2. 6. Electroosmotic pumps with electrochemically active electrodes

   Author : Per Erlandsson; Nathaniel D Robinson; Mats Fahlman; Adrienne Minerick; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Electrokinetic phenomena, motion caused by an applied electric field, can be used to separate molecules based on charge as in capillary electrophoresis, or pump liquids with electroosmosis. As microfluidic devices are becoming more advanced, involving multiple stages (sequential reactions) and requiring smaller amounts of reagent, the demand for precise fluid control and integrated electrodes increases.

4. 7. Sensor-Based Garments that Enable the Use of Bioimpedance Technology : Towards PersonalizedHealthcare Monitoring

   Author : Juan Carlos Marquez Ruiz; Kaj Lindecrantz; Fernando Seoane; Ramon Bragós Bardia; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioimpedance; textrodes; textile electrodes; Impedance Cardiography; Body Composition;

   Abstract : Functional garments for physiological sensing purposes have been utilized in several disciplinesi.e. sports, firefighting, military and medical. In most of the cases textile electrodes (Textrodes)embedded in the garment are employed to monitor vital signs and other physiologicalmeasurements. READ MORE

5. 8. Components of smart windows : Investigations of electrochromic films, transparent counter electrodes and sputtering techniques

   Author : Lisen Kullman; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

   Abstract : In smart windows, the transmittance of visible and near infrared radiation can be reversibly and persistently modulatcd by an applied voltage pulse (~2 V). The micrometer-thick multi-layer structure contains two electrodes capable of charge insertion. One of these electrodes must be electrochromic; usually it consists of tungsten oxide. READ MORE

7. 10. Enzyme-Based Amperometric Biosensors in Flow-Systems for Biomolecule Detection

   Author : Niklas Larsson; Centrum för analys och syntes; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microdialysis; Liquid chromatography; Flow injection; Polyelectrolytes; Carbohydrate; Mediator; Dehydrogenase; Peroxidase; Oxidase; Enzyme; Amperometric detection; Carbon paste; Biosensor; Graphite electrode; On-line monitoring; Analytical chemistry; Analytisk kemi;

   Abstract : Amperometric enzyme based biosensors were designed, developed and characterised in flow systems. Solid graphite and carbon paste electrodes were used as support for enzyme immobilisation. Both mediated and direct electron transfers between redox enzymes and electrodes were utilised for biosensor construction, as well as coupled enzyme systems. READ MORE
