2. 1. Fundamentals and applications of microplasma sources : Actuating, Sensing, and Nonlinearly Approximating

   Author : Ragnar Seton; Anders Persson; Donatella Puglisi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Stripline Split-ring Resonator; Microplasma; Optical Emission Spectroscopy; Medical Technology; Transcutaneous Blood Gas Monitoring; Small Satellites; Microthruster; Cold Gas Thruster; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : 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.

4. 2. Extending Microsystems to Very High Temperatures and Chemically Harsh Environments

   Author : Zahra Khaji; Lena Klintberg; Klas Hjort; Greger Thornell; Frank Niklaus; Uppsala universitet; []
   Keywords : HTCC; MEMS; MST; Microcombustor; Microthruster; Single-use valve; Wireless pressure sensor; flow sensor; in-situ electroplating; Monopropellant; Platinum; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

   Abstract : 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.
