    Abstract: A stacked electronic component comprises a stack of three or more print layers. Each print layer has an area less than any print layers beneath the print layer in the stack. Each print layer comprises a dielectric layer and a functional layer disposed on the dielectric layer. The functional layer comprises an exposed conductive portion that is not covered with a dielectric layer of any of the print layers and each exposed conductive portion is nonoverlapping with any other exposed conductive portion. A patterned electrode layer is coated on at least a portion of the stack and defines one or more electrodes. Each electrode of the one or more electrodes in electrical contact with an exclusive subset of the exposed conductive portions. The functional layers can be passive conductors forming capacitors, resistors, inductors, or antennas, or active layers forming electronic circuits.

    Abstract: A monolithic multi-FET transistor comprises an epitaxial layer disposed on a dielectric layer. The epitaxial layer comprises a crystalline semiconductor material and a multi-FET area. An isolation structure surrounds the multi-FET area and divides the multi-FET area into separate FET portions. A gate disposed on a gate dielectric extends over each FET portion. A source and a drain are each disposed on opposite sides of the gate on the epitaxial layer within each FET portion. Each gate, source, and drain comprise a separate electrical conductor and the gate, source, drain, and epitaxial layer within each FET portion form a field-effect transistor. Gate, source, and drain contacts electrically connect the gates, sources, and drains of the separate FET portions, respectively. At least the sources or drains of two neighboring FET portions are disposed in common over at least a portion of the isolation structure dividing the two neighboring FET portions.

    Abstract: A hybrid document includes a flexible document having visible markings. One or more light-controlling elements and a controller are embedded in or on the flexible document. The controller is electrically connected to the one or more light-controlling elements to control the one or more light-controlling elements. A power input connection is electrically connected to the controller, or one or more light-controlling elements, or both. A power source can be connected to the power input connection, for example a piezoelectric or photovoltaic power source. In response to applied power, the controller causes the one or more light-controlling elements to emit light. In some embodiments, the controller includes a memory and a value can be stored in the memory and displayed by the light-controlling element(s). In some embodiments, the value can be assigned or varied by a hybrid currency teller machine.

    Abstract: An example of a cavity structure comprises a cavity substrate comprising a substrate surface, a cavity extending into the cavity substrate, the cavity having a cavity bottom and cavity walls, and a cap disposed on a side of the cavity opposite the cavity bottom. The cavity substrate, the cap, and the one or more cavity walls form a cavity enclosing a volume. A component can be disposed in the cavity and can extend above the substrate surface. The component can be a piezoelectric or a MEMS device. The cap can have a tophat configuration. The cavity structure can be micro-transfer printed from a source wafer to a destination substrate.

    Abstract: An example of a method of making a printed structure comprises providing a destination substrate, contact pads disposed on the destination substrate, and a layer of adhesive disposed on the destination substrate. A stamp with a component adhered to the stamp is provided. The component comprises a stamp side in contact with the stamp and a post side opposite the stamp side, a circuit, and connection posts extending from the post side. Each of the connection posts is electrically connected to the circuit. The component is pressed into contact with the adhesive layer to adhere the component to the destination substrate and to form a printed structure having a volume defined between the component and the destination substrate. The stamp is removed and the printed structure is processed to fill or reduce the volume.

    Abstract: A hybrid currency banknote includes a banknote having visible markings. One or more light-controlling elements and a controller are embedded in or on the banknote. The controller is electrically connected to the one or more light-controlling elements to control the one or more light-controlling elements. A power input connection is electrically connected to the controller, or one or more light-controlling elements, or both. A power source can be connected to the power input connection, for example a piezoelectric or photovoltaic power source. In response to applied power, the controller causes the one or more light-controlling elements to emit light. A value can be stored in a memory in the controller and displayed by the light-controlling elements. The value can be assigned or varied by a hybrid currency teller machine.
