1. 11. Textile Sensor Using Piezoelectric Fibers for Measuring Dynamic Compression in a Bowel Stent

   University essay from Högskolan i Borås/Institutionen Textilhögskolan

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

   Abstract : 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. READ MORE

3. 12. Rapid Bio-methanation of Syngas by High Cell-density in Reverse Membrane Bioreactors

   University essay from Högskolan i Borås/Institutionen Ingenjörshögskolan

   Author : Konstantinos Chandolias; [2014]
   Keywords : syngas; fermentation; reverse; membrane; bioreactor; bio-methanation; high cell density;

   Abstract : Syngas fermentation via gasification is a two-stage process, which contains gasification of feedstock into syngas and syngas bio-methanation by anaerobic microorganisms. This project is a study on syngas fermentation. The gasification feedstock can be difficult-to-degrade solid waste so; waste volumes are reduced while green energy is produced. READ MORE

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

   University essay from Högskolan i Borås/Institutionen Textilhögskolan

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

   Abstract : 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. READ MORE

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

   University essay from Högskolan i Borås/Institutionen Textilhögskolan

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

   Abstract : 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. READ MORE

6. 15. Fabrication and Characterization of Individually Addressable Polypyrrole Trilayer Microactuators

   University essay from Biosensorer och bioelektronik; Tekniska högskolan

   Author : Nnamdi Felix Nworah; [2012]
   Keywords : Fabrication; Characterization; Polypyrrole; Electropolymerization; Photolithograph;

   Abstract : Conjugated polymers are organic polymers that can conduct electricity. They undergo a volume change upon redox reaction and can be used as an active material in some micro- actuator system. Micro-actuators are useful in biomedical and electronic application. READ MORE
