  1. 1. Applications of active materials

    Författare :Erik Edqvist; Greger Thornell; Bengt Lundberg; Edwin Jäger; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Energy efficient; microsystem; resonating cantilevers; microactuators; P VDF-TrFE ; surface mounting assembly; multi layers; flexible printed circuit board; conveyer; three legged; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Energy efficiency is a vital key component when designing and miniaturizing self sustained microsystems. The smaller the system, the smaller is the possibility to store enough stored energy for a long and continuous operational time. LÄS MER

  2. 2. Flexible Circuits and Materials for Creating Large-Area RFID Reader Antenna Systems

    Författare :Xiaotian Li; Johan Sidén; Henrik Andersson; Jonny Johansson; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the applications for RFID technology is to monitor and position RFID-tagged objects over large volumes. To achieve this, one possible option is to implement RFID reader antennas, which are relatively thin but with significantly large areas, and place them beneath the RFID-tagged objects. LÄS MER

  3. 3. Robotized Production Methods for Special Electric Machines

    Författare :Erik Hultman; Mats Leijon; Jörg Franke; Uppsala universitet; []
    Nyckelord :Industrial robotics; Assembly automation; Large-scale production; Cable winding; Linear generator; Wave energy converter; Wave power; Engineering education; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : A research project on renewable energy conversion from ocean waves to electricity was started at the Division of Electricity at Uppsala University (UU) in 2001. The Wave Energy Converter (WEC) unit developed in this project is intended to be used in large offshore WEC farms and has therefore been designed with large-scale production in mind. LÄS MER

  4. 4. Actuators for autonomous microrobots

    Författare :Niklas Snis; Stefan Johansson; Urban Simu; Alvo Aabloo; Uppsala universitet; []
    Nyckelord :Engineering physics; Locomotion; Microrobot; PZT; P VDF-TrFE ; Autonomous; Multilayer; Actuator; Teknisk fysik;

    Sammanfattning : This thesis presents actuators used in autonomous microsystems. Characteristic for all actuators presented is the low drive voltage and the low power consumption. Different motion mechanisms have been studied and applied in various locomotion modules for microrobots. LÄS MER

  5. 5. Automated Production Technologies and Measurement Systems for Ferrite Magnetized Linear Generators

    Författare :Tobias Kamf; Mats Leijon; Jonas Öhr; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial robotics; automation; self-sensing; calibration; ferrite; linear generator; wave energy; offshore; measurements; electronics; kinetic energy storage; reluctance motor; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : The interest in breaking the historical dependence on fossil energy and begin moving towards more renewable energy sources is rising worldwide. This is largely due to uncertainties in the future supply of fossil fuels and the rising concerns about humanity’s role in the currently ongoing climate changes. LÄS MER
