  1. 1. Piezoelectric power harvesting from mechanical strain

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Edin Spahic; [2021]
    Keywords : piezoelectricity; roller bearing; strain; power harvesting;

    Abstract : Piezoelectric power harvesting is a field of active research. Most piezoelectric power harvesters are designed around harvesting energy from vibrations. READ MORE

  3. 2. Energy Harvesting for Electronic Systems

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Oscar Ridell; Pål Nilsson; [2017]
    Keywords : Energy Harvesting; Energy Scavenging; Photovoltaic cells; Electromagnetics; Piezoelectric element; Radiofrequency; Thermoelectric element; Science General; Technology and Engineering;

    Abstract : Energy harvesting enables products to become more self-sufficient of power and offers the possibility to avoid battery exchange and power cables. The performance and applicability of the most promising or popular small scale energy harvesting technologies are investigated in this thesis. READ MORE

  4. 3. 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

  5. 4. 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. 5. Ab initio piezoelectricity and energy landscape of Y0.375Al0.625N

    University essay from Teoretisk Fysik

    Author : Christopher Tholander; [2011]
    Keywords : ;

    Abstract : There is high industrial demand for materials with a high piezoelectrical response which are stable at high temperatures. A recent study on ScAlN has explained the microscopic origin of the increased piezoelectric response in the alloy and its effect on the energy landscape. Y is a promising candidate to observe the same phenomena. READ MORE
