  1. 1. Piezoactuators for Miniature Robots

    Författare :Urban Simu; Jean-Marc Breguet; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; English; engelska;

    Sammanfattning : Challenges in the realisation of a miniature robot are both to handle the complexity of such a system, and to cope with effects of the actual reduction in physical size of all the parts. In particular, the mechanisms for locomotion have to be analysed. LÄS MER

  3. 2. Miniature Phase-Transistion Actuators

    Författare :Lena Klintberg; Lars Montelius; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : Clearly, there is a need for simple, strong actuators capable of large strokes in miniaturized systems such as valves and optical shutters.The basis for this work is the microstructure technology with processing techniques adopted from the integrated circuit industry. LÄS MER

  4. 3. Microfabrication and evaluation of piezoceramic actuators

    Författare :Mats Bexell; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Miniature motor; piezomotor; piezoelectric; actuator; assembly; piezoceramic; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Sammanfattning : There is an increasing interest for miniaturised actuators in a number of technological fields such as automation or medicine (e.g. prostheses, medical pumps etc.). LÄS MER

  5. 4. Vikingatida sköldar : Ting, bild och text som associativt fält

    Författare :Kerstin Odebäck; Mats Burström; Anders Andrén; Terje Gansum; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Viking Age; shields; miniature shields; picture stones; rune stones; burials; skaldic poetry; warrior ideal; Norse mythology; arkeologi med inriktning mot allmän arkeologi; Archaeology with General Specialisation;

    Sammanfattning : Shields are among the most iconic artefacts associated with the Viking Age. Even though shields occur frequently in various archaeological and written sources, the function and meaning of shields have been sparsely researched and they have mainly been considered relevant as part of the warrior’s equipment.

  7. 5. Nanofabrication of Single Electron Transistors and Evaluation of Miniature Biosensors

    Författare :Linda G. M. Olofsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; miniaturization; nanoparticles; impedance; single electron tunneling; biosensors; surface plasmon resonance;

    Sammanfattning : This thesis deals with miniaturization in two different fields: electronics and biosensing. The first part deals with fabrication and measurements of two nanoscale structures - a self-assembled single electron transistor and a (potential) single junction device. LÄS MER
