A simple, feasible method for the production of laminate composites, consisting of a perforated substrate and a polymer membrane, now allows for the production of tactile displays the size of a computer screen. The procedure developed at Furtwangen University now enables the coating of large substrates with a high-quality membrane film, without creating air bubbles at the bond interface. The new method is environmentally-friendly, as the carrier is reusable and no chemicals are required to reduce adhesion. The procedure can be integrated into commercially available lamination systems.

When a foreign substance invades a body, the body produces antibodies that recognise and fight the intruder by means of antibodies that bind to a specific…
Here we offer a technology that allows formation of III-V-material vertical nanowire lasers grown directly on a silicon wafer as a substrate. This opens the door to CMOS-conform production of telecom-lasers as well as new logical chip architectures.
Fatigue tests can be implemented for stents in different forms and fabrics, even grafts and drug eluting stents. The device is working at 20 kHz and can generate up to 50.000 load cycles per second. Test time is reduced from weeks to hours.
The invention provides a surgical tool, which generates a precise, pre-defined cut surface so that a good fit between the contact surfaces of the prosthesis and the bone is ensured.
The removal is affected by the use of a tool that has a vibrating unit and a holding part, which is important for directing to the bone.
There is an oscillating stroke movement along an axis parallel to the mounting direction of the joint prosthesis, as well as rotational movement about the same axis. The moving tool head has lying surfaces at an angle to one another, which are then adapted to the contact surfaces of joint prostheses. In order to produce defined-sectional areas, the holding part is fixed in the bone intramedullary, to ensure a guide of the surgical tool with fastening elements.
