1. Fundamentals and applications of microplasma sources : Actuating, Sensing, and Nonlinearly Approximating
Sammanfattning : The research presented in this thesis covers a wide range of applications for, and integrations of, a stripline split-ring resonator (SSRR) microplasma source. Common throughout the presented works is the always present, but sometimes secondary, focus on analyzing the light and matter that is emitted as gas is flowed through theplasma of the SSRR. LÄS MER
2. Extending Microsystems to Very High Temperatures and Chemically Harsh Environments
Sammanfattning : Aiming at applications in space exploration as well as for monitoring natural hazards, this thesis focuses on understanding and overcoming the challenges of extending the applicability of microsystems to temperatures above 600°C as well as chemically harsh environments. Alumina and zirconia high-temperature co-fired ceramics (HTCC) with platinum as the conductor material, have in this thesis, been used to manufacture a wide range of high-temperature tolerant miniaturized sensors and actuators, including pressure and flow sensors, valves, a combustor, and liquid monopropellant microthrusters.
