Art and Sensors – Via Emotions to the Product
Students at the Bauhaus University in Weimar were looking at alternative ways of marketing the results of high-tech research. The collaboration between the university and the CiS Research Institute for Microsensors and Photovoltaics came about as part of an interdisciplinary “prototype seminar” held by the Chair of Media Management. The aim of the seminar was to find new, generally comprehensible and attractive ways of accessing the application possibilities of high-tech solutions in need of explanation
Better vision with intelligent implant – micro-optical accommodation system as an alternative to intraocular lenses
The decreasing accommodation ability of the eye with increasing age (presbyopia) can be compensated by visual aids. In case of additional lens opacity (cataract), the removal of the lens and the implantation of an intraocular lens (IOL) are necessary. The new approach to solve this problem pursued in the BMBF-funded project “Akkosys” is a smart microsystem that is implanted in the capsular bag of the eye instead of an intraocular lens
Optoflutronics – Microfluidic Fluorescence and Absorption Sensor
CiS Research Institute leads the development of a micro-fluorescence sensor. In a multi-channel sensor the optical excitation with different light wavelengths and the measurement of transmission and fluorescence signals take place
With innovations from Thuringia – Radiation-hard silicon detectors in the search for the Higgs boson
Thuringia is significantly involved in the discovery of the Higgs elementary particle. Scientists and engineers of the CiS Forschungsinstitut für Mikrosensorik und Photovoltaik GmbH are working in Erfurt on radiation-hard silicon detectors for the international nuclear research elite at CERN (Geneva). The CiS Research Institute is proud to have contributed decisively to the success with its achievements and congratulates the colleagues in Switzerland
Force sensor for haptic assistance systems in medicine
A miniaturized force sensor measures the forces at catheter tips that occur between the guide wire (catheter) and blood vessels during insertion. The KASYS mini-chip, just 200 x 220 x 640 µm in size and thus just twice as wide as a hair, is the heart of a haptic assistance system that will simplify catheterizations in medicine in the future and reduce the risk of injury
Non-contact, interferometric distance measurement
Technologies from microsystems engineering and microoptics form the basis for the successful miniaturization of a new, interferometric distance measurement system from TETRA GmbH in Ilmenau. The core component, consisting of a Michelsen laser interferometer and an optical silicon detector, was developed by the mechatronics specialist together with the Microoptical Systems Application Center at CiS Research Institute
Interferometric pressure sensor
Using MEMS wafer technologies and a silicon photodiode array with embedded laser light source (naked VCSEL), the CiS Research Institute has succeeded in integrating the complete optical sensing of the pressure-sensitive, membrane (Silizum) in a very flat package space – comparable to capacitive or piezoresistive sensors
3D silicon photodiode with PigTail
The 3D structuring of silicon is becoming increasingly important for optical and opto-electronic applications in microsystems technology. For the reliable and low-loss coupling of optical fibers to photodiodes, the CiS Research Institute developed new microstructuring technologies for the fabrication of cavities with flank angles of 45° and 90° and high optical absorption of the sensitive coupling surface
Power from light – fieldbus-compatible sensors for extreme operating conditions
For the use of sensor systems under extreme conditions, such as in EMC-critical or Ex-protected areas, a galvanic connection of the sensors for energy supply or signal transmission is often not possible. Together with industrial partners, the application center microoptical systems of the CiS research institute developed a solution compatible with existing fieldbus systems
ToMess multi-sensor module
Microstructured reactors have been successfully finding their way into the laboratories and production facilities of large-scale and fine chemistry as well as medicine for several years. Worldwide research activities impressively show that the use of the micro-process engineering components can achieve a multitude of reaction engineering advantages in chemical processes
