  1. 6. A Flexible, Low-cost Approach to Slippage Detection using Pyroelectricity

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Anders Robin Larsson; [2020]
    Keywords : pyroelectricity; slippage detection; pvdf;

    Abstract : Myoelectric prosthesis on the market today are mostly very expensive and rarely allow the amputee any feedback, leaving the users separated from their own robotic arm. Integrating sensory systems into an arm which needs to be replaced several times during a lifetime may also not be cost efficient. READ MORE

  3. 7. An Investigation on PVDF Piezoelectric Elements and Linear Array Transducers

    University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Ali Alkhudri; [2017]
    Keywords : Ultrasonic Transducer; Piezoelectric Element; PVDF; Frequency; Ultrasound Wave Penetration; PZT; Acoustic Impedance; raw data; linear array transducer; Technology and Engineering;

    Abstract : Ultrasonic waves are widely used in different application e.g. for sonar scanning in water and fetal imaging. Furthermore it is used for doing measurements on different materials to determine the thickness of the material or the velocity of sound inside it. READ MORE

  4. 8. Effect of heavy metals on syngas fermentation

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Steven Wainaina; [2016]
    Keywords : Syngas biomethanation; biological water-gas-shift; heavy metals;

    Abstract : The goal of this work was to establish the suitable and limiting concentrations of Zn, Cu and Mn compounds during syngas fermentation. The results showed that cells encased in polyvinylidene difluoride (PVDF) membranes had a faster accumulation of methane in reactors containing fermentation medium dosed with 5 mg/L of each heavy metal compared to free cells.

  5. 9. Patterning of Highly Conductive Conjugated Polymers for Actuator Fabrication

    University essay from Linköpings universitet/Biosensorer och bioelektronik

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

    Abstract : 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. READ MORE

  6. 10. Textile Actuator Fibres : Investigation in materials and methods for coiled polymer fibre muscles

    University essay from Akademin för textil, teknik och ekonomi

    Author : Rebecca Melvinsson; [2015]
    Keywords : Textile actuators; Soft robots; Coiled muscles; PVDF; SMP; Fibre Anisotropy; Thermal actuation; α-relaxation;

    Abstract : This thesis contains an investigation in materials and methods for coiled polymer muscles where the end application in mind is to be integrated in a textile structure such as an exo-skeleton glove. Previous artificial muscle fibres have proved little success due to performance, cost and scalability. READ MORE
