A device for manufacturing a stretchable substrate structure according to an embodiment includes a carrier substrate receiving portion configured to receive a carrier substrate therein, a stretchable substrate receiving portion configured to receive a stretchable substrate in a direction facing the carrier substrate, and a diaphragm configured to be deformed by air pressure provided on one surface, wherein the diaphragm comes in contact with an entire surface of the stretchable substrate in a plane direction when deformed, such that the stretchable substrate is combined to the carrier substrate by deforming according to the deformed shape of the diaphragm.

Provided is a device in which the metal content existing in a joining interface is controlled. A manufacturing method for the device comprises: a step in which the surfaces of a first substrate and a second substrate are activated using a FAB gun; a step in which a plurality of metals are discharged by using the FAB gun to sputter a discharged metal body comprising the plurality of metals, and the plurality of metals are affixed to the surfaces of the first substrate and the second substrate; a step in which the first substrate and the second substrate are joined at room temperature; and a step in which heating is performed at a temperature that is high in comparison to the agglomeration start temperature of the plurality of metals and of the elements that constitute the first substrate or the second substrate. With regards to the step in which the plurality of metals are affixed, the density of the plurality of metals existing on the joining interface of the first substrate and the second substrate is set to 1×10.sup.12/cm.sup.2 or less by adjusting the exposure area of the discharged metal body.

According to the invention there is provided a component including a supercapacitor and a method of producing same. The component comprises a first (12) and second (14) electrode and a separator structure (16) which separates the two electrodes and contains a liquid or gel electrolyte. The first and second electrode structures are each formed from a composite material (10) which includes electrically conductive fibers and electrochemically active material in a binder matrix and the supercapacitor is formed to be structurally inseparable from the rest of the component. Further, the component forms a structural capacitor. The obtained structural capacitor could be used in aircraft structure to save weight.

In an illustrative implementation of this invention, a 3D object comprises substrate layers infiltrated by a hardened material. The 3D object is fabricated by a method comprising the following steps: Position powder on all or part of a substrate layer. Repeat this step for the remaining substrate layers. Transform the powder into a substance that flows and subsequently hardens into the hardened material. The hardened material solidifies in a spatial pattern that infiltrates positive regions in the substrate layers and does not infiltrate negative regions in the substrate layers.

The disclosure relates to laminate structures to cover or protect substrates or surfaces. The laminate structure comprises a support layer and a self-sterilizing/antimicrobial layer comprising a sulfonated polymer, capable of killing microbes within minutes and for an extended period of time. The sulfonated polymer has a sufficient degree of sulfonation to kill in less than 120 minutes at least 90% of microbes in contact with the surfaces, and for extended protection of the surfaces for at least one month. The laminate structure is particularly suitable for protecting high-touch surfaces such as door knobs, touch-screens, tables, as well as for use with facemasks, face shields, or as self-sterilizing wraps for surgical instruments and supplies. The laminates can also be used as garments or to cover/protect personnel having contagious diseases, etc., to decrease the transmission of microbes.
