  1. 1. UV laser patterning of silicone-based soft electrode grids

    Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Maria Jakobsson; [2023]
    Nyckelord :Soft electrodes; Wearable electrodes; UV laser; Laser ablation; Laser curing; Polydimethylsiloxane; PDMS; Silver flakes; Teknisk biologi; Teknisk biologi;

    Sammanfattning : Roughly 123 million people worldwide are affected by conditions such as epilepsy, dementia, and cardiovascular diseases. Wearable electrodes are currently used to monitor these conditions short-term. Long-term monitoring would allow for predicting seizures and could be used as a preventive treatment. LÄS MER

  3. 2. Method Development for Analysis of Antioxidants for Use in Areas Sensitive to Discoloration and of High Molecular Weight UV-Stabilizers

    Master-uppsats, KTH/Kemi

    Författare :David Camaj; [2022]
    Nyckelord :Phenolic Antioxidants; UV-Stabilizers; Analysis Method development; Capillary Electrophoresis; MALDI-TOF; Fenoliska Antioxidanter; UV-stabilisatorer; Analysmetodutveckling; Kapillärelektrofores; MALDI-TOF;

    Sammanfattning : Vanliga fenoliska antioxidanter som används i polymerer orsakar färgändringar i polymeren. Detta arbete berör antioxidanter med jämförelsevis begränsad färgändring, med fokus på att utveckla metoder för analys av dessa. UV-stabilisatorerna UV2, UV5, UV1, UV4, UV3 och UV6 är också inkluderade i detta arbete. LÄS MER

  4. 3. Towards laser fabrication of soft neural electrodes

    Master-uppsats, Linköpings universitet/Laboratoriet för organisk elektronik; Linköpings universitet/Tekniska fakulteten

    Författare :John Schill; [2022]
    Nyckelord :Stretchable electrodes; UV-laser ablation; Silver nanowires; 355 nanoseconds laser; electrode patterning; Teknisk biologi; Teknisk biologi;

    Sammanfattning : Electronic devices define our everyday lives. They are often large, rigid, and brittle. Modern medical science has come so far as to start using miniature electronic devices to monitor many types of diseases. LÄS MER

  5. 4. Adapting FDM 3D-printing for the manufacture of microfluidic devices

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Oskar Andersson; [2021]
    Nyckelord :3D-printing; addative manufacturing; fused deposition modelling; FDM; fused filament fabrication; FFF; microfluidics; microfluidic devices; lab-on-a-chip; microchannels; micro-channels; resolution; settings; Technology and Engineering;

    Sammanfattning : Microfluidic devices have so far not seen widespread use, even though they could potentially be cheaper, better and faster than traditional methods. A possible reason for this is the lack of a middle step between one-of-a-kind experimental devices and cheap mass produced devices. LÄS MER

  7. 5. Simulated Laser Triangulation with Focus on Subsurface Scattering

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Hilma Kihl; Simon Källberg; [2021]
    Nyckelord :Laser triangulation; subsurface scattering; simulation; speckle pattern; Gaussian beam; Blender; spruce wood; blister package;

    Sammanfattning : Practical laser triangulation sessions were performed for each measurement object to obtain ground truth data. Three methods for laser line simulations were implemented: reshaping the built-in light sources of Blender, creating a texture projector and approximating a Gaussian beam as a light emitting volume.
