Sensor

A sensor is a device that detects and responds to some type of input from the physical environment. The specific input could be light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena. The output is generally a signal that is converted to human-readable display at the sensor location or transmitted electronically over a network for reading or further processing.

    Miniaturized connected systems and outstanding business contacts: forming networks on both technical and business level was one of the key features of COMPAMED 2016, the international trade fair for suppliers and manufacturers of medical technologies. This trend was visible at and enhanced by the joint trade fair booth of the IVAM Microtechnology Network in hall 8a, the accompanying presentation forum and numerous B2B meetings between companies from Germany and Japan.

    Computer sind ein wichtiges Werkzeug im Alltag, sei es als PC oder als Smartphone. In Zukunft werden sie zunehmend mit den Alltagsgegenständen verschmelzen und von dort aus den Nutzer unterstützen, etwa als Smartwatch, Displaybrillen, Sensorkleidung und vieles mehr. Über diesen Trend der Digitalisierung tauschen sich Wissenschaftler, Unternehmer, Modedesigner und Nutzer auf der vom KIT mitorganisierten Konferenz ISWC/UBICOMP vom 12. bis 16. September 2016 in Heidelberg aus. Vertreter der Medien sind herzlich eingeladen. Anmeldung bitte mit beigefügtem Formular oder per E-Mail.

  • Countdown to the space mission “Solar Orbiter”: Measuring instruments from Kiel start their voyage

    Around five years ago, a team led by a physicist from Kiel University, Professor Robert Wimmer-Schweingruber, won the coveted tender for providing instruments to be placed on board the “Solar Orbiter” space probe. This joint mission of the European Space Agency (ESA) and the US space agency NASA is expected to launch in October 2018, and will go closer to the sun than has ever been done before. Now, exactly on schedule, the preparations in Kiel for this mission are entering their final phase. On Monday 21 November the flight instruments from Kiel will be handed over to the space probe installation team in England.

  • Effect of humidity on graphene sensors demistified

    Humidity effect on graphene doping.

    Graphene produced with chemical vapor deposition (CVD) will form the cornerstone of future graphene-based chemical, biological, and other types of sensors. Graphene, however, is extremely sensitive to air, in particular to humidity. To avoid unwanted background coming from humidity and to calibrate future sensors, it is highly important to investigate the mechanisms by which water (in the form of environmental humidity) affects graphene sheets.

    Die Doppelhelix hat als stabile und flexible Struktur des Erbguts das Leben auf der Erde erst möglich gemacht. Nun hat ein Team der Technischen Universität München (TUM) eine Doppelhelix-Struktur auch in einem anorganischen Material entdeckt. Das Material aus Zinn, Iod und Phosphor ist ein Halbleiter, besitzt außergewöhnliche optische und elektronische Eigenschaften und ist mechanisch hoch flexibel.

  • Launch of New Industry Working Group for Process Control in Laser Material Processing

    At AKL’16, the International Laser Technology Congress held in May this year, interest in the topic of process control was greater than expected. Appropriately, the event was also used to launch the Industry Working Group for Process Control in Laser Material Processing. The group provides a forum for representatives from industry and research to initiate pre-competitive projects and discuss issues such as standards, potential cost savings and feasibility. In the age of industry 4.0, laser technology is firmly established within manufacturing. A wide variety of laser techniques – from USP ablation and additive manufacturing to laser polishing – are now commonplace in large-scale production.

  • Manipulation of the characteristics of magnetic materials

    In the simulation, magnetic signals spread along the domain walls in a few nanoseconds. The signals behave in a wave-like manner, with the initially high amplitude rapidly becoming smaller. McCord

    Magnets are not everywhere equally magnetized, but automatically split up into smaller areas, so-called magnetic domains. The walls between the domains are of particular importance: they determine the magnetic properties of the material. A research team of material scientists from Kiel University is working on artificially creating domain walls to be able to modify in a controlled way the behaviour of magnets on a nanometre scale. In the long term, this method could also be used for high-speed and energy-efficient data transfer. The research results were recently published in the renowned journal “Scientific Reports”.

    Researchers from Freiburg have developed a sensor platform that quantifies antibiotics in human blood within minutes. A team of researchers from the University of Freiburg has developed a system inspired by biology that can detect several different antibiotics in human blood or other fluids at the same time. This biosensor system could be used for medical diagnostics in the future, especially for point-of-care testing in doctors’ practices, on house calls and in pharmacies, as well as in environmental and food safety testing. The researchers focused their study on the antibiotics tetracycline and streptogramin in human blood.

    Der Datenverkehr wächst weltweit. Glasfaserkabel transportieren die Informationen mit Lichtgeschwindigkeit über weite Entfernungen. An ihrem Ziel müssen die optischen Signale jedoch in elektrische Signale gewandelt werden, um im Computer verarbeitet zu werden. Forscher am KIT haben einen neuartigen Photodetektor entwickelt, dessen geringer Platzbedarf neue Maßstäbe setzt: Das Bauteil weist eine Grundfläche von weniger als einem Millionstel Quadratmillimeter auf, ohne die Datenübertragungsrate zu beeinträchtigen, wie sie im Fachmagazin Optica nun berichten.
