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 to example, to a pressure change in an addressed reservoir caused by displacement of the compliant membrane or other actuation element.

Abstract:
The invention relates to a method for producing a three-dimensional structure. The method according to the invention comprises the following steps: applying to or introducing into a carrier element (1; 7; 16) particles (2), a plurality of at least partially interlinked cavities being formed between the particles (2) and the particles (2) coming into contact in points of contact, and interconnecting the particles (2) in the points of contact by coating the system consisting of particles and the carrier element, the coat (4) produced during coating penetrating the cavities at least to some extent. The method according to the invention allows the production of three-dimensional structures with little effort.
Abstract:
A component comprising a carrier, a chip component and a MEMS component is proposed, wherein the mechanically sensitive MEMS component is mounted below a half-shell on the carrier. The component is encapsulated with a molding compound in a transfer molding process.
Abstract:
The invention relates to a method for making a 3D nanostructure having a nanosubstructure, comprising the steps of: i) providing a mold comprising at least one sharp concave corner; ii) conformational depositing at least one structural material in the sharp concave corner; iii) isotropically removing structural material; iv) depositing at least one other structural material; v) removing earlier deposited structural material; vi) forming a nanosubstructure; and vii) removing the mold thereby providing the 3D nanostructure having the nanosubstructure.
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.
Abstract:
A process is disclosed for producing metal-based, high-aspect-ratio microscale structures (HARMs), for example microchannels in a heat exchanger. The preferred manufacturing method operates in a continuous mode, and employs low-temperature rolling of metals. A process is disclosed for bonding metal microchannel sheets or plates to flat metal sheets or plates to form single-, double-, and multiple-layered microchannel structures. The process can operate at much lower temperatures than prior methods of compression microscale molding of metals, at room temperature or even lower.

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.
