  1. 1. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    Master-uppsats, Linköpings universitet/Biosensorer och bioelektronik

    Författare :Daniel Falk; [2015]
    Nyckelord :Biosensors; Bioelectronics; Microactuators; Conjugated polymers; Polypyrrole; PEDOT; Soft Lithography; Microcontact printing; Vapor phase polymerization; Drop-on-Demand printing; Photolithography; Lift-off;

    Sammanfattning : Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. LÄS MER

  3. 2. PIEZOELEKTRISK TRYCKSENSOR : En undersökning om textil struktur och piezoelektricitet

    Kandidat-uppsats, Akademin för textil, teknik och ekonomi

    Nyckelord :Piezoelectricity; poly vinylidene fluoride PVDF ; textile pressure sensor; structure; Piezoelektricitet; poly vinyldifluorid PVDF ; textil trycksensor; struktur;

    Sammanfattning : Arbetet syftar till att skapa en prototyp av en textil trycksensor som kan känna av och skilja på olika typer av belastning. En lämplig metod för att på ett vetenskapligt sätt testa sagda prototyp har också utvecklats. LÄS MER

  4. 3. Textile Sensor Using Piezoelectric Fibers for Measuring Dynamic Compression in a Bowel Stent

    Master-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :ANNA VAHLBERG; [2014]
    Nyckelord :Piezoelectricity; advanced textile structure; textile sensor; piezoelectric poly vinylidene fluoride; PVDF ; textile medical device; self-sensing stent;

    Sammanfattning : In this experimental study the in-lined poled piezoelectric poly(vinylidene fluoride)(PVDF) bicomponent fiber was investigated the suitability in applications within the area of textile sensors when used in a bowel stent. Today there are only piezoelectric films made of PVDF available. LÄS MER

  5. 4. Characterization and Manufacturing of Textile Pressure Sensors based on Piezoelectric Fibres

    Master-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :NIEKE SARINK; [2014]
    Nyckelord :Piezoelectric; Poly vinylidene fluoride PVDF ; textile pressure sensor; knitting;

    Sammanfattning : The main purpose of this thesis was to investigate and characterize the use of piezoelectric yarn for use in textile (fingertip) pressure sensors in glove applications. Such applications could include healthcare, security and safety, game applications or intelligent control. Piezoelectric materials generate a voltage when pressed or squeezed. LÄS MER

  7. 5. Piezoelectric behaviour of woven constructions based on poly(vinylidene fluoride) bicomponent fibres

    Master-uppsats, Högskolan i Borås/Institutionen Textilhögskolan

    Författare :KARIN RUNDQVIST; [2013]
    Nyckelord :Piezoelectricity; poly vinylidene; fluoride ; PVDF ; ; bicomponent fibre; conductive fibres; textile sensor; tensile sensor; weaving;

    Sammanfattning : During this project it was investigated how the newly developed piezoelectric PVDF bicomponent fibre behaved when integrated in different weave constructions. The possibility to integrate conductive yarns as outer electrode was studied in order to see if it was possible to create a fully textile piezoelectric sensors. LÄS MER
