Embodiments described herein involve methods of forming an interactive card with indicators on a substrate. A plurality of indicators are formed on the substrate by way of a printed electronics process. A plurality of displaceable regions of piezoelectric material are formed on the substrate by way of a printed electronics process. Electrical interconnections are formed on the substrate by way of a printed electronics process, the electrical interconnections connecting an indicator and an associated displaceable region of piezoelectric material such that displacement of the associated displaceable region of piezoelectric material generates a voltage therein that is provided to the indicator in order to actuate the indicator and thereby indicate displacement of the associated displaceable region of piezoelectric material.

Method of fabricating a card with piezo-powered indicator by printed electronics processes

An embodiment is a method and apparatus to treat surface of polymer for printing. Surface of a polymer having a surface energy modified for a time period to control a feature characteristic and/or provide a hysteresis behavior. A material is printed on the surface to form a circuit pattern having at least one of the controlled feature characteristic and the hysteresis behavior.

Surface treatment of hydrophobic ferroelectric polymers for printing

A method of manufacturing a flexible electronics module includes mounting at least two functional components onto a flexible substrate, forming stretchable electrical interconnects configured to provide connection between the two functional components, and cutting shapes into the flexible substrate to increase an ability of the flexible substrate to stretch and flex, wherein the electrical interconnects to the functional components are placed to avoid the shapes.

Method of manufacturing a flexible electronics module

A first patterned contact layer, for example a gate electrode, is formed over an insulative substrate. Insulating and functional layers are formed at least over the first patterned contact layer. A second patterned contact layer, for example source/drain electrodes, is formed over the functional layer. Insulative material is then selectively deposited over at least a portion of the second patterned contact layer to form first and second wall structures such that at least a portion of the second patterned contact layer is exposed, the first and second wall structures defining a well therebetween. Electrically conductive or semiconductive material is deposited within the well, for example by jet-printing, such that the first and second wall structures confine the conductive or semiconductive material and prevent spreading and electrical shorting to adjacent devices. The conductive or semiconductive material is in electrical contact with the exposed portion of the second patterned contact layer to form, e.g., an operative transistor.

Printed material constrained by well structures and devices including same

A method and structures to achieve improved TFTs and high fill-factor pixel circuits are provided. This system relies on the fact that jet-printed lines have print accuracy, which means the location and the definition of the printed lines and dots is high. The edge of a printed line is well defined if the printing conditions are optimized. This technique utilizes the accurate definition and placement of the edges of printed lines of conductors and insulators to define small features and improved structures.

A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.

An interactive card or the like employs a piezoelectric charge generator (piezo-strip) for temporarily driving an indicator. The piezo-strip may be displaced (bent) in order to generate charge to drive the indicator. Printed electronic processes are utilized to produce the indicator and/or the piezoelectric charge generator The need for a printed battery or supplemental power source is obviated. The card may carry printed indicia which corresponds to the states of the indicator (e.g., indication of a test answer selection). Multiple display elements and selector switches may provide multiple indicator states. Multiple piezo-strips may provide a selection function as well as a rest function. Applications include business cards, greeting cards and novelty items, toys and games, advertising and promotions, testing and education, sensors, and so forth.

An embodiment is a display unit. The display unit includes a substrate layer, a layer of colored fluid on the substrate layer, and a transparent actuator element on the layer of the colored fluid. The layer of colored fluid has a thickness and a color. The transparent actuator element modulates the thickness of the colored fluid upon activated by a force such that the colored fluid is changed from a first state to a second state or vice versa. The modulated thickness provides a variable optical density of the colored fluid.

Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.

Oblique parts or surfaces

A thin film transistor (TFT) structure is implemented. This embodiment is much less sensitive than conventional TFTs to alignment errors and substrate distortion. In such a configuration, there is no need to define gate features, so the layout is simplified. Moreover, the gate layer may be patterned by several inexpensive printing or non-printing methods.

Electronic circuit structure and method for forming same

A method for event sensing employs an event sensor comprising a detector and circuitry, connected thereto, produced by printed electronics processes. Operation may rely on fixed characteristic devices, such as a series resistive chain, or variable characteristic devices such as thin film transistors (TFTs) and the like. A pulse is input to the printed electronic circuitry. The printed electronic circuitry divides the pulse across the various devices comprising the circuitry according to pulse amplitude and pulse width. The circuitry provides an output signal which is provided to a plurality of display elements capable of indicating the division performed at the printed electronic circuitry. In one embodiment, each display element is an electrophoretic display which changes contrast as a function of the applied voltage. Not only the pulse amplitude and pulse width, but the number of pulses applied to the printed circuitry (i.e., sensed by the detector) may be indicated.
