    Author : Federico Ribet; Niclas Roxhed; Göran Stemme; Boris Stoeber; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microelectromechanical systems MEMS ; biosensors; biomedical devices; continuous glucose monitoring CGM ; glucose sensors; microneedles; interstitial fluid sampling; minimally-invasive technologies; electrochemical sensors; heterogeneous integration; wire bonding; magnetic assembly; electrowetting-on-dielectric EWOD ; digital microfluidics; ionic liquids; gas sensors; optical switches; laser shutters.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Interdisciplinary research between medicine and microsystem engineering creates new possibilities to improve the quality of life of patients or to further enhance the performance of already existing devices. In particular, microsystems show great potential for the realization of biosensors and sampling devices to monitor bioanalytes with minimal patient discomfort. READ MORE

  2. 2. Nanomechanical Studies and Applications of Cantilever Sensors

    Author : Sara Ghatnekar-Nilsson; Fasta tillståndets fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; resonating; mass sensor; Young s modulus; CMOS; cantilevers; electron beam lithography; liquid;

    Abstract : Different aspects of cantilevers to be used as sensors have been studied. Silicon cantilevers have been fabricated and integrated on CMOS chips using low-energy electron beam lithography in order to reduce the irradiation damage to the circuits. The released and integrated cantilevers have been tested and used as mass sensors in air. READ MORE

  3. 3. On the Frequency and Q Factor Response of the Quartz Crystal Microbalance to Liquid Overlayers

    Author : Michael Rodahl; Chalmers University of Technology; []
    Keywords : piezoelectric effect; solid-liquid interface; sensors; protein adsorption; QCM; tribology; quartz crystal microbalance;

    Abstract : The quartz crystal microbalance (QCM) is an ultra-sensitive weighing device. It consists of a piezoelectric quartz crystal, often in the form of a disk, which is sandwiched between a pair of evaporated electrodes. READ MORE

  4. 4. Non-covalent Modification of Graphene and MoS2 Synthesis and Characterization of Charged Molecules and Two-Dimensional Materials

    Author : Steffen Brülls; Chalmers University of Technology; []
    Keywords : sensors.; molybdenum disulfide; intermolecular interactions; charged π-conjugated systems; doping; non-covalent interactions; functionalization; cation; Graphene; anion;

    Abstract : Graphene is a material of superlatives. It has unique properties, which are explored in various areas of interdisciplinary research. Graphene can improve the properties of other materials or even give them new functions and is therefore a suitable candidate for different sensor applications. READ MORE

  5. 5. On the On-line Tools for Treatment of Deterioration in Industrial Processes
