Abstract
We present a novel simple and efficient method for the full removal of the influence of ambient temperature variations to the operation of bimaterial-based MEMS actuators and sensors. The removal of the undesired interference is achieved through the very structure of the bimaterial cantilever, by reversing the order of bimaterial constituent materials at a certain length. Thus an extremely simple geometry is obtained for full self-compensation of the structures. We performed the full simulation of our devices by the finite element method. The structures require standard surface micromachining and utilize only Si-technology compatible materials like polyimides or SU-8. A simple rule for the determination of the zero-deflection condition is presented. The described compensation method enables a significantly reduced bimaterial device area and a much higher packaging density in element arrays, as well as an improved signal-to-noise ratio. The method is especially convenient for photodetector arrays for direct conversion of infrared radiation spatial distribution into a visible image.
Feasibility study for microfluidic separation device for biological fluids
Imego AB
18
Denator AB
Yes
The study requested is a preparation for a possible research and development project of a product that can perform fast separation and inactivation of biological fluids. Proteins, peptides and metabolites are rapidly degraded after extraction, which causes large problems for both academic and industrial protein research. In this study, Imego will investigate the feasibility of fabricating low-cost glass and polymer chips that combine microfluidic separation with Denator’s proprietary preservation technology.

The Institute for Microsystem Technology (IMTEK), founded in 1995, is one of the largest academic institutions in this field. As it was created completely from scratch as part of the new-founded Faculty of Applied Sciences we share a new campus with modern teaching and training facilities together with the Institute of Computer Science. The foundation of a new technical faculty provided the chance not only to use new facilities but also to create a novel engineering course which differs significantly from traditional engineering disciplines. So the basis for the specification of the course has been the questions for the indispensable skills of a ‘universal’ engineer of the 21st century. The curriculum was inaugurated in October 1996 when the first classes started in the course microsystem technology. The first graduations have been in spring 2001. Between 1998 and 2001 about 90 freshmen started studying Microsystem Technology every year. The curriculum has been modified several times since 1996 in order to comply more and more with our initial goals.
