  1. 1. Screen Printed Thermoelectric Devices

    Författare :Andreas Willfahrt; Xavier Crispin; Werner Zapka; Linköpings universitet; []
    Nyckelord :Screen printing; thermoelectric generator; Seebeck effect; energy harvesting;

    Sammanfattning : Thermoelectric generators (TEG) directly convert heat energy into electrical energy. The impediments as to why this technology has not yet found extensive application are the low conversion efficiency and high costs per watt. On the one hand, the manufacturing process is a cost factor. LÄS MER

  3. 2. Highly-Efficient Energy Harvesting Interfaces for Implantable Biosensors

    Författare :Janko Katic; Ana Rusu; Saul Rodriguez; Gabriel Rincón-Mora; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy harvesting interface; thermoelectric generator; glucose biofuel cell; power management; dc-dc converter; boost converter; zero-current switching; zero-voltage switching; implantable biosensor; Energiskördsgränssnitt; termoelektrisk generator; glukosbiobränslecell; energihantering; DC-DC-omvandlare; boost-omvandlare; inplanterbar biosensor; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : Energy harvesting is identified as an alternative solution for powering implantable biosensors. It can potentially enable the development of self-powered implants if the harvested energy is properly handled. This development implies that batteries, which impose many limitations, are replaced by miniature harvesting devices. LÄS MER

  4. 3. Thermoelectric Devices with Electronic and Ionic Conducting Polymers

    Författare :Zia Ullah; Xavier Crispin; Magnus Berggren; Marisol Martin-Gonzalez; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; conducting polymers; thermoelectric devices;

    Sammanfattning : The energy consumption in the world is continuously growing and the sources of energy are largely dominated by fossil fuels. However, the resources of oil, gas and coal are diminishing in capacity. Moreover the CO2 emissions arising from their combustion is a great concern because it induces climate changes that threaten our habitat. LÄS MER

  5. 4. Waste-heat Recovery Using Thermoelectricity and Silicon Carbide Power Electronics

    Författare :Arash Edvin Risseh; Hans-Peter Nee; Torbjörn Thiringer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermoelectricity; Power converter; Silicon Carbide; MOSFET; Power management; Thermoelectric generator; Renewable energy; Vehicle; Power electronic; Waste heat; Ultra-low inductance; Power module; Termoelektrisk energiomvandling; Kiselkarbid MOSFET; Effektomvandlare; Förnybar energikälla; Effektelektronik; Spillvärme; Effektmodul; Låg induktiv module; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Energy consumption in the world has increased continuously due to a growing population and increased energy consumption per capita. Moreover, the largest part of consumed energy still comes from fossil sources which in 2016 was more than 130 PWh. LÄS MER

  7. 5. Multiscale Simulation Methods for Thermoelectric Generators

    Författare :Olle Högblom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust gas heat recovery; subgrid modelling; CFD; Thermoelectrics; Contact resistances;

    Sammanfattning : Rising energy prices and greater environmental awareness, along with stringent emissions legislation, in the automotive industry make it possible to introduce techniques in the aftertreatment system that have previously been unprofitable. One such technique, studied here, is heat recovery from exhaust gases using thermoelectric generators. LÄS MER
