    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

  7. 5. 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
