Barium Strontium Titanate Thin Film Growth with rotational speed variation as a satellite temperature sensor prototype

In this paper, [Inline formula] deposition method with spin coating technique in order to improve its dielectric properties. This study was to find out how the effect of mustard chlorophyll exposure on [Inline formula] films was analyzed using x-ray diffraction and micro-Raman spectroscopy based on crystal structure and the stability of the film phase BST doping mustard chlorophyll. The annealing process is carried out as a high temperature heating step which aims to restore the physical and crystalline properties of the film which may change during the film growth process. The specified annealing temperature is 850 °C with a holding time of 8 h. The effect of chlorophyll solidification was observed by applying variations of chlorophyll mustard concentration, namely 0%, 2.5%, and 5%. The crystal structure type and film lattice parameters were confirmed using X-Ray Diffraction with the measurement angle starting from an angle of 10° to 80° with an angle increase of 0.02°.

Electrohydrodynamic (EHD) inkjet printing is an efficient technique for printing multiple sensors in a multifaceted area. It can be applied to various fields according to the shape of the printing result and the algorithm employed. In this study, temperature sensors capable of detecting heat sources were fabricated. Inks suitable for EHD inkjet printing were produced, and optimal parameters for printing were determined. Printing was performed using the corresponding parameters, and various printing results were obtained. Furthermore, an experiment was conducted to confirm the temperature measurement characteristics of the results and the tolerance of the sensor. Grid-type sensors were fabricated based on the results, and the sensor characteristics were confirmed in an orthogonal form. Heat was applied to arbitrary positions. Resistance to changes due to heat was measured, and the location at which the heat was generated was detected by varying the change in resistance. Through this study, efficient heat control can be achieved, as the location of the heat source can be identified quickly.
