1. Paraffin Actuators in Microfluidic Systems
Sammanfattning : There is a need for reliable valves and pumps in microfluidics. A good microactuator is the key for low cost and high performance of these components.Paraffin wax is a promising material to be used as actuator material as is can produce large forces and large strokes. LÄS MER
2. Modeling and Verification of Ultra-Fast Electro-Mechanical Actuators for HVDC Breakers
Sammanfattning : The continuously increasing demand for clean renewable energy has rekindled interest in multi-terminal high voltage direct current (HVDC) grids. Although such grids have several advantages and a great potential, their materialization has been thwarted due to the absence of HVDC breakers. LÄS MER
3. Exploiting individual wheel actuators to enhance vehicle dynamics and safety in electric vehicles
Sammanfattning : This thesis is focused on individual wheel actuators in road vehicles intended for vehicle motion control. Particular attention is paid to electro-mechanical actuators and how they can contribute to improving vehicle dynamics and safety. LÄS MER
4. Miniature Phase-Transistion Actuators
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
5. Actuators for autonomous microrobots
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
