  • 11.04.2019 Smart acoustic sensing based on artificial hair cells

    The goal of this project is to build a smart sensing system for sound detection which is capable of information processing and (self-) adaption to the current environment. The underlying principles are inspired by the sound detection in the (human) inner ear, the cochlea.

  • 01.03.2019 Development and application of new forward solutions in Lorentz force eddy current testing

    The detection and evaluation of defects in solid conductive materials is important in quality assurance. Non-destructive testing is a quality control tool widely used in the metal industry for inspecting electrically conductive materials. One of the most extensively used techniques in the non-destructive testing inspection is the eddy current testing. Here, an alternating current produces a time-varying magnetic flux density, which according to the Faraday's electromagnetic induction, induces currents in an electrical conductor. Variations in electrical conductivity inside an object under test or the presence of defects cause changes in eddy currents and consequently a change in the impedance of the coil. Measuring this impedance, a defect can be detected. However, due to the skin effect, eddy current testing is limited to surface cracks and cracks close to the surface.

  • 07.02.2019 Successful funding programme for young women scientists

    There are not enough female professors. What can be done about the fact that so many leave the universities after their doctorates? Do scholarships help to keep more women in science? In 2018, five young ladies were awarded scholarships under the programme for promoting young female scientists at Technische Universität Ilmenau. The funding was provided by the Thuringian Ministry for Economic Affairs, Science and Digital Society (TMWWDG) and TU Ilmenau.

  • 04.09.2018 Precise calibration system for micro- and nano-force sensors

    Over the past 15 years the Raster-Kraft-Mikroskopie (atomic force microscopy) has developed into a standard analytical method in micro- and nanosystems technology and contributes significantly to the rapid development in nanotechnology. It allows microscopic images in an enlargement of several million times and thus the visualization of yet undiscovered details. The centerpiece of the atomic force microscope is the cantilever, consisting of a measuring tip which is located with at a length of 100… 400 μm at the end of a flexible cantilever. When the spring stiffness of such a cantilever is calibrated, i.e. its force-deflection-characteristic, it can also be used for measuring the smallest forces on a microscopic scale.[more]

  • 30.07.2018 Cross-National Research on Online Sexuality

    Sexuality is an important part of human life and is closely linked to health, life satisfaction and the quality of relationships. The sexual culture in Germany has undergone two crucial changes in the past fifty years: The so-called sexual revolution of the 1960s brought about a surge of liberalization, especially through the contraceptive pill and the reform of criminal law at the time. Since then, for example, the consumption of pornography and the cohabitation of unmarried couples have been legal. [more]

  • 08.06.2018 Research Project Flora Incognita – Interactive Plant Species Identification with Smartphones

    Biodiversity is constantly changing. Globalization, climatic changes, as well as regional landscaping are continuously affecting our natural ecosystem. Declining population numbers of plant species native to the Federal Republic of Germany can thus be observed as well as the immigration and settlement of invasive plant species.[more]

  • 04.06.2018 Research Training Group tip- and laser- based 3D-Nanofabrication in extended macroscopic work areas (NanoFab)

    For 40 years now the semiconductor industry has been following Moore’s Law with astonishing consistency. Despite far-reaching further developments in optical lithography, it is becoming evident that structure sizes of < 20 nm can only be achieved with great effort using known methods. Meanwhile, the fundamental challenge is in the development of alternative production technologies particularly for micro- and nanotechnologies which can measure and work on the atomic scale in steadily increasing work areas of several hundred millimeters in diameter.
