    Sammanfattning : Measurement of the concentration of greenhouse gases, such as carbon dioxide(CO 2 ) and methane (CH 4 ), in the atmosphere has received significant attention in the last few decades. This work focusses on the development of high-performance thermopile detectors for use with the non-dispersive infrared (NDIR) measurements of such gases. LÄS MER

  4. 3. Design, Fabrication and Optimization of Thermal Radiation Detectors Based on Thin Polymer Membranes

    Författare :Claes Mattsson; Hans-Erik Nilsson; Göran Thungström; Ylva Bäcklund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal detector; Polymer; Membrane; SU-8; Electronics; Elektronik;

    Sammanfattning : The number of applications in which infrared radiation sensors are used is increasing. In some applications, the cost of the sensor itself is an issue, and simple solutions are thus required. In this thesis, the investigations have related to the use of thin polymer membranes in thermal infrared sensors, such as bolometers and thermopiles. LÄS MER
