  2. 1. Integrated microsystems for continuous glucose monitoring, interstitial fluid sampling and digital microfluidics

    Author : Federico Ribet; Niclas Roxhed; Göran Stemme; Boris Stoeber; KTH; []
    Keywords : 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

  4. 2. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

    Author : Peter Tobias; Ignaz Eisele; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

    Abstract : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

  5. 3. Nanomechanical Studies and Applications of Cantilever Sensors

    Author : Sara Ghatnekar-Nilsson; Fasta tillståndets fysik; []
    Keywords : 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

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

    Author : Michael Rodahl; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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

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

    Author : Steffen Brülls; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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
