The result can be used as a basis for further projects.The project starts with force and strain measurements. The project then evolves to incorporate multiple FBG sensors. READ MORE

  3. 2. Field-effect transistor based biosensing of glucose using carbon nanotubes and monolayer MoS2

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Nathan Ullberg; [2019]
    Keywords : field-effect transistor; biosensor; glucose; carbon nanotube; MoS2; 1D materials; 2D materials; nanotechnology; FET;

    Abstract : As part of the EU SmartVista project to develop a multi-modal wearable sensor for health diagnostics, field-effect transistor (FET) based biosensors were explored, with glucose as the analyte, and carbon nanotubes (CNTs) or monolayer MoS2 as the semiconducting sensing layer.  Numerous arrays of CNT-FETs and MoS2-FETs were fabricated by photolithographic methods and packaged as integrated circuits.

  4. 3. Differentiation and classification of different materials on a touch-screen using a piezoelectric contact microphone

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Anders Björn; [2016]
    Keywords : Technology and Engineering;

    Abstract : In this report, a potential improvement of an optical touch screen solution by means of acoustic sensing is presented. The goal is to utilize the different vibration patterns that arise when different materials touch the screen to be able to identify them. READ MORE

  5. 4. PLASMONIC NANOPORES: exploring new possibilities in DNA sensing and trapping

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Francesca Nicoli; [2013]
    Keywords : ;

    Abstract : In this work we explore the new DNA sensing and trapping possibilities offered by a plasmonic nanopore. This new device combines the sensing capability of solid state nanopores with the effects arising from the collective oscillation of electrons in gold nanoparticles (plasmons). READ MORE

  6. 5. Investigation of ZnO nanorods for UV detection

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : David Boban Rihtnesberg; [2011]
    Keywords : ;

    Abstract : In recent years, there has been increasing interest in ZnO semiconductors for optoelectronic application in the UV wavelength region due to its large exciton binding energy of 60 meV and wide bandgap energy of 3,37 eV at room temperature. One-dimensional ZnO nanostructures such as nanorods or nanowires have been considered as promising candidates for UV sensing and detecting applications owing to its high surface to volume ratio.
