  1. 1. 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

  3. 2. Polymer Actuators for Micro Robotic Applications

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

    Sammanfattning : 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.

    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. 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

  7. 5. Piezoactuators for Microfluidics : Towards Dynamic Arraying

    Författare :Tobias Lilliehorn; Stefan Johansson; Göran Stemme; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Microfluidics can be used to increase performance, reduce reagent consumption and increase throughput in chemical analysis. With the forthcoming development of more advanced microfluidic systems, the integration of actuating elements becomes essential, giving the ability to control and manipulate fluid flow as well as sample or other components.
