Abstract:
A flexible patch pump for controllable accurate subcutaneous delivery of one or more medicaments to a patient includes a laminated layered structure. The pump may have a rigid reservoir layer including a number of rigid reservoirs disposed in a flexible material; a flexible microfluidic layer including a compliant membrane for sealing the rigid reservoirs, a network of microfluidic channels connecting the rigid reservoirs, and a number of inlet and/or outlet valves corresponding to the rigid reservoirs; and a flexible-rigid electronic circuit layer including a number of individually-addressable actuators. In operation, the rigid reservoirs may contain medicament that is dispensed in precise volumes at appropriate times due, for example, to a pressure change in an addressed reservoir caused by displacement of the compliant membrane or other actuation element.
Abstract:
Disclosed is a method for manufacturing a microcantilever having a predetermined thickness that includes forming a liquid synthetic resin for cantilevers to a thickness corresponding to the thickness of the microcantilever on an upper surface of a base block having an adhesive base and a non-adhesive base, and curing the liquid synthetic resin for cantilevers via a boundary between the adhesive base and the non-adhesive base, wherein the adhesive base has stronger adhesivity to the cured synthetic resin for cantilevers than the non-adhesive base.
Abstract:
A photovoltaic device includes an electron accepting material and an electron donating material. One of the electron accepting or donating materials is configured and dimensioned as a first component of a bulk heterojunction with a predetermined array of first structures, each first structure is substantially equivalent in three dimensional shape, has a substantially equivalent cross-sectional dimension, and where each first structure of the array of first structures has a substantially equivalent orientation with respect to adjacent first structures of the predetermined array forming a substantially uniform array.
Abstract:
This invention relates to a method of fabricating a three-dimensional copper nanostructure, including manufacturing a specimen configured to include a SiO2 mask; performing multi-directional slanted plasma etching to form a three-dimensional etching structure layer on the specimen; performing plating so that a multi-directional slanted plasma etched portion of the specimen is filled with a metal; removing an over-plated portion and the SiO2 mask from the metal layer; and removing a portion of a surface of the specimen other than the metal which is the three-dimensional etching structure layer. In this invention, a uniform copper nanostructure array can be obtained by subjecting a large-area specimen disposed in a Faraday cage to multi-directional slanted plasma etching using high-density plasma, forming a copper film on the etched portion of the specimen, and removing an over-plated copper film and the SiO2 mask, and the diameter of the copper nanostructure can be arbitrarily adjusted, thus attaining high applicability.
Abstract:
The invention relates to a method of forming a microfluidic array comprising at least one channel of semi-circular section, comprising the following steps: bringing into contact a first liquid (7) with an array of electrodes (3) of a microfluidic chip (1) comprising at least one pair of substantially parallel and coplanar electrodes (3a, 3b) arranged on a substrate (4), activating said array of electrodes so as to actuate by liquid dielectrophoresis LDEP said first liquid to form a fluidic structure (9) comprising at least one fluidic finger (9a), and using said fluidic structure as a mould to form said microfluidic array by solidification or hardening of a second liquid (11) deposited on the microfluidic chip and hugging the shape of said fluidic structure.
Abstract:
A dry adhesive and a method of forming a dry adhesive. The method includes forming an opening through an etch layer and to a barrier layer, expanding the opening in the etch layer at the barrier layer, filling the opening with a material, removing the barrier layer from the material in the opening, and removing the etch layer from the material in the opening.
Abstract:
A device is made by forming sacrificial fibers on a substrate mold. The fibers and mold are covered with a first material. The substrate mold is removed, and the covered fibers are then removed to form channels in the first material.
Abstract:
Layered nanostructures are constructed by imprinting material with a mold, while selectively modifying and removing a portion of the mold. The mold, which includes a pattern of features, is modified so that the portion of the mold that includes the features is made chemically and/or physically distinct from the rest of the mold. That portion of the mold that includes the features is retained while the rest of the mold is removed. The retained portion of the mold provides mechanical support for any adjoining layer or layers.
Abstract:
A method of fabricating an elastomeric structure, comprising: forming a first elastomeric layer on top of a first micromachined mold, the first micromachined mold having a first raised protrusion which forms a first recess extending along a bottom surface of the first elastomeric layer; forming a second elastomeric layer on top of a second micromachined mold, the second micromachined mold having a second raised protrusion which forms a second recess extending along a bottom surface of the second elastomeric layer; bonding the bottom surface of the second elastomeric layer onto a top surface of the first elastomeric layer such that a control channel forms in the second recess between the first and second elastomeric layers; and positioning the first elastomeric layer on top of a planar substrate such that a flow channel forms in the first recess between the first elastomeric layer and the planar substrate.
