Abstract: 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.

Abstract: The invention relates to a device for the IR-spectrometric analysis of a solid, liquid or gaseous medium. The device includes a process probe, which has a reflection element. The device additionally includes a linear variable filter, at least one detector element, and a control/evaluation unit. At least one light source is also provided, the light of which is coupled into the reflection element via a collimating optics. At least one optical waveguide having a light input section and a light output section is provided. The light is guided via the light output section of the optical waveguide into a defined region of the linear variable filter. The detector element and the linear variable filter are arranged movably relative to one another over approximately the length of the linear variable filter. The control/evaluation unit determines the spectrum of the medium on the basis of the measured values delivered from the detector element.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A biochip for electrical, e.g., capacitive, detection of biochemical molecules has an electrode array on a substrate, the electrodes of the electrode array being each connected through the substrate to an electrically conductive contact surface via an electrical conductor. The contact surfaces are situated on the side of the substrate facing away from the electrode array and form the outermost plane of the substrate on this side.
