  • Publication number: 20180205089
    Abstract: A method of manufacturing a Lithium battery (100) with a current collector formed of pillars (11) on a substrate face (10), wherein the method comprises: forming elongate and aligned structures forming electrically conductive pillars (11) on the substrate face (10) with upstanding pillar walls extending from a pillar base to a pillar top; wherein the pillars are covered with a laminate comprising a first electrode (12), a solid state electrolyte layer (13); a second electrode layer (14), and a topstrate (20) forming an electrode part; and wherein at least one of the first electrode layer, second electrode layer and topstrate layer is non-conformally coated to prevent Lithium intercalation into the first or second electrode near the pillar base by limiting cracking at the pillar base when volume expansion/contraction of the electrode layers happens during the battery charge/discharge cycles.

  • Publication number: 20180159133
    Abstract: An method for manufacturing a electronic device is provided having a current collector capable of a high specific charge collecting area and power, but is also achieved using a simple and fast technique and resulting in a robust design that may be flexed and can be manufactured in large scale processing. To this end the electronic device comprising an electronic circuit equipped with a current collector formed by a metal substrate having a face forming a high-aspect ratio structure of pillars having an interdistance larger than 600 nm. By forming the high-aspect structure in a metal substrate, new structures can be formed that are conformal to curvature of a macroform or that can be coiled or wound and have a robust design.

  • Publication number: 20180015501
    Abstract: A coating system (1) is provided comprising a coating chamber (20) having arranged therein a coating apparatus (10) for providing a substrate (S) with an organic coating layer. The coating apparatus (10) comprises a coating device (12) for depositing a solvent free, curable liquid organic precursor for said organic coating layer and a curing unit (14) for curing the liquid organic precursor deposited on said substrate (S) by supplying energy to said liquid organic precursor. The coating system further comprises a vacuum pump (30) that, while coating, maintains a pressure inside said coating chamber below 1 mbar. A supply facility (152, 152?) for controllably supplies the curable liquid organic precursor from the reservoir to the coating device (12), The supply facility (152, 52?) has an input (1510) for receiving curable liquid organic precursor from the reservoir. A position of a bottom (150B) of the reservoir is arranged at a height (H1) above the input (1510).

  • Publication number: 20170317356
    Abstract: A system and method for manufacturing a micropillar array (20). A carrier (11) is provided with a layer of metal ink (20i). A high energy light source (14) irradiates the metal ink (20i) via a mask (13) between the carrier (11) and the light source. The mask is configured to pass a cross-section illuminated image of the micropillar array onto the metal ink (20i), thereby causing a patterned sintering of the metal ink (20i) to form a first subsection layer (21) of the micropillar array (20) in the layer of metal ink (20i). A further layer of the metal ink (20i) is applied on top of the first subsection layer (21) of the micropillar array (20) and irradiated via the mask (13) to form a second subsection layer (21) of the micropillar array on top. The process is repeated to achieve high aspect ratio micropillars 20p.

  • Publication number: 20150374920
    Abstract: A device and method is provided for drug supply. The device comprises a holder suitable for holding a carrier comprising a drug layer (151); a transmission part for transmitting a laser beam from a laser system, via the transmission part to the carrier; a placement provision; arranged for distancing the carrier from the skin or tissue; and a control mechanism. The control mechanism is arranged to moving a laser beam and/or the carrier relative to each other, in order to provide a virginal area of the carrier for the laser beam; and impinging the laser beam via the transmission part on the carrier; in such a way that the carrier is activated to eject a distinct quantity of drug transferred (50) in normal direction from the carrier from the drug layer into the skin or tissue. Accordingly drugs can be injected in a controlled way without using nozzles or needles.

  • Publication number: 20150200370
    Abstract: A method and system are provided for dividing a continuous barrier foil into a barrier foil segment that may be cut without exposing an organic layer in the barrier foil segment. A groove is formed alongside a perimeter of the barrier foil segment. The groove extends through the organic layer and is sealed by a sealing material to form a sealed groove. The sealed groove may prevent moisture and/or oxygen from reaching organic material in the barrier foil segment when it is cut. A sealed barrier foil segment is thus provided.
