    Författare :Zahra Khaji; Lena Klintberg; Klas Hjort; Greger Thornell; Frank Niklaus; Uppsala universitet; []
    Nyckelord :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;

    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.
