Flow sensor
Symerský, Tomáš ; Psota, Boleslav (referee) ; Kosina, Petr (advisor)
This diploma thesis is divided into two parts - theoretical and practical. In its first, theoretical part, deals with the theory of fluid and gas flow, heat transfer and diversification of sensors for flow measurement working on the electrical principle. It also deals with thermodynamic principle, which can be used for measuring very small flow and low-temperature ceramics that is used to implement microcanals for sensing very low flows. The practical part of the thesis deals with the very simulation of the entire structure in the program “COMSOL Multiphysics” - both in 2D and 3D views. Then there is shown the implementation and measurement of the flow sensor in a low-temperature ceramics, working on a thermodynamic principle.

Capacitive sensor in low temperature co-fired Ceramic
Symerský, Tomáš ; Řezníček, Michal (referee) ; Kosina, Petr (advisor)
This bachelor thesis deals with theoretical knowledge of basic materials especially of a low-temperature ceramics, which enables creating multi-layer structures. Different defects occur by forming these structures, especially in the area of cavernas and micro-tubules. This thesis uses different methods which lead to an elimination of these defects. The thesis also deals with techniques which can be used to a realization of these sensors. Achieved knowledge helped to draft and realize the capacity sensor of flow and pressure in a low-temperature ceramics. The pressure sensor was tested by the load in the frequency spectrum, while the flow sensor was tested for different substances.
