the first electronic component and the second electronic component are connected by stretchable electrical connectors that include vias. The stretchable electrical connectors are non-planar and/or may have a partial zig-zag shape and/or a partial coil shape. In some forms, the stretchable computing device further includes a textile attached to the stretchable body.
Abstract:
A wearable device includes a flexible printed circuit board and one or more conductive stiffeners. The conductive stiffeners include a conductive surface that can be electrically or thermally connected to contact pads on the flexible printed circuit board. The wearable device can further include an adhesive layer or an encapsulation layer. The adhesive layer and the encapsulation layer can include conductive portions surrounded by non-conductive portions. The conductive portions can be aligned with the conductive stiffeners and together transmit electrical and/or thermal energy to the contact pads of the flexible printed circuit board.
Abstract:
Die Erfindung betrifft eine abwinkelbare und/oder abgewinkelte Leiterplattenstruktur mit wenigstens zwei winkelig zueinander anordenbaren bzw. angeordneten Leiterplattenabschnitten, wobei die Leiterplattenstruktur wenigstens ein zumindest überwiegend in der Leiterplattenstruktur eingebettetes Leitungselement enthält, das sich zwischen zwei Anschlussstellen erstreckt und mit diesen Anschlussstellen elektrisch leitend verbunden ist, wobei sich die beiden Anschlussstellen auf verschiedenen Leiterplattenabschnitten befinden, wobei die Leiterplattenabschnitte unter Beibehaltung der Verbindungen zwischen den Anschlussstellen und dem wenigstens einen Leitungselement und unter Biegung des wenigstens einen Leitungselements über eine Biegekante zwischen den Leiterplattenabschnitten gegeneinander abwinkelbar und/oder abgewinkelt sind. Um die elektrische und mechanische Verbindung zwischen den Leiterplattenabschnitten zu verbessern, ist erfindungsgemäß vorgesehen, dass das Leitungselement im Querschnitt gesehen entlang der Biegekante eine größere Erstreckung aufweist als senkrecht dazu. Ein entsprechendes Verfahren zur Herstellung dieser Leiterplattenstruktur wird ebenfalls beansprucht.

Abstract:
A mobile computing device includes a flexible display, a rigid-flex printed circuit board (PCB) arrangement, an electrically conductive memory fabric, and a controller. The rigid-flex PCB arrangement is connected to the flexible display, and has a honeycomb configuration. The electrically conductive memory fabric is connected to the flexible display and the rigid-flex PCB arrangement. The controller is configured to, by selectively controlling supply of electrical current to the electrically conductive memory fabric, control whether the electrically conductive memory fabric (i) straightens and resists flexing of the flexible display and the rigid-flex PCB arrangement or (ii) is relaxed and allows flexing of the flexible display and the rigid-flex PCB arrangement.
