摘要:
A method for manufacturing an at least partially porous, hollow silicon body, including the steps of vertical, anisotropic etching, porosifying, and electropolishing. Hollow silicon bodies manufactured using this method; the body wall including an inner layer, an intermediate layer, and an outer layer, and the porosity of the intermediate layer being greater than those of the inner and outer layers. The use of the hollow silicon bodies.
摘要:
A method for producing porous microneedles (10) situated in an array on a silicon substrate includes: providing a silicon substrate, applying a first etching mask, patterning microneedles using a DRIE process (“deep reactive ion etching”), removing the first etching mask, at least partially porosifying the Si substrate, the porosification beginning on the front side of the Si substrate and a porous reservoir being formed.

摘要:
A method and a device for treating a material having nanoscale pores), especially implant material for the treatment of living cells, as provided. The method distinguished in that the surface tension of a substance (10) provided for filling the volumes of the nanoscale pores (9) is reduced. The present invention also includes a device for carrying out this method.
摘要:
An array for placement on the skin of a human or animal patient for the purpose of the transdermal application of pharmaceuticals, toxins or active agents, having microneedles that are situated on a carrier substrate, the microneedles having a preset breaking point in the area of the transition to the carrier substrate.
摘要:
A device for storing and transporting microneedles and a method for delivering active substances with the aid of such a device. In the device for storing and transporting microneedles, a reservoir is provided which contains an active substance for delivery by the microneedles and the microneedles are situated within a package forming the reservoir.
摘要:
An apparatus for noninvasive blood pressure measurement having a device for measuring blood pressure values and an acceleration sensor, in particular a two- or three-axis acceleration sensor for measuring movements is provided for measuring and monitoring blood pressure. Using the movement data ascertained by the acceleration sensor, movement artifacts are calculated out of the measured blood pressure values with the aid of a signal processing system.

摘要:
A microfluidic component having at least one first polymer layer, which is provided with a microstructure for at least one fluid, and having at least one second polymer layer. It is provided that at least one semiconductor component is situated on the first and/or the second polymer layer. Furthermore, a manufacturing method for such a microfluidic component is described.
摘要:
In the manufacture of at least one passage in a silicon wafer, in a first method step, starting from a first side of the wafer, a first recess is produced in the wafer, and in a second method step, starting from a second side of the wafer, a second recess is produced in the wafer. The first recess and the second recess are produced such that together they form a passage between the first and second sides of the silicon wafer.
