  2. 1. Applications of active materials

    Author : Erik Edqvist; Greger Thornell; Bengt Lundberg; Edwin Jäger; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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;

    Abstract : 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. READ MORE

  4. 2. Ultra-wideband Antenna and Radio Front-end Systems

    Author : Magnus Karlsson; Anders Rydberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless communication; ultra-wideband; radio communication; UWB bandwidth; antenna parallelism; Electrical engineering; Elektroteknik;

    Abstract : The number of wireless communication applications increase steadily, leading to the competition for currently allocated frequency bands. Pressure on authorities around the world to permit communications in higher and wider frequency ranges to achieve higher wireless capacity than those existed in the past has resulted in several new specifications.

  5. 3. Alternative electronic packaging concepts for high frequency electronics

    Author : Wolfgang Peter Siebert; Sture Petersson; Shaofang Gong; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Connector; cooling; electronic; elastomer interconnect; EMC; shielded enclosure; high frequency; PCB; PWB; reverberation chamber; seams; soldering; twisted pair cable; Elektroteknik; Electrical engineering; Elektroteknik;

    Abstract : The aim of the research work presented here, is to contribute to the adaptation of electronic packaging towards the needs of high frequency applications. As the field of electronic packaging stretches over several very different professional areas, it takes an interdisciplinary approach to optimize the technology of electronic packaging. READ MORE

  6. 4. Polymer Actuators for Micro Robotic Applications

    Author : Erik Edqvist; Stefan Johansson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Micro actuator; PVDF-TrFE; I-SWARM; Multilayer actuator; Materials science; Teknisk materialvetenskap;

    Abstract : In this thesis a multilayer actuator structure is developed for the I-SWARM project. In order to build an energy efficient and low voltage actuator system for the 3x3x3 mm3 robot, the resonance drive mode in combination with a ten layer multilayer structure build upon the most suitable substrate material was used.
