  1. 1. Design and engineering of light-driven dynamic films for bioelectronic interfacing

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Luca Terenzi; [2023]
    Nyckelord :Conductive polymers; Stimuli responsive materials; Azopolymers; Cell-chip coupling; Bioelectronics; Konduktiva polymerer; Stimuli-känsliga material; Azopolymerer; Cell-chip-koppling; Bioelektronik;

    Sammanfattning : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. LÄS MER

  3. 2. An investigation of the relationships between electrotactile stimulus parameters, primary afferent response, and perceived sensation

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Jessica Sofie Louise Vidmark; [2018]
    Nyckelord :electrotactile stimulation; psychophysical sensation; primary afferent response; sensory feedback; prosthetics; elektrisk hudstimulering; psykofysisk respons; primärafferent respons; sensorisk återkoppling; proteser;

    Sammanfattning : Sensory feedback possesses the possibility of adding a new dimension to many applications, including, but not limited to, prosthetics and surgical robots for improved control, virtual reality for incorporation of another sense, and phantom limb pain reduction for amputees. Electrotactile stimulation provides a compact, light-weight, energy efficient, highly responsive, and non-invasive option for sensory feedback; however, it has been found to commonly elicit unnatural or uncomfortable sensations for the user.

  4. 3. Previously undiscovered neurons of the Bogong moth brain: 3D-reconstruction and registration

    Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

    Författare :Olle Claesson; [2016]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The Australian Bogong moths are thought to have the ability to sense the earth’s magnetic field. This ability has to be reflected in the animal’s neural architecture. Hence reconstruction of three brain neurons was carried out, though these respond to visual stimulation instead of magnetic. LÄS MER

  5. 4. Synthesis and characterization of amine-functionalized microgel particles and their subsequent assembly into colloidal molecule-like clusters by droplet-based microfluidics

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Emil Gustafsson; [2015]
    Nyckelord :Physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The ability of thermoresponsive, amine-functionalized microgel particles to take part in microgelmicrogel inter-cross-linking has previously been reported in the literature, in connection to applications such as for example the formation of stimuli-responsive colloidal gels and colloidosomes [1]. This thesis deals with the synthesis of such thermoresponsive, cross-linkable microgels and their subsequent assembly into clusters using droplet-based microfluidics, with the goal of forming responsive colloidal molecules with well-defined valency.

  7. 5. Microgels at ultrahigh densities : a small angle neutron scattering study

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Sofi Nöjd; [2012]
    Nyckelord :Fysikalisk kemi; Chemistry;

    Sammanfattning : Populärvetenskaplig sammanfattning Microgelpartiklar är runda partiklar som har förmågan att ändra storlek beroende på olika yttre påverkan. I detta projekt har vi tittat på partiklar som blir upp till 10 gånger mindre när temperaturen höjs från 15˚C till 39˚C. LÄS MER
